Cleanup your mess!

Random connectivity issues... Man can DNS can be a pain, shouldn't it be the first thing you check? takes 5 to 10 mins, looking for some stale gc, ns, or invalid DC locater records. Think that might cause some interesting authentication problems? Mmmm, I think so... and it all boiled down to a failed SBS migration that nobody mentioned till it I started asking did blah blah...

Not to mention a corrupted gpo and the security permissions associated with it.
