Symptoms

Consider the following scenario:

  • On a computer that is running Microsoft Windows XP with Service Pack 2 (SP2), Microsoft Windows XP with Service Pack 3 (SP3), Microsoft Windows Server 2003 with Service Pack 1 (SP1), or Microsoft Windows Server 2003 with Service Pack 2 (SP2), 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.
