I am trying to troubleshoot an issue where it takes a very long time (4-5 minutes) for users to log on to their computers on a network, and after catching this timeline with the Windows Performance Analyzer, I was wondering why there is a 203 second gap from where nothing seems to be running. Here is a screenshot of what I'm talking about.
The gap I'm talking about is from 220 to 420, where nothing seems to be happening. What would be a cause of this? My guess is that things like GPClient and SessionEnv might be crashing, because they seem to start, stop, and start again. I could not find too much info about what these items do on Google, and I have never dealt with this issue before. We do have a few Group Policies on the network when you log in, but those seem to be taking a normal amount of time. I'm concerned with that 200 second gap. Any ideas? Thank you!
