Desktop heap - CsrSrvSharedSectionBase invalid

    Hello.

    On Windows Server 2003 (64-bit) the CsrSrvSharedSectionBase-value in
    [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager
    \SubSystems\CSRSS] is invalid.
    I've seen this on several machines. Not one machine had a valid value.

    Does anyone know why this is?
    What is it used for?
    Is it 32-bit specific?

    How about the Windows-value in [HKEY_LOCAL_MACHINE\SYSTEM
    \CurrentControlSet\Control\Session Manager\SubSystems]? Is that 32-bit
    specific?

    I'm having some problems finding the right value for the SharedSection-
    setting in the Windows-value in [HKEY_LOCAL_MACHINE\SYSTEM
    \CurrentControlSet\Control\Session Manager\SubSystems].
    The default value is '1024,20480,768' but changes don't seem to have
    any effect.

    Does anybody know how much RAM is allocated for the desktop heap on 64-
    bit?

    Thanks
    Mads

    Try this: The registry type may be set incorrectly set to a d-word type, it
    should be set to a q-word type (64-bit value)
    try recreating the value as a Q-word and use the same value.

    The default Desktop Heap for x64 should be 104 meg if I recall properly
    It is documented in this article talking about Terminal Services.

    Thanks, Darrel.

    Do you know what the value should be?
    I have some difficulties seeing what it is.
    It looks like machine code to me...

    Regards
    Mads

  4. Hello Mads,
    I don't have a Windows Server 2003 X64 installation available to me right
    now.
    Running Windows Vista and Windows Server 2008 beta builds sO I don't know
    what the default should be
    Maybe someone else on the newsgroup can report back what their values are
    for that key.
    Thanks,
    Darrell Gorter[MSFT]
