I've been trying to diagnose slow logins to my domain. One of my first stops was Domain login very slow 10+ minutes.
So far I've been able to tell it has to do with my policy that applies folder redirection and administratively assigns offline files. Enabling this policy reliably adds from 30 - 90 seconds to the login.
This happens even on profiles that only have 20 megabytes in the redirected folders.
I went through a number of articles including suggestions of using procmon to see if a hangup is occurring. I did find and fix a few second hangup on an old scheduled task, but nothing near explaining this long of a lag.
I also looked at a couple of the active installer suggestions - such as the mail app.
What else can / should I check out before I break out Wireshark?
Edit for the questions:
- This is occurring every log on. Software settings / etc persist as they should. There are no temporary, mandatory, etc profiles in the mix.
- I see activity via procmon, but nothing that indicates a gap. No gaps event times, no processes with extended duration.
- I previously turned up the verbosity on the file redirection logs. Based on the folder redirection operational logs it takes under 1 second for the policy to process (event 1000 to event 1001)
- The group policy operational log shows a couple of my more complex policies clocking in at about 1 second each.
