Hey,
I've been trying for a day to replicate a 2k8 AD DC server to a new 2012.
So far without success I'm afraid.
I keep getting a "ADPrep execution failed --> system.componentmodel.win32exception (0x80004005): A device attached to the system is not functioning".
I checked out Adprep's logs and found this:
Adprep was unable to complete because the call back function failed.
[Status/Consequence]
Error message: Unable to access the computer "blabla.blablabla.com". Access is denied.
(0x80070005).
I used the Administrator user for authorization.
Drawing blanks here, can anyone help?
