The Microsoft® Exchange Server Analyzer Tool uses remote procedure calls (RPCs) to read the CurrentVersion string value from the following registry key on the Active Directory® directory server:
HKEY_LOCAL_MACHINE\Software\Microsoft\Windows NT\CurrentVersion\CurrentVersion
On a computer running Microsoft Windows® 2000 Server, the expected value for the CurrentVersion string is 5.0. On a computer running Windows Server™ 2003, the expected value is 5.2.
If the Exchange Server Analyzer cannot read this registry value for any reason, an error is displayed.
To correct this
error
-
Ensure that the directory server has been started and is connected to the network.
-
Use the PING command to determine if the directory server is reachable.
-
If there is a firewall in place, check to see if RPC ports are blocked.
-
Ensure that the Remote Registry service on the directory server has been started.
-
Check the permissions for the account under which the Exchange Server Analyzer is running to ensure that it has sufficient permissions to read the registry on the Active Directory server.
