SYMPTOMS
When you attempt to upgrade to Microsoft Exchange Server version 5.0, you may receive the following error message:

The file C:\EXCHSRVR\CONNECT\MSMCON\BIN\MTPERF.DLL

is in use by another application.

You then have the options to Abort, Retry, or Ignore. If you click Ignore, you may receive similar error messages, but for different files. Such files may be:

C:\EXCHSRVR\CONNECT\MSMCON\BIN\XTNPERF.DLL

C:\EXCHSRVR\BIN\MDBPERF.DLL

C:\EXCHSRVR\BIN\MTAPERF.DLL

C:\EXCHSRVR\BIN\GWPERF.DLL

C:\EXCHSRVR\BIN\IMCPERF.DLL



CAUSE
If any of the above files are locked open by other applications, such as virus checking programs, Simple Network Management Protocol (SNMP) programs, or Performance Monitor (which may be running remotely against the Exchange Server computer), then the upgrade process cannot replace these files.



WORKAROUND
To work around this problem, temporarily stop the program (usually by stopping the corresponding service in the Windows NT Control Panel Services applet) that may be locking the DLL open. Click the Retry option and continue with setup. After setup completes successfully, restart any services you stopped in the Windows NT Control Panel Services applet.
