I tried just repairing an MDT6 install (it's running on a network serial number), but it didn't fix it. I'm tempted to try the Reinstall option using Add/Remove > Change > Reinstall, but I really don't want to if it will trigger a reauthorization process. Our licenses and allocations are kind of screwed up right now and I don't want to add grief to our IT guys (located two states away).
