RESOLUTIONWarningThis workaround may make your computer or your network more vulnerable to attack by malicious users or by malicious software such as viruses. We do not recommend this workaround but are providing this information so that you can implement this workaround at your own discretion. Use this workaround at your own risk.WARNING: If you use Registry Editor incorrectly, you may cause serious problems that may require you to reinstall your operating system. Microsoft cannot guarantee that you can solve problems that result from using Registry Editor incorrectly. Use Registry Editor at your own risk.
You can increase the IRPStackSize value. You must first add this value to the following key if it is not already present:
Value Name: IRPStackSize
Data Type: DWORD
Increasing this value requires some memory from the non-allocated memory pool, but the impact should not be noticeable.
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. http://support.micro...kb/225782/en-us
