     This Amendment No. 1 ("Amendment No. 1") amends and restates in its
entirety the Report on Schedule 13D (the "Schedule 13D"), originally filed on
February 11, 2000, by the Reporting Persons, with respect to the shares of
common stock, $0.01 par value per share (the "Common Shares") of Winstar
Communications, Inc., a Delaware corporation (the "Issuer").

     Item 1. Security and Issuer.

     The class of equity securities to which this statement relates is the
Common Shares of the Issuer. The principal executive offices of the Issuer are
located at 685 Third Avenue, New York, NY 10017.

     The Schedule 13D was filed due to the acquisition on February 1, 2000 (as
described below in Item 3) of Series G Senior Cumulative Participating
Convertible Preferred Stock, $.01 par value per share (the "Series G Shares"),
of the Issuer. The Series G Shares are convertible into Common Shares at any
time at the option of the holder of Series G Shares. Each holder of Series G
Shares is entitled to vote on all matters and is entitled, subject to the
Voting Agreement (as described in Item 6) to that number of votes equal to the
number of Common Shares into which such holder's Series G Shares could be
converted. If any cash dividends are paid on the Common Shares, the holders of
the Series G Shares are entitled to receive such cash dividend on an
as-converted basis. In addition, each Series G Share pays cumulative dividends
at a rate equal to the excess (if any) of (i) 5.75% per annum on its
liquidation preference over (ii) the amount of any regular cash dividends per
Series G Share that have been paid during the applicable dividend period on the
Common Shares. Such dividends are payable quarterly in arrears on March 15,
June 15, September 15 and December 15 of each year to the record holders of
Series G Shares as of March 1, June 1, September 1 and December 1. The Issuer
has the option to pay these dividends in cash or by adding the amount of the
dividend to the liquidation preference.

     This Amendment No. 1 to Schedule 13D is being filed due to the recent
acquisition (as described below in Item 3) of Series H Senior Cumulative
Participating Convertible Preferred Stock, $.01 par value per share (the
"Series H Shares") of the Issuer, and warrants to purchase up to an aggregate
of 1,888,904 shares of Common Shares (the "Warrants") of the Issuer. The Series
H Shares are convertible into Common Shares at any time at the option of the
holder of Series H Shares. Each holder of Series H Shares is entitled to vote
on all matters and is entitled, subject to the Voting Agreement, to that number
of votes equal to the number of Common Shares into which such holder's Series H
Shares could be converted. If any cash dividends are paid on the Common Shares,
the holders of the Series H Shares are entitled to receive such cash dividend
on an as-converted basis. In addition, each Series H Share pays cumulative
dividends at a rate equal to the excess (if any) of (i) 12.5% per annum on its
liquidation preference over (ii) the amount of any regular cash dividends per
Series H Share that have been paid during the applicable dividend period on the
Common Shares. Such dividends are payable quarterly in arrears on March 15,
June 15, September 15 and December 15 of each year to the record holders of
Series H Shares as of March 1, June 1, September 1 and December 1. The Issuer
has the option to pay these dividends in cash or by adding the amount of the
dividend to the liquidation preference. The Warrants are exercisable during the
period commencing on the earlier of (i) 180 days from December 6, 2000 and (ii)
the date on which a change of control occurs and ending on December 6, 2005.

three CSFB Funds, including the decision to buy, sell or hold securities which
comprise the assets of each of the CSFB Funds. In addition, EMA must invest in
and dispose of its portfolio securities pro rata and simultaneously with CSFBEP
pursuant to EMA's limited liability company agreement. Thus, CSFB Advisory
Partners may be deemed to be the beneficial owner of the Series G Shares,
Series H Shares, the Warrants and the underlying Common Shares owned by the
CSFB Funds. CSFB Advisory Partners is a wholly-owned subsidiary of the Bank.
The investment committee of CSFB Advisory Partners that oversees the investment
decisions made for the CSFB Funds includes employees of the Private Equity
Division ("Private Equity Division") of the CSFB Business Unit. The Private
Equity Division reports directly to a board of directors of Credit Suisse First
Boston Private Equity ("CSFBPE"), a wholly-owned subsidiary of Credit Suisse
Group ("CSG"). Such board of directors is comprised in part of executive
officers of CSG; both CSG and CSFBPE are corporations formed under the laws of
Switzerland.

     CSFB Bermuda Limited is the managing member of EMA and thus manages and
controls the affairs of EMA which, unlike the other CSFB Funds, is not advised
in its investment decisions by CSFB Advisory Partners. However, pursuant to its
limited liability company agreement, EMA must invest in and dispose of its
portfolio securities pro rata and simultaneously with CSFBEP. CSFB Bermuda
Limited is a subsidiary of the Bank.

     The CSFB Business Unit is engaged in corporate and investment banking,
trading (equity, fixed income and foreign exchange), private equity investment
and derivatives businesses on a worldwide basis. The Bank and its subsidiaries
engage in other separately managed activities, most of which constitute the
independently operated Credit Suisse Asset Management business unit, which
provides asset management and investment advisory services to institutional
investors worldwide. The address of the Bank's principal business and office is
Uetlibergstrasse 231, P.O. Box 900, CH-8045 Zurich, Switzerland.

     The Bank owns directly a majority of the voting stock and all of the
non-voting stock of CSFBI. The ultimate parent company of the Bank and CSFBI,
and the direct owner of the remainder of the voting stock of CSFBI, is CSG.
CSFBI owns 100% of the voting stock of CSFB-USA. CSFBC is a wholly-owned
subsidiary of CSFB-USA. CSFB Bermuda Limited is a wholly owned subsidiary of
CSFBC.

     The principal business of CSG is acting as a holding company for a global
financial services group with five distinct specialized business units that are
independently operated. In addition to the two business units referred to


                                 Page 12 of 40
<PAGE>


above, CSG and its consolidated subsidiaries (other than the Bank and its
subsidiaries) are comprised of (a) the Credit Suisse Private Banking business
unit that engages in global private banking business, (b) the Credit Suisse
business unit that engages in the Swiss domestic banking business and (c) the
Winterthur business unit that engages in the global insurance business. CSG's
business address is Paradeplatz 8, CH-8001, Zurich, Switzerland.

     CSG, for purposes of certain federal securities laws, may be deemed
ultimately to control the Bank and the CSFB Business Unit (including the
Private Equity Division). Due to the separate management and independent
operation of its business units, CSG disclaims beneficial ownership of Common
Shares that may be beneficially owned by its direct and indirect subsidiaries
other than the CSFB Business Unit, CSFB Advisory Partners and CSFB Bermuda
Limited. To the best of its knowledge, CSG and its executive officers and
directors do not beneficially own Common Shares other than as reported in this
Amendment No. 1. CSG hereby undertakes to amend this Amendment No. 1, if
necessary, to include any material information required by Items 2 through 6 of
Schedule 13D with respect to any Common Shares that may be beneficially owned
by executive officers or directors of CSG.

     Hemisphere is the general partner of CSFBEP, CSFBEP Bermuda and
Constellation and, other than the investment activities for which CSFB Advisory
Partners is responsible, thus manages and controls the affairs of these three
CSFB Funds. Hemisphere is engaged in the business of acting as general partner
to collective investment vehicles organized as limited partnerships.
Hemisphere's business address is Hemisphere House, Nine Church Street, Hamilton
HM11, Hamilton, Bermuda. Hemisphere is controlled by Hemisphere Trust, a trust
created for the purpose of acting as beneficial owner of Hemisphere. The
business address of Hemisphere Trust is Hemisphere House, Nine Church Street,
Hamilton HM11, Hamilton, Bermuda. The Hemisphere Trust Company Limited is the
trustee of Hemisphere Trust and is an indirect, wholly-owned subsidiary of
Mutual Risk Management Ltd., a Bermuda company limited by shares. Mutual Risk
Management Ltd. is an international risk management company whose principal
business address is 44 Church Street, Hamilton HM12, Bermuda. To the extent
that The Hemisphere Trust Company Limited controls Hemisphere in its capacity
as trustee of Hemisphere Trust, Mutual Risk Management Ltd. is the ultimate
parent company of Hemisphere.

     The name, citizenship, residence or business address and present principal
occupation or employment, and the name, principal business and address of any
corporation or other organization in which such employment is conducted, of
each executive officer and director of each of CSG, the CSFB Business Unit,
CSFBI, CSFB-USA, CSFBC, CSFB Advisory Partners, CSFB Bermuda Limited,
Hemisphere and Hemisphere Trust Company Limited are set forth on Schedules I-IX
which is incorporated herein by reference. None of the CSFB Funds has any
officers or directors separate from the officers and directors of its general
partner or managing member, as the case may be.

     None of the Reporting Persons, any of the executive officers or directors
of such persons, CSG, CSFBI, CSFB-USA, CSFBC or, to the best of their
knowledge, any of their executive officers or directors, in each case which are
listed on Schedules I-IX, during the last five years (a) has been convicted in
a criminal proceeding (excluding traffic violations or similar misdemeanors) or
(b) has been a party to a civil proceeding of a judicial or administrative body
of competent jurisdiction and as a result of such proceeding was or is subject
to a judgment, decree or final order enjoining future violations of, or
prohibiting or mandating activities subject to, U.S. Federal or State
securities laws or finding any violation with respect to such laws.

     Item 3. Source and Amount of Funds or Other Consideration.

     The beneficial ownership interest in the Common Shares underlying the
Series G Shares was obtained pursuant to the Securities Purchase Agreement
dated as of December 15, 1999 (the "Series G Securities Purchase Agreement")
among the Issuer and one of its wholly-owned subsidiaries, CSFBEP, CSFBEP
Bermuda, EMA Private Equity Fund 1999, L.P. ("EMA 1999") and several other
purchasers. Constellation acquired its beneficial ownership of the Common
Shares underlying the Series G Shares pursuant to an Assignment and Assumption
Agreement dated as of January 12, 2000 among CSFBEP, CSFBEP Bermuda, EMA 1999
and Constellation (collectively, the "Initial CSFB Funds"). EMA acquired its
beneficial ownership of the Common Shares underlying the Series G Shares from
EMA 1999, which is a member of EMA, pursuant to its limited liability company
agreement dated as of December 5, 2000. The acquisition of the Series G Shares
by the Initial CSFB Funds was made in exchange for $400,000,000. The cash
consideration came from funds available for investment of each of the Initial
CSFB Funds.

<PAGE>


     The beneficial ownership interest in the Common Shares underlying the
Series H Shares and the Warrants was obtained pursuant to the Securities
Purchase Agreement dated as of November 7, 2000 among the Issuer and one of its
wholly-owned subsidiaries, CSFBEP, CSFBEP Bermuda and several other purchasers
(the "Series H Securities Purchase Agreement"). Constellation and EMA each

Shares and the Warrants pursuant to an Assignment and Assumption Agreement
dated as of December 6, 2000 among the CSFB Funds. The acquisition of the
Series H Shares and the Warrants by the CSFB Funds was made in exchange for
$111,112,000. The cash consideration came from funds available for investment
of each of the CSFB Funds.

     Separate from the transaction described above in this Item 3 and in
connection with its regular broker-dealer activities, CSFBC engages in purchase
and sale transactions in the Common Shares and certain shares of preferred
stock of the Issuer that are convertible into Common Shares ("Convertible
Shares") as a market maker. As of the filing date, CSFBC held a net position
(including Convertible Shares on an as-converted basis) of 159,583 Common
Shares in its trading account, acquired from time to time in open market
transactions in the ordinary course of business, using working capital funds.
The CSFB Business Unit, by virtue of the Bank's indirect majority ownership of
CSFBC, may be deemed to share the power to vote or direct the vote and dispose
or direct the disposition of the Common Shares held by CSFBC pursuant to its
trading activities described above.

     Item 4. Purpose of Transaction.

     The CSFB Funds have acquired the Series G Shares, the Series H Shares and
the Warrants for investment. The CSFB Funds intend to review from time to time
the Issuer's business affairs and financial position. Based on such evaluation
and review, as well as general economic and industry conditions existing at the
time, the CSFB Funds may consider from time to time various alternative courses
of action. Subject to the Amended and Restated Shareholders Agreement (as
described in Item 6), such actions may include the acquisition of Common Shares
or additional Series G Shares, Series H Shares or Warrants through open market
purchases, privately negotiated transactions, a tender offer, an exchange offer
or otherwise. Alternatively, such actions may involve the sale of all or a
portion of Common Shares, Series G Shares, Series H Shares or Warrants in the
open market, in privately negotiated transactions, through a public offering or
otherwise. Except as set forth above, the CSFB Funds have no plans or proposals
which relate to or would result in any of the transactions described in
subparagraphs (a) through (j) of Item 4 of Schedule 13D. Pursuant to the
Amended and Restated Shareholders Agreement, CSFBEP has the right to designate
one director nominee to the Board of Directors of the Issuer so long as it
continues to beneficially own 40% of its initial holdings of Series G Shares or
Series H Shares on an as-converted basis.

     Item 5. Interest in Securities of the Issuer.

     (a) The CSFB Funds have acquired and, for the purpose of Rule 13d-3
promulgated under the Exchange Act, beneficially own, (i) 400,000 Series G

the Issuer; (ii) 111,112 Series H Shares, representing approximately 41.2% of
the outstanding Series H Shares of the Issuer; and (iii) Warrants to purchase
1,888,904 Common Shares of the Issuer.

     By virtue of holding these Series G Shares, Series H Shares and Warrants,
the CSFB Funds beneficially own approximately 15,608,672 Common Shares
(including 1,888,904 Common Shares issuable upon the exercise of the Warrants),
representing (x) approximately 14.5% beneficial ownership of Common Shares and
(y) 4.9% of the voting power of the Issuer. The individual holdings of the CSFB
Funds are as follows: (i) CSFBEP - 8,896,231 Common Shares, representing
approximately 8.8% beneficial ownership of Common Shares and 2.8% of the voting
power of the Issuer, (ii) CSFBEP Bermuda - 2,487,641 Common Shares,
representing approximately 2.6% beneficial ownership of Common Shares and 0.8%
of the voting power of the Issuer, (iii) EMA - 842,871 Common Shares,
representing approximately 0.9% beneficial ownership of Common Shares and 0.3%
of the voting power of the Issuer and (iv) Constellation - 3,381,929 Common
Shares, representing approximately 3.5% beneficial ownership of Common Shares
and 1.1% of the voting power of the Issuer.

     As described in Item 2 and the following sentence, CSFB Advisory Partners
may be deemed to beneficially own the 15,608,672 Common Shares held by the CSFB
Funds and the 60,000 Option Shares held by Hartley R. Rogers, representing

Rogers, in his capacity as a former Director of the Issuer designated by
CSFBEP, holds options to buy 60,000 Common Shares (the "Options") at the
exercise price of $47.2083 per Common Share (the Common Shares issuable upon
the exercise of the Options are referred to herein as the "Option Shares"). Mr.
Rogers has assigned all economic interest in and power to exercise the Options
to CSFB Advisory Partners.

     As described in Item 2, CSFB Bermuda Limited as the managing member of EMA
may be deemed to be the beneficial owner of the 340,378 Common Shares held by
EMA (which may be voted by such funds pursuant to the Voting Agreement),
representing approximately 0.4% beneficial ownership of Common Shares.

     As of the filing date, CSFBC, in connection with its broker-dealer
activities, beneficially owned a net position (including Convertible Shares on
an as-converted basis) of 159,583 Common Shares. The CSFB Business Unit, by
virtue of the Bank's 100 percent ownership of CSFB Advisory Partners and
indirect majority ownership of CSFBC, may be deemed to beneficially own, on an
as-converted basis, 15,828,255 Common Shares, representing approximately 14.5%
beneficial ownership of Common Shares.

     Hemisphere, as the general partner of CSFBEP, CSFBEP Bermuda and
Constellation, and Hemisphere Trust, as the 100 percent owner of Hemisphere,
may be deemed to beneficially own the 5,954,687 Common Shares held by these
three funds (which may be voted by such funds pursuant to the Voting
Agreement), representing approximately 6.1% beneficial ownership of Common
Shares.

     The foregoing percentages are based on 92,193,015 Common Shares
outstanding on October 31, 2000.

     Except as set forth in this Item 5(a), none of the Reporting Persons nor,

pursuant to the Voting Agreement (as described in Item 6), these Series G
Shares, Series H Shares and Warrant Shares held by the CSFB Funds may not, in
the aggregate, represent more than 4.9% of the outstanding voting power of the
Issuer.

     Hemisphere, as the general partner of CSFBEP, CSFBEP Bermuda and
Constellation, and Hemisphere Trust, as the 100 percent owner of Hemisphere,
may be deemed to share voting power with these three funds over the 5,954,687
Common Shares held by such funds (which may be voted by them pursuant to the
Voting Agreement).

     CSFB Bermuda Limited, as the managing member of EMA, and the CSFB Business
Unit, by virtue of the Bank's indirect majority ownership of CSFB Bermuda
Limited, may be deemed to share voting power with EMA over the 340,378 Common
Shares held by EMA (which may be voted by EMA pursuant to the Voting
Agreement). In addition, the CSFB Business Unit, by virtue of the Bank's 100
percent ownership of CSFB Advisory Partners, and CSFB Advisory Partners may be
deemed to share the power to dispose or direct the disposition of 15,608,672
Common Shares held by the CSFB Funds and the 60,000 Option Shares held by
Hartley R. Rogers. Further, the CSFB Business Unit, by virtue of the Bank's
indirect majority ownership of CSFBC, may be deemed to share the power to vote
or direct the vote and dispose or direct the disposition of the 159,583 shares
