Taarik,
Several things can cause this issue. If you have run generic WMI test either via command line or wbemtest then you know it is a basic WMI issue. Try the following:
1. Validate you can RDP to the host from the Mid-Server to the problem host using your credentials. If this is this works you know your credentials are good. I think you have tried this, but want to validate. If this doesn't work you know your issue. If it does go to Step 2.
2. RDP to Mid-Server and run the following command line and see if you get connected:
- wmic /node:"TARGET IP Address" /user:"YOURDOMAIN/YOURUSERNAME" /password:"YOUR PASSWORD" path win32_operatingsystem
3. If this does not work, verify the following:
- RPC and WMI Windows Services are enabled
- Others have gotten this issue when time difference between Mid-Server and Discovered machines are vastly different. Check to make sure that machines are fairly to same time.
- Check Windows Firewall is set to allow WMI. Here is a link to this: Configuring the Firewall to Allow wmic | Windows 7 Portable Command Guide: Understanding the Windows...
Check these things and see if this resolves your issue
