"Please Wait" hangs on startup- Machine on AD

Hi guys new to the forum and was hoping somebody could chime in with some more info regarding an odd issue some computers were having at my workplace.

Background Info: Dell laptops (E6420,E6410,XPS), Windows 7 Enterprise 64bit, Connected to AD

The laptops are intermittenly hanging at the "Please Wait" screen right before the alt + ctrl + Delete option appears. The time it hangs varies. Sometimes it can hang for 2 minutes, sometimes it could hang for an hour. So far the only pattern we could find is that it happens mainly while the computers are not connected wired to the LAN and on wireless. If we toggle the wifi off during the please wait, a few seconds-mins later it finally shows the option to login. I set the NLA service to manual startup (network list service was already set to manual as well), and it stopped doing it. I enable it, and it starts hanging on message again. It also works fine in safe mode (both networking and without).

Any suggestions or ideas? Would leaving the NLA service to manual cause any major conflicts? Are there any timeout settings we could verify?

Thanks and appreciate any input given.

My best guess is to run this hot fix

High CPU usage or a lengthy startup process occurs during WMI repository verification when a large WMI repository exists in Windows 7 or in Windows Server 2008 R2

Or http://support.microsoft.com/kb/2617858

Here are other hot fixes for the WMI process as well

If the hotfix Fabertech suggested doesn't solve the issue. You might want to capture the processes during startup using Process Monitor - part of Windows Sysinternals. This won't fix anything, but it will tell you what's going on.

Slartybart, good eye for troubleshooting

Thanks a bunch FaberTech and Slartybart. Did the hotfix now and at least on my machine the please wait dissapears faster. Would you happen to know how long the message is supposed to show (if it even is supposed to have a delay)? Im running process monitor now. Thanks again super fast replies

Jzlo,

I don't know what you should expect for the delay - relatively short though. I would venture < 1 minute. Glad to hear the hotfix worked. Please post which ones you applied and which ones worked or had no affect. If you only did the first one, cool - let others know.

If you want, give Fabertech a tip (+rep), since he pointed you to the fix.

Hmm seems its taking long again to boot now. Tomorrow i will continue to test the different hotfixes and see if i can make any sense of the boot logging from process monitor. One thing is for sure, with the NLA service set to manual the please wait dissapears within 6 seconds. Thanks again for the help guys.

A few people had different ways of solving there problem in this thread.

Boot up hangs at "Please wait" for "ever". NLA Service is culprit.

Solved then?
