We are using Client SP1 for Windows 7 on a 64 bit machine:

Launch CMD

Then I type the following:

Copy F:\Siul\CLSINC\*. S:\Source\Siul\CLSINC\*.*

The above command causes Windows 7 to display the "Blue Screen of Death".

I have disabled caching as almost everything seems to cause a "Blue Screen of Death" when Caching is enabled.

F: maps to a Novell 6.5 Server
S: maps to a Windows 2008 Server.

Lucky for us XCOPY works without the GPF.
