I was able to succesfully connect using wbemtest.exe
i verified that DCOM is set "enable Distributed COM"
This works on other servers just fine.
Sorry for the delayed reply; I wanted to make sure we closed the loop on this with you. This doesn't sound like a bug. It sounds more like a bad WMI connection to the client system, the cause typically being the necessary ruleset(s) hasn't been enabled on Windows Firewall. Hope this helps.
