Cannot Log Into Windchill

[ScottJohnson]

We have one person that can only access Windchill part of the time, when no one else in the Engineering group has an issue. The IT group has no clue, and we have tried almost everything. He tries to log in and the local access sign in just keeps popping back up. Any ideas or where we can see log in errors or rejection?

Start with the httpserver error.log.

Site > utilities > server status > monitoring > log file viewer. tick wt.webserver.logs.dir and click ok, then you should see an error.log and access.log at least

What can I look for at the lower level?
