Thanks; yes, I've done all that. Googling suggests a possible firewall issue, but I don't want to get the networks team involved if I can help it.

I can run perfmon fine on the server itself; is there any reason I should NOT do this? Brent's tutorial specifies not to, but not why- and also it is 7 years old so things may have changed. If I can run it on the server then that solves my immediate problems.

Thanks again.
