WMI Problem in opmanager

Hi Team

We are working on a customer site and we face this strange problem.

We are using WMI on most of the systems and we use the WMITEST.exe file for testing the WMI working or not. It gives output in the wmitest, but when we use in opmanager, it fails WMI - Test Credentials.From the forums, we tried the vb script option to give the username and password and domain and it fails with

Error # The RPC server is unavailable.

Error # Object required
E:ManageEngineOpManagerconfapplicationscriptscpu.vbs(56, 1) Microsoft VBSc
ript runtime error: Object not a collection

Why does WMITEST work but our vbscript fails ?

We have uploaded logs and screenshot as well for help
