I've done around a dozen p2v type migrations using VMware's converter on servers with few problems. I usually use the stand alone converter from my desk. When I try to use it on this workstation PC it won't let me b/c of some Window's rights problem (workgroup remote install of a service won't work, thanks MS). So i install the converter on the box itself, and do a conversion.Twice now the conversion appears to work, but twice the VM hangs on boot up with a black screen and a non-moving cursor.
The only differences I can think besides what I've mentioned is that the PC itself doesn't have the sysprep files, etc. But it shouldn't need that if we aren't redoing the SID, etc. right?
