SYMPTOMS
When you upgrade to Exchange Server 5.5, the upgrade fails and the
following error message appears:
System could not find the path specified (0xC0020003)
This occurs immediately after the option to upgrade or uninstall Exchange.
CAUSE
The Key Management (KM) server was not removed completely during a previous
upgrade attempt.
WORKAROUNDWARNING: If you use Registry Editor incorrectly, you may cause serious problems that may
require you to reinstall your operating system. Microsoft cannot guarantee that you can solve
problems that result from using Registry Editor incorrectly. Use Registry Editor at your own
risk.
To work around this problem, the registry key responsible for the KM
service, MSExchangeKMS, must be deleted. To do this:
- Start Registry Editor (Regedt32.exe) and navigate to the following registry subtree:
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\MSExchangeKMS - From the Edit menu, click Delete.
- Click OK, and then quit the Registry Editor.
- Restart the server for the registry changes to take effect.
MORE INFORMATION
This workaround allows Exchange Server 5.5 to upgrade the existing server.
To regain the functionality of the Key Management server, the KM server
must be reinstalled.
