I work in a small windows environment. We have a mixture of windows 2008r2 servers and windows 2003.
Recently, the primary fsmo role holder server died and was unrecoverable. I "seized" the roles from another GC with DNS running and rebuilt the failed server with the same name and restored most of the services. When I ran dcpromo, it ran, however, through a warning about being unable to join\find the domain, however, it did pull the DNS info from the other server.
The rebuilt file server seems to work reasonably ok, it is mainly a file and print server with DNS and dhcp. However, now, I cannot RDP to it and it it throwing RPC failures, failed replication and other errors in the event logs. To add to this, I cannot login from the console either, without rebooting.
Something going on between these two machines. Eventually, after a few days, both will unable to log in...
Tried running dcdiag and do get some errors. Running DFSR on both servers, to further confuse this, is that DFSR was having issues prior to the failure - files were rarely in sync - mainly because FRS and DFSR were running against the same folders - have since stopped replication on these "shares".
I think that there is some disconnect going on here and need a little help getting started troubleshooting this. Not sure where to begin, however, the not being able to log in concerns me.
