I came across the same issue the other week.
Winsuite AD was installed on my server. I upgraded the server to Winsuite Enterprise Edition, but didn't remove the old Winsuite AD client software from the Client laptops.
On boot up the client laptop came up with the message installing software and shutdown just as you described and then just kept looping round.
I tried everything NDItech suggested, such as manually uninstalling winsuite but nothing worked. In the end I put the server back to Winsuite AD. On the laptop clients I restored the registry, put the program files back from the recycle bin and rolled it back.
My question to you is could you Dell image have contained and older version of the winsuite client? From past experience we never Ghost with the winsuite client installed on the machine.
Next time my plan is to Uninstall Winsuite AD Client from all the laptops using the setup.exe file with the -u switch. Once winsuite has been removed from every client. Upgrade the server to Winsuite EE and then run the winsuite setup.exe file on all the clients.
Hope this helps.
