I have a small set up 4 XP computers, 1 Windows 7, and one server 2003. The only issue with adding WMI sensors is on the Windows XP boxes. I have enabled DCOM, verified the WMI registry entries, local securoty policy is allowing network access.
Could there be anything I am missing in PRTG?
This is a workgroup I tried the computer name:user:password and localhost:username:password in the prtg settings.
