Question : How to Disable Read Caching on Windows XP Pro workstations

I have an ISAM database running on Windows Server 2003.

In order to avoid various locking and corruption issues I have disabled Op Locks, etc. on the servers following normally recommended guidelines.

However, on the workstations the guidelines state that read caching should be disabled using the following registry key:

---------------------------------
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\VxD\VREDIR

DiscardCacheOnOpen REG_BINARY 0 or 1
Default: 0 (not disabled)

To disable read caching, the value of DiscardCacheOnOpen must be set to 1.
------------------------------------

However, on all of the Windows XP Pro workstations I have checked this key (starting with the VxD portion) does not exist.

I'm looking for confirmation that this is the right key for Windows XP or for the proper key if there is another.

Thanks in advance,

Tim

That reg key is only for pre-nt workstations..  you should not have to enable it for XP....
