I have a Windows 7 Enterprise (sp1) image I "ghosted" out to multiple machines. During the set up process each system gets a unique Computer name and joins a domain. All systems share a common AD user name and AD is set to allow that user name to have unlimited access. There is nothing special about the image and the software packages (MS Office 2010, Adobe CS3, Firefox and the only weird software I use is Deep Freeze, but I have the issue on systems that I have not yet installed Deep Freeze on so that sort of rules that out. There is no special equipment or externals, in fact all hardware is identical (Dell 745's with 4 GB Ram, 200GB HD) On any given day, when I arrive to the lab, an average of 6 computers will be sitting at the "Welcome" screen. It is completely random which systems have the issue. One computer today that is affected will not have the issue tomorrow. I have the BIOS set to power the computers on in a staggered fashion 1 minute apart so that the DC is not hammered with 30 requests all at once. Its never been an issue before my migration to Windows 7. I have to force power off the affected systems and restart them. Sometimes they will boot properly. Sometimes I will be forced to power cycle again. Occasionally I will be able to hit CTRL ALT DLT  during the first 30 seconds after the "Welcome" screen appears and that allows me to get to that control screen and then I select cancel and it boots to desk top. Other times CTRL ALT DLT does not get to the control screen so I continue with the power cycle. I've read a lot of people with this similar issue but none of the solutions seem to be working for them or they are not suited for their actual issue. Booting into Safe mode and doing a system restore is not a solution, especially since it has always done this so there is no past date that I could use anyway and the fact that it is random and systems work one day and then not the next tells me that the image isn't exactly the problem (though it certainly could be). System logs show nothing out of the ordinary. And yes I can boot in to local administrator profile without issue. I've deleted the user account from AD and recreated it and then re-imaged the systems but the issues continues. The image does NOT have the user profile on it until I join it to the domain so there is no residual profile information from an older version of said user account. Help or direction would be much appreciated.

Have you attempted booting into Safe mode w/networking to see if it is a broken driver? It seems a lot of people have the issue. Could it be your SID? It really shouldn't be the issue, but at this point if you are going insane I would do a clean install and see where that gets you.

Please open Event Log, locate to Application and Service Logs-Microsoft-Windows-Diagnostics-Performance/Operational, check events whose ID is 100. You will get the detail tracks of the boot process. Try to find the reason. I suspect that there are incompatible programs. If any startup program is the root cause, troubleshoot in Clean Boot Mode.Please remember to click Mark as Answer on the post that helps you, and to click Unmark as Answer if a marked post does not actually answer your question.

Are you still having this issue? We are also having this issue with almost the same setup. Any solution would help. Thanks, BD
