Check both the server and the client's event logs for any suspicious entries that might suggest what is misconfigured. Also, check what are the identities of Visual Studio and the app that calls WMI and if they are not the same, what's the difference in their security configuration.

The culprit is simply the netbios name.. Prior to re-build the computer name was 'rulestream' After re-built some how it is given 'rulestream.myDomain.com' I was able to spot the difference using Sysinternals TcpView.. Thanks Sysinternals
