A stop error occurs when you have installed many programs that use filter drivers in Windows 2000 (327632)

CAUSE

This problem may occur when you have installed two or more programs that use filter drivers. Typically, you experience this problem when you have an antivirus program that is running a form of real-time protection. However, this problem does not occur only with antivirus programs.

After the Ntfs.sys driver creates an object, the driver determines the remaining size of the stack. When you have two or more filter drivers that are running, the stack size of the Ntfs.sys driver decreases rapidly. When the Ntfs.sys driver tries to create a new object, and there is not sufficient stack space available, a stack overflow occurs and causes a stop error.
