Solution:

In my case the issue is with DCOM configuration access settings, here is how to fix it,

1. From the Start menu, click Run and type Dcomcnfg.exe.
2. In Component Services, click Console root, expand Component Services, expand Computers, and then click My Computer. On the Action menu, click Properties.
3. In the My Computer Properties dialog box, on the COM Security tab, in the Access Permissions section, click Edit Default.
4. In the Group or user names dialog box, check if Local Administrator is present or not, or the group you need access to, if not present then click Add.
5. In the Select User, Computers, or Groups dialog box, in the Enter the object names to select (examples): box, type Administrator and click OK (Note: In From This Location: click Locations and select the local computer instead of domain)
6. In the Permissions for Administrators section, select the check box to allow Local Access.
7. Click OK twice, and then close Computer Management.

Try to run WMI again, it should work fine, if not, then try to give remote access to administrators. In case everything looks perfect then troubleshoot further.
