SYMPTOMS
If you apply an Exchange Server 5.5 service pack, error messages may be displayed that state that the following files are in use and cannot be updated:
- Gwperf.dll
- Imsperf.dll
- Mdbperf.dll
- Mseperf.dll
- Mtaperf.dll
- Eseperf.dll
- Edbbcli.dll
When you attempt to start the services after you finish the service pack installation, the directory information store does not start and generates the following error message:
CAUSE
All of the *perf.dll files listed in the "Symptoms" section of this article are Performance Monitor support dynamic-link libraries (DLLs). This problem can occur because the Exchange Server service pack installer determines if these DLLs have been opened by a process, but the installer does not determine if the files are locked. The service pack installer generates a message that prompts you with three choices: Ignore, Retry, or Abort. If you select Ignore, the file versions of these DLLs and the new service pack executable files (Dsamain.exe, Store.exe, and so on) are copied to the server, which creates a mismatch in the version numbers of DLLs and .exe files. The Dsamain service does not start and the following error message is generated:
WORKAROUND
To work around this problem:
- Stop all of the unnecessary services on the server, as well as any local or remote copies of Performance Monitor that may be running against the server. If the Edbbcli.dll file is listed as a file that cannot be updated in the error message that is displayed, make sure that no backup software is loaded or running, and also make sure that no backup agents are running on the server. Edbbcli is the Exchange Server database backup client that allows for online backups of the Exchange Server database.
- Run the service pack update again. There is a delay of several minutes while the Directory service attempts to start. The Directory service cannot start and the following error message is displayed: Click OK, and then continue with the service pack installation.
- When an error message is displayed that lists the files that were skipped in the original service pack installation (*perf.dll), do not click Ignore, Retry, or Abort. With the service pack installation still running, press CTRL+ESC, and then start Windows Explorer. Go to the DLL that cannot be updated (typically the path to the file is either Exchsrvr\Bin or Winnt\System32) and rename the *perf.dll file to *perf.old.
- Minimize Windows Explorer, and then click Retry in the service pack installation. You need to repeat this process for each DLL that is displayed in an error message during the service pack installation.
After you finish these installation steps, run the service pack installation again and make sure that it finishes without error messages to make sure that the service pack has been applied correctly.
