You can increase the IRPStackSize value. You must first add this value to the following key if it is not already present:
HKEY_LOCAL_MACHINE SYSTEM\CurrentControlSet\Services\LanmanServer\ParametersIncreasing this value requires some memory from the non-allocated memory pool, but the impact should not be noticeable.
Value Name: IRPStackSize
Data Type: DWORD
NOTE: It is not always advisable to set the IRPStackSize value to its maximum of 12. Generally, you should start the value at 4 and work your way up, increasing the value by 1 each time. The problem may still occur if the value is too high.
This error message may also occur after installing or uninstalling virus-scanning software. You may want to remove the virus-scanning software or increase the IRPStackSize if you need to use the software.
Microsoft has confirmed that this is a problem in the Microsoft products that are listed at the beginning of this article.
The default IRPStackSize for Windows NT 4.0 SP3 and earlier and Windows NT Terminal Server 4.0 is 4. The default value for SP4 is 11.
