The Microsoft® Exchange Server Analyzer Tool uses remote procedure calls (RPCs) to read the CurrentVersion string value from the following registry key on the Exchange Server computer:
If the Exchange Server Analyzer cannot read this registry value for any reason, an error is displayed.
To correct this error
Ensure that the Exchange Server computer has been started and is connected to the network.
Use the Ping command to see if the Exchange Server computer 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 Exchange Server computer has been started.
Check the permissions for the account under which the Exchange Server Analyzer Tool is running to ensure that it has sufficient permissions to read the registry on the Exchange Server computer.
Note: By default, the Exchange Server Analyzer will make this connection attempt using the currently logged in account. If this connection attempt is being made from either of the following configurations, the logged on credentials for the computers must be identical:
• A workgroup based computer that has the Exchange Edge server role installed, to a domain based computer that has Exchange server roles installed.
• A domain based computer that has Exchange server roles installed to a workgroup based computer that has the Exchange Edge server role installed.
Verify the "Server Service" is enabled and running on the Exchange Server computer.
Verify "File and Printer Sharing for Microsoft Networks" is selected fortthe properties of the relevant Network Interface Card (NIC).
