Server randomly drops all connections, system log records multiple instances of Event ID 2000

At random intervals, the server may drop all connections, and no new connections can be established. Administrators can log on to the local computer, but Server Manager is not displayed correctly. Multiple instances of Event ID 2000 may be recorded in the System event log with this error message:

After you install Windows Server 2003 SP1 and Microsoft Security Update MS05-027, you may notice a decrease in performance. You may also notice connectivity issues. Multiple instances of Event ID 2000 may be recorded in the System event log when a Windows client tries to access a network share on the file server:

Event Type: Error
Event Source: Srv
Event Category: None
Event ID: 2000
Description: The server's call to a system service failed unexpectedly. Data Words: 0000: 00040000 00540001 00000000 c00007d0 0010: 00000000 c0000054 00000000 00000000 0020: 00000000 00000000 022a0342

Note The error code c0000054 translates to STATUS_FILE_LOCK_CONFLICT. The second part of the dumpdata 0342 translates to SRV_SVC_MDL_COMPLETE. This indicates the server servcie is actually failing in a "complete MDL write" request.

This behavior can occur when you have an early version of the Cheyenne Open File Agent program installed.

This behavior may also occur because of an outdated version of a third-party kernel-mode file system filter driver (RxFsFltr.sys) of VERITAS Storage Replicator may this problem because. The RxFsFltr.sys file may keep part of the file locked.

To resolve this behavior, obtain and install the latest version of Open File Agent. Alternatively, to resolve this behavior, contact Veritas and obtain and install the latest version of the VERITAS Storage Replicator drivers.

To work around this behavior, remove the Cheyenne Open File Agent program. You can also work around this behavior by removing the VERITAS Storage Replicator program.
