Nearly a year ago our BDC crashed and burned. The server itself was replaced. I never did promote the new fileserver to a BDC and I've seen errors in the event viewer regarding FRS trying to replicate with the now non-existent BDC. I removed every trace of the old server from AD and DNS but apparently this isnt where FRS info is stored because I still saw errors trying to replicate with the old server.
Now I believe we're experiencing problems with AD because (I assume) FRS has reached a limitation in errors/attempts.
How might I go about removing the DC knowledge of the now non-existent BDC server so this issue doesnt repeat?
