    NT4 to Windows 2008 Speed Issues (Windows Server 2008)

    Hi, might be a bit vague in describing the issue but hopefully somebody can give us some pointers.

    Got 2 sites and recently swapped an old NT4 server for a sparkly new Windows 2008 device, copied all shared files across and made sure all permissions on the the new box were as before.

    Local users at site A can access Excel files shared on the new box without a problem but users at site B now have to wait up to 45 seconds for files to open as opposed to the 2 or 3 seconds previously when accessing the NT4 box. As a test, we fired up the old box and files on the old NT4 box open almost immediately. Are we missing something? Does something need to be "switched on"? I'm at a loss to explain to my FD why replacing an 8 year old machine with a new box 10 times as powerful has made things slower!

    What client operating system? Is this via a VPN, RDP, or Citrix? How is the network configured? What server roles are defined?

    Also, see Configuring Windows Server 2008 File Sharing - Techotopia to double check your configuration.

    The issues seem to have disappeared using Vista as a client after making this change to the Windows 2008 server:

    Steps to disable Raw SMBs on the server:

    1. Run Registry Editor (REGEDT32.EXE)
    2. Go to the following key:
    HKEY_LOCAL_MACHINE SYSTEMCurrentControlSetServicesLanmanServerParamet ers
    3. From the Edit menu choose Add Value
    4. Add the following:
    Value Name: EnableRaw
    Data Type: REG_DWORD
    Data: 0

    That solved that issue however XP client machines still struggle. Ensuring SP2 was installed improved performance from about 30 seconds to 20 seconds but it's still not good. Sticking SP3 on made no improvement on speed either <img src=/S/brickwall.gif border=0 alt=brickwall width=25 height=15>

    Hi Joe, thanks for your suggestion. Gave it a try but no difference. Still 20 seconds to open a file <img src=/S/sorry.gif border=0 alt=sorry width=15 height=15>

    Do all of the troubled PCs have the same network card? Are the drivers up-to-date?
