- Locate the following key in the registry:
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\MSExchangeIM\Performance
- Click the Performance subkey, and then click Permissions from the Security menu.
- Verify that System, Administrators, and the account that you are logged on with have Full Control permissions.
- Stop the IIS Admin Service. To do so:
- At a command prompt, type net stop iisadmin.
- When you stop the IIS Admin Service, the following services are also stopped:
