Sure, I can help with that problem.. Just copy the profile which you are successfully and apply that to default.. I do that all the time..
Google this line: windows 7 profile copy.. Open the doc irongeek.com.. Follow the instruction on copying default profile..If you need more help let me know.. (can't copy links today)
I went through pain during my deployment..
How many VM's are you running.?
Also please give me points for any help I have given..
thanks,
suri
