Dear,

As in the following blog post : viewtopic.php?f=32&t=53505

I've troubles to connect to the web client when using windows authentication.

Here are the messages I get:



And after refresh:



Here is what appears in the Application event viewer:

I've tried the following:

Complete reinstall of IIS, NAV Web Client, whole NAV features.
Rebuild of Performance counters
Edit registry to allow access to performance counters

It sure has something to do with the fact that I use windows logins (permissions missing?)

Thanks for your help

Just solved the error by adding the Guest group to the Performance Monitor User group.

Now it works like a charm!

Edit: now it's not working again

If I add a single windows login to the Perf Monitor Users group it works..

Ok so to solve this issue I added "Domain Users" group to the "Perf Monitor Users" group.

I'll investigate with the people managing the domain if it could cause any security concerns but this is the only workable solution I found so far.

Same error, but after an update of server (2008R2).
I resolve it adding Network service to Performance Monitor Users group.
