SOLVED: nvraid network sharing problem

I was having a hell of a time trying to share folders on a mirrored RAID 1 array over a simple xp network. Sharing folders on other drives worked fine. The error I would receive was:

You might not have permission to use this network resource. Contact the administrator of this server to find out if you have access permissions.

Not enough server storage is available to process this command.


After much wasted time I found it was related to NVRAID and a setting in the registry called IRPStackSize

When I increased its dword decimal value to 25 it fixed the problem.

HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\LanmanServer\Parameters

double-click the IRPStackSize value.

If the IRPStackSize value does not already exist, use the following procedure to create it:
a. In the Parameters folder of the registry, right-click the right pane.
b. Point to New, and then click DWord Value.
c. Type IRPStackSize.

set decimal value to 25.

restart computer after change is made.
