Slow network writes, fast reads after upgrading to WinXP Pro

    I upgraded my Dell Precision 530 workstation from Windows 2000 to Windows XP Pro SP2. The machine is fully patched. The NIC is a 3COM 3C920 integrated fast ethernet controller compatible with the 3COM 3C905C-TX.

    This machine is a member of a large domain (Windows 2000 currently migrating to Windows 2003 - not sure how many servers have been migrated). Since I'm a developer and SQL Server DBA for a 30-person office that is part of a larger organization, I upgraded the machine myself (most users have an imaged desktop). After upgrading, I get the same read performance from any network server (I have access to several different domain member servers, including 5 that I maintain) that I got with Win2K, but the write performance is abysmal. Using PerfMon, for Network bytes received/sec I get close to 6 MB / sec, while network writes are about 120 KB / sec. We use Cisco switches, not sure what models. Usually, this type of problem is due to mismatch between the switch port duplex/type setting and the associated setting on the client PC. I tried all of the various settings (should be 100 MBit/Full Duplex), but nothing works.

    Does anybody have any ideas at what else to look for? Thanks

    Might try this:

    Speed up network (LAN) browsing in Win2K/XP
    Open the Registry Editor (REGEDIT.EXE)

    Rename the following registry entry:
    HKEY_LOCAL_MACHINE
    \Software
    \Microsoft
    \Windows
    \CurrentVersion
    \Explorer
    \RemoteComputer
    \Namespace
    \{D6277990-4C6A-11CF-8D87-00AA0060F5BF}

    For example, you can rename it to:

    DISABLED {xxD6277990-4C6A-11CF-8D87-00AA0060F5BF}

    This change prevents the browsing computer from checking for scheduled tasks on the remote machine before connecting, which is apparently the reason for the slowness.
