COMMAND

    Service Pack 2 for Win2K

SYSTEMS AFFECTED

    Win2000 with SP2

PROBLEM

    Peter Heath found  following.  Before  applying Windows 2000  SP2,
    his system  (W2K DC  running Exchg2K  & MS  Proxy Client  2.0) ran
    FLAWLESSLY for  months.   When applying  Windows 2000  SP2 to  the
    Windows 2000  SP1 (+  PSP) DC,  DNS errors  appeared, AD tools (at
    server) became unavailable, and Exchange 2000 would not start.

    After three days of troubleshooting, he narrowed the problem  down
    to  MS  Proxy  Client  2.0  and  Service Dependencies referring to
    NTLMSSP.  If ANY, and we mean "ANY", service makes reference to:

        DependOnService: NTLMSSP

    DNS bombs and Exchange 2000 refuses to start.

SOLUTION

    Removing  "DependOnService:  NTLMSSP"  from  ALL  Services  making
    references to it, allows both DNS and Exchange 2000 to START,  but
    internet access is NOT available for ports 25 &110 (Wspcfg.ini)  -
    thus, prevents SMTP & POP3 from functioning.

    You have to do a "Complete System Restore" in order to get  system
    back to it's original (SP1) state.

    Russ Cooper added following.   It appears that the problems  Peter
    Heath experienced with  W2K SP2 and  MS Proxy might  be related to
    the following KB  article, at least  that is the  assumption of an
    anonymous Microsoft poster:
