I try to keep up on new or updated MS KB articles and often check to see how
they correlate with my environment. I noticed that 875495, dealing with USN
rollbacks, was updated earlier this month. As I've experienced two AD
issues, both of which needed PSS involvement (one dealing with sysvol
inconsistency and the other which wound up being the RID master going on
temporary strike) I figured that I'd do a quick check as described in the
article. On the good side, the USN's are consistent between controllers.
On the disconcerting side, I got a little more information than I was
expecting. Besides my DC's, I also got USN listings for several GUIDs. I
assume these are leftovers from DC demotions and only remain in the form of
historical data. Do I need to worry about these (especially the DC1
(retired) listing) and is there a way I can resolve the GUIDs to names, find
where this info is hiding, and clear them out?
Thanks,
Scott Klassen
