Continuing on from my previous post, we were still having certain users with logons in the dozens of seconds to minutes. I wanted to find out why and see if there is anything further that could be done.
After identifying a user with a long logon with ControlUp I ran the ‘Analyze Logon Duration’ script:
Jeez, 59.4 seconds to logon with 51.2 seconds of that spent on the User Profile portion. What is going on? I turned to process monitor to capture the logon process:
Well, there appears to be a 1 minute gap between the cmd.exe command from when WinLogon.exe starts it. The stage it ‘freezes’ at is “Please wait for the user profile service”.
Since there is no data recorded by Process Monitor I tested by deleting the users profile. It made no difference, still 60 seconds. But, since I now know it’s not the user profile it must be something else. Experience has taught me to blame the user object and look for network paths. 50 seconds or so just *feels* like a network timeout. So I examined the users AD object:
Well well well, we have a path. Is it valid?
It is not valid. So is my suspicion correct? I removed the Home Directory path and relaunched:
Well that’s much, much better!
So now I want ControlUp to identify this potential issue. Unfortunately, I don’t really see any events I can key in on that says ‘Attempting to map home drive’. But what we can do is pull that AD attribute and test to see if it’s valid and let us know if it’s not. This is the output I now generate:
I revised the messaging slightly as I’ve found the ‘Group Policy’ phase can be affected if GPP Drive Maps reference the home directory attribute as well.
So I took my previous script and updated it further. This time with a check for valid home directories. I also added some window sizing information to give greater width for the response as ‘Interim Delay’ was getting truncated when there were long printer names. Here is the further updated script:
