All of a sudden today, I am receiving the above error when trying to open System Manager. Has anyone seen this before and know what causes it?
Do you have a different version of polling engine on the named server?
Not that I am aware of. It was working fine before and nothing has changed.
It may be worth mentioning that this was originally installed as 8.5 and we performed an upgrade to 9.0 SP1 about 2 months ago. There were no issues with that until now.
It could just be an anomaly perhaps. Try running through the configuration wizard to refresh things.
I just did that and now I get a "Can not connect to servername" error.
