SYMPTOMS

Consider the following scenario:
  • On a computer that is running Microsoft Windows XP with Service Pack 2 or that is running Microsoft Windows Server 2003 with Service Pack 1, you install more than three programs that are related to file security. For example, you install more than three antivirus programs or file-encryption programs.
  • The computer is part of a domain.
In this scenario, when you try to log on to the domain, you may receive a Stop error message that is similar to the following:
STOP 0x00000035 (0x8207ecd8, 0x00000000, 0x00000000, 0x00000000) NO_MORE_IRP_STACK_LOCATIONS
Note The first parameter in this error message may vary.

CAUSE

This problem occurs because the Mup.sys driver assumes that there must be no more than three file-system filter drivers running at the same time. The Mup.sys driver handles Distributed File System (DFS) file I/O requests. If there are four or more file system filter drivers, the I/O request packet (IRP) location buffer that is pre-allocated by Mup.sys will overflow. When this occurs, you receive the Stop error that is described in the Symptoms section.
