Best practices on a Windows Server 2003 File Server and Failover Cluster File Server

Applies to:

32-bit Windows Server 2003 R2

32-bit Windows Server 2003 Service Pack 2


Many years ago, I wrote the following KB article.

961657 You cannot access the existing File Share resources on a Windows Server 2003 failover cluster 


This is after the fact, to get ahead of the issue, before you deploy, you want to follow every single step in the same KB, so that you don’t run into scalability and performance issues on your Windows Server 2003 and Windows Server 2003 R2.


For 64-bit Windows Server 2003

IA64 Windows Server 2003

The only difference for 64-bit are the following registry keys:

64-bit (x64 and IA-64)



MaxWorkItems (dword) FFFE (hex)

MaxMpxCt (dword) 800 (hex)

MaxRawWorkItems (dword) 200 (hex)

MaxFreeConnections (dword) 1000 (hex)

MinFreeConnections (dword) 100 (hex)


MaxCmds (DWORD) 800 (hex)

HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\Session Manager\Configuration Manager

RegistryLazyFlushInterval (DWORD ) 3C (hex)
