Problems after unsuccessful DC demotion

I've been reading technet and KB articles for about a month. After some problems in my domain, I had to demote the new server I had been working to add to the domain. I wasn't able to do it with dcpromo, so i had to use adsiedit. I followed the knowledge base article for demoting an orphaned DC. I then reinstalled server 2008 on the new server. Unfortunately, there are still lingering issues. Currently there is only one DC on the network, gets call it PG. PG isn't looking for replication partners, so i figured everything was okay. It seems the other server was successfully removed. However when i tried to edit some group policies, i realized i was getting the "RPC server unavailable" error. The server failed to replicate with its partner for a while and I think that's what started all of this. I remember something about a journal wrap error (ive read so many articles, they're blurring together).

I followed the knowledge base article for that issue and ended up doing a non-authoritative restore. No luck, RPC server still unavailable. Then a few days later, AD failed all together. I restored with a system state backup I had made. I was in a rush to get the server going again, and i forgot to save a dcdiag log of the issue. I remember the group policy service throwing error 1058. After the restore, AD works again and users can access network shares, but I still have the "RPC server not available" issue. Should i have done the authoritative restore as well? 

I have an old system state backup I'm thinking of using, from before I added the new server to the domain. Would it be a good idea to restore with this? I might loose my user account.. Which isn't a huge deal, but I'd rather not. I'm not sure if anything else has changed since.. I can't afford to loose anything other than my account. I guess I could just go back to a current system state if something happened though.

Excuse the wall of text. Any help would be appreciated. I'll post my current dcdiag output in my next post.
