    Hello

    We have 4 machines running Windows 2000 Server (PDC, BDC and two
    "normal" member servers) and two machines running Windows 2003 Server
    with Citrix Metaframe Presentationserver 3.0

    Previous we were running Windows 2000 Server with Metaframe XP SR3 and
    everything was working fine.
    Since we have made the update of this two machines, file-access to files
    stored on the Windows 2000 machines is incredible slow. Especialy saving
    Fils from MS-Word, but also other programms are making trouble. Saving 2
    MB Word-File may use up to 30 seconds.

    All servers have 1GBit connections and as sayed; with Windows 2000
    File-access was not a problem (there were others ;-)

    Every idea is helpfull!!
    Thank you in advance!

  2. Hello PowerFET,

    We had this issue on a 2003 server when 2000pro and XPpro machines saved
    files to it. Searching through google you'll find you are not alone :) In
    a nutshell, it likely has to do with SMB signing. In our particular case,
    we had to add the registery key 'TcpAckFrequency' with the value of 1
    (reboot server) and all was instantly fixed.

    Do a search either on google or http://support.microsoft.com using the
    keyword TcpAckFrequency and you'll see the exact location. If nothing else,
    just reading over the articles may shed a little more light into you issue.

    Good luck,

    tsc

    I just encountered somthing along these lines. Very slow
    when copying files from server to XP Pro workstations. Slow
    to open up Word/Excel, slow when in accounting software

    I found and deleted an incorrect DNS entry, based on posts
    that DNS problems will cause slow response from the
    network. Especially when logging on.

    What did clear up my problem was setting the NIC to 100
    Half Duplex from Auto. In my case the server had an onboard
    10/100/1000 NIC, going into a 10/100 switch. I was able to
    use the Intel utilities that came on the server to try
    different settings. 100 Half worked best.

    Thank you for your inputs.

    I tried these settings on both of our MetaFrame Servers (2003).

    One Server no works fine. The other one is still slow...
    They both have (should) have the exacte similar Hardware and have the
    actualst Updates...

    any (further) idea?

    Thank you:
