none
Primary DC Not Coming back up and syncing

    Question

  • I have a problem. We have two DC's at one site. DC1 (dbserver) and DC1(DC10). DC2 is operating fine and is 2k8R2 server, DC1 is SBS 2011 and is not doing so well. I tried restores from three different backups and none are working properly. DC1 exchange, ad, dns, are not working properly. I thought this started as a DNS issue, now it seems to be a AD issue. Here is the dcdiag:

       Trying to find home server...
