Hi there,<o:p></o:p>
I am glade to post my first topic here. I faced to a very deep and serious problem All day. Actually My DNS integrated DC server is down with event ID: 4000 & 4007. For your information My DC was the only server in our site and as the connection of our sites to the other sites and DCs has been disconnected because of VPN matters, our server didn't has any replication with the rest of DCs; In addition we have done lots of changes in our OU.<o:p></o:p>
I suppose this problem has occurred when our VPN tunnel linked up with packet loss this morning. All in all what if I go through new dc installation, I'll lose all my changes during the disconnection. <o:p></o:p>
In this case I followed many solutions but it does not work. the problem is my DNS server is down and as I didn't have any backup so my network is complete mess. <o:p></o:p>
Any help would be appreciated.
Best Regards,
Pooyan
