I am tagging onto this post because my situation is very similar to what sky2830 described but a bit different.
I also have a group of Windows 2003 Servers (actually Windows 2003 Standard SP2). In my case some are successfully being polled from NPM using WMI, thanks to assistance from aLTeReGo as well, but 3 others I am having difficulty with. I can use wbemtest to connect either from my NPM server to the servers being successfully polled by NPM but not to the other 3. The error I get on those 3 is "Access is denied."
These 2003 servers are all on a remote site to the NPM server so to be safe, I tried going from one of the successfully polled servers to the failing servers and get the same "Access is denied." error in wbemtest. I have double, triple, quadruple checked the Administrator creds I am using and can log onto the 3 servers using those creds.
My next test was to get onto each of the 3 and try attaching to themselves using wbemtest which was successful. I then tried from the 3 to connect to the successfully polled servers using wbemtest and get "Access is denied." going that opposite direction as well. I finally tried connecting from one failing server to the other failing servers using wbemtest and, you probably guessed it, "Access is denied."
I have compared settings for permissions at the user and WMI levels and all failing match with the successful servers. I also read SolarWinds Knowledge Base :: How to create a non-administrator user for APM polling. hoping that might lead me to something but again all matched between the failing and successful servers.
Any ideas?
THANKS
Mike
