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.

Re: Desktop heap - CsrSrvSharedSectionBase invalid

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...

Re: Desktop heap - CsrSrvSharedSectionBase invalid

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]
