When doing an Undo (roll back) of a migration job the following error is received in the job log
"failed 10/27/2009 11:29:42 AM Error 0xea0000aa. Error during bulk object restoration"
"Error 0xe1100012. Cannot initialize Migration Agent on host servername"
"Error 0x800700d8. The image file #1 is valid, but is for a machine type other than the current machine."
There is a problem with the DC being used by the DSA when performing the Undo.
Please change the preferred DC/GC in the DSA Agent Manager dialog to another server.
