Windows XP Hangs After Logon "Personalizing Internet Explorer" (Custom Shell)

 

I work for an OEM that uses a Windows XP system to control a piece of

manufacturing equipment. During system setup we change the default system

shell (HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon\Shell) to

our user interface application (A .NET 2.0 Application)

 

When customers logon to the system with a new account (i.e. a new user, one

that has never been used), 1 out of about 10 times the "Personalized

Settings" window appears (upper left corner of the screen) and stops at

Internet Explorer. In some cases we've waited upto 2 hours, and the shell

never starts. We primarily have IE6 installed, but in atleast one case we've

had IE7, it also happened more often with SP2. The equipment has to be power

cycled to recover from the problem.

 

Has anyone else seen this? Anyone have any ideas about how we can debug

this?
