We have (2)DC’s, each in their own site. Everything was fine until we renamed the admin account. Then we started getting errors every 5 minutes with name/SID mapping errors. Q247482 on technet explains the issue….however, after going into the gpo’s for local, DC, and domain, there are no instances of administrator assigned to user rights,yet the effective rights under local gp still shows administrator for “log on as a service” and “act as part of the OS”. This is only happening on 1 of the 2servers. If I remove the (renamed) admin account under the DC gp, then re add it, it fixes the problem for a few 5 minute intervals, but then it comes back. I can’t find administrator anywhere, in any GP, yet it keeps reappearing as an effective right for just those 2 user rights. Any help/ideas would be appreciated…..
