APPLIES TO
- Microsoft Exchange Server 5.0 Standard Edition
This article was previously published under Q167635
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.
