Err Msg: Stop 0x0000007f (Unexpected_ Kernel_ Mode_ Trap)

• Microsoft Windows NT Server version 3.51

SYMPTOMS

When you run Windows NT Server version 3.51 with Service Pack 4 or Service Pack 5 installed, you may receive the following error message:

Stop 0x0000007f (Unexpected_ Kernel_ Mode_ Trap)

CAUSE

This error message can occur if you have McAfee NetShield version 2.5.2 or version 2.5.3 installed on your computer. The McAfee drivers exhaust the kernel mode stack. The kernel mode stack is an important kernel mode resource. This can occur when many local variables are being defined in the functions and those variables are consuming a lot of memory off the stack.

RESOLUTION

To resolve this issue, contact McAfee to inquire about a possible update to address this issue.

To work around this issue, disable McAfee services, and then uninstall McAfee NetShield. For information about how to uninstall McAfee NetShield, contact McAfee Technical Support.
