you getting error "the rpc server unavailable" relates port being blocked or network connectivity issue or due dns misconfig.i suggest contact network/security team verify whether related ad ports being configured , allowed on firewall communication. portquery free tool ms can downloaded , installed verify necessary ports opened or not.

also, disable local windows firewall service, default enabled in vista/windows 2008 , above. check network connectivity , latency.
disable windows firewall:http://technet.microsoft.com/en-us/library/cc766337(ws.10).aspx

it can caused antivirus software with many of them sporting new feature called "network traffic protection," can efffectively block necessary ad traffic

active directory , active directory domain services port requirements

troubleshooting “rpc server unavailable” error, reported in failing ad replication scenario.
http://blogs.technet.com/b/abizerh/archive/2009/06/11/troubleshooting-rpc-server-is-unavailable-error-reported-in-failing-ad-replication-scenario.aspx

ensure following dns setting on dc:
1. each dc / dns server points private ip address primary dns server , other remote/local dns servers secondary in tcp/ip properties.
2. each dc has 1 ip address , single network adapter enabled.
3. contact isp , valid dns ips them , add in forwarders, not set public dns server in tcp/ip setting of dc.
4. once done, run "ipconfig /flushdns & ipconfig /registerdns", restart dns , netlogon service each dc.
not put private dns ip addresses in forwarder list.
5.assigning static ip address dc if ip address assigned dhcp server dc.it not recommended.

hope helps

best regards,
