I think you can get the same level of detail:- Value Path: HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Diagnostics Value Name: GPSvcDebugLevel Value Type: REG_DWORD Value Data: 30002 (hex) Output: %windir%\debug\usermode\gpsvc.log That might give a bit more insight From: thin-bounce@xxxxxxxxxxxxx [mailto:thin-bounce@xxxxxxxxxxxxx] On Behalf Of Anthony Green Sent: 08 January 2010 11:37 To: thin@xxxxxxxxxxxxx Subject: [THIN] Re: 2008 vs 2003 login times Theres some group policy information in the eventlog but nothing like the userenv debugging you got with 2k3. Ive tried turning all group policies off which didn't really make a difference. I seemed to get better performance when disabling client mappings, especially printer mappings, but nothing to shout about. Am I gonna have to accept this and just say "Sorry, thats 2008 for ya, weve upgraded you to the latest OS and given you a slower, but much more reliable logon" Thanks, Ant.

Did you do some load testing before your role out? You could do a logon trace - maybe look at the timings ? if you've still got a w2k3 box you could run a userenv.log trace w2k8 sticks the trace into the event log iirc. Maybe there's a registry/script change/update that's hosing the logon?

One company went from 7 secs to 14 secs (i know it's not a long login time but it has doubled!). We basically replicated their Windows 2003 setup (xenapp\DCs\File\Print\SQL) but have everything on Windows 2008. Most things work ok but the login times are killing me, I'm having to explain why this is without really knowing why there is such a difference. Anyone else notice this? Any tips? Thanks, Ant.
