The Microsoft® Exchange Server Analyzer Tool queries the Win32_ComputerSystem Microsoft Windows® Management Instrumentation (WMI) class to determine whether a value is set for the Name key. If the WMI query fails, and the Exchange Server is not running on Microsoft Windows NT® Server°4.0, the Exchange Server Analyzer displays an error.
There are two likely causes for this error:
- The account that runs the Exchange Server Analyzer does not
have sufficient permissions to query WMI classes.
- A network issue is preventing the Exchange Server Analyzer from
contacting the computer.
Make sure 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, check to see if remote procedure call (RPC) ports are blocked.
Examine the permissions for the account under which the Exchange Server Analyzer is running. The account under which the Exchange Server Analyzer is running must have local Administrator permissions on each Exchange server that it is scanning.
Alternatively, you can grant specific WMI permission to the account under which the Exchange Server Analyzer is running:
- On the Exchange computer, open the Computer Management
Microsoft Management Console (MMC) tree.
- Under Services and Applications, right-click WMI
Control, and then click Properties.
- On the WMI Controls Property page, click the
Security tab, and then expand Root.
- Select the CIMV2 folder, and click Security.
- On the Security for ROOT\CIMV2 page, add the account
under which the Exchange Server Analyzer runs.
- On the Exchange computer, open the Computer Management Microsoft Management Console (MMC) tree.
Select the account that you added in Step 5 above. In Permissions for Selected_Account, under the Allow column, select both Remote Enable and Read Security, and then click OK.
