Hi, I have about 200+ workstation with Windows 7 Prof, which are joined to 2003 domain. Sometimes I observe that LogonUI stop at welcome screen. The Screen Freeze but mouse still work and Blue animation cursor still spin around. The problem is totally random, when people login to domain. In most case people can login to workstation after computer hard restart. I've tried to: · use clean boot · remove all group police object from computers' organization unit · turn on via registry "Show logon verbose message" - In normal situation computer show welcome screen and next change the text to: wait for user profile service, applying group policy, etc. When computer hang up logonui.exe still stop at a welcome text. · at DCs and local security event logs I didn't see any user logon event · I have analyzed all computer event logs and didn't find nothing special:/ No warnning, error or strange information events. I want to turn on user environment debug at logon, but is quite difficult to turn it on via gpo on all computers.

Hi, Thanks for posting in Microsoft TechNet forums. You can check if this issue occur when you enter Safe Mode with networking. It can troubleshoot if there’s any driver problems. Then open the Event Viewer – Applications and Services – Microsoft – Windows – Diagnostics-Performance – Operational, Under this, find the related time event logs, Task Category could be Boot Performance Monitor, then click Details. You can figure out which process took a long time or hang during the boot. Best Regards, Miya Yao TechNet Subscriber Support in forum.

Hi, Last weeks I had very limited access to Internet, so I wasn't able to check this forum. The problem is still unsolved. As I wrote "problem is random" so I can't boot all computers from Safe Mode. Drivers should be ok, because we had 5 different hardware configuration and this problem appears on all five hardware type. Regards, Karol

Hi, Please follow my former reply, check the Event Viewer, navigate to :Applications and Services Logs – Microsoft – Windows – Diagnostics-Performance-Operational Find the Task Category: Boot Performance Monitoring, Event ID 100 Check the details to find which freeze.

I will check this today.

We are suffering through a similar experience here with some of our workstations. It's random. The welcome screen will display for roughly 1 hour before seeing a desktop. Monitoring the processes during this time shows the System process using the majority of the threads. We've tried turning all sorts of services and startup items off with no success. I think this is somehow related to local profiles. We have about 10,000 computers in our organization but the problem is only occurring on some machines in areas where hundreds of different users log on to those PCs. Other areas where only a few different accounts are logging into PCs are not experiencing this issue at all. We are still trying to pinpoint the issue. We are bringing these problem PCs back to our office and trying to find the issue. I'll post an update if we find anything. Any pro suggestions would be greatly appreciated also :)

For anyone interested: We finally found the source of our problem here. It was the amount of local profiles on the machine. We didn't have this problem in XP, but it seems to be an issue with Windows 7. Once we start getting to around 250+ local profiles the profscv just hangs when trying to log on to the domain. The short term solution is to just delete all the old profiles from the machines. We are still looking for a long term solution.

Hi, I'm using mandatory profile and I've set up "Clear mandatory profile after logout" but problem still exists:/ Do you have any other idea? @Miya Yao - In Performance-Operational I don't see any special events when logonui hung on "Welcome screen" Karol PS I could be correlated with many different users logon to one PC, I will check this.

Delays in WinLogon phase can be caused by hanging services, group policies or connecting network drives. Follow my guide [1] to make a boot trace and compress the boot_BASE+CSWITCH+DRIVERS+POWER_1.etl as 7z or RAR and upload it to your Skydrive [2] and post the link here. I take a look at the trace, maybe I see what's wrong with your Windows.

Hi, I will catch this trace ASAP. In Diagnostic-DPS log I've found many inform: Diagnostic module {15fba3b8-a37a-4f91-bdba-fbb98fe804bf} (%SystemRoot%\system32\diagperf.dll) encountered an error while handling scenario {2698178d-fdad-40ae-9d3c-1371703adc5b}, instance {979be528-8b91-4b92-bc7c-8c115b615c5b}, original activity ID {2698178d-fdad-40ae-9d3c-1371703adc5b}. On many diffreent computers log event are similar only instance CSID: {979be528-8b91-4b92-bc7c-8c115b615c5b} is different.

Hi all, We're having the same problem, but with Windows 7 Enterprise Edition on 400+ PCs in our organisation. Similar issues: - very slow logon at Welcome Screen - problem is random - logon time at Welcome Screen gets progressively worse; could be 10 minutes one day, 15 minutes the next and so on. Has gotten as bad as 1 hour plus. We thought the problem was with the profiles also, because we pulled down clean images from our WDS server and it would log on fine. But lately we've found the slow log on problem on PCs with under 10 profiles. So that ruled that theory out for us. Earlier this week, when the machines booted up after a powercut some were taking longer than an hour to log in. We had to use our MSCONFIG temporary fix. The MSCONFIG temporary fix we use is booting into Safe Mode, running MSCONFIG and selecting Diagnostic Startup. Click on the Services tab and click Enable All. Click on the Startup tab and enable the following four startup items - Logitech SetPoint, Windows Sidebar, Microsoft Office 2010 and Microsoft Forefront. Essentially what we're doing here is turning off and on the services. And turning off and on the startup items that were already enabled - so we're not changing anything really. But this seems to fix the problem temporarily. It seems that any adjustment to the MSCONFIG (even if you disable and re-enable all the same settings without a re-boot) will fix the problem - but only temporarily. We've had this problem for months now - has anyone found a solution to this problem yet???

also make an xbootmgr trace, please."A programmer is just a tool which converts caffeine into code" CLIP- Stellvertreter http://www.winvistaside.de/
