RPC Server unavailable over VPN

Hello,

I have a single domain spanning over multiple sites. One of these sites is accessed over a VPN between an ISA 2006 server and a TMG 2010 server.

In this particular remote site I have a domain contrroller runnig Windows server 2008 R2. Up untill a few hours ago its been replicating with no problems over the VPN, but now its not...

Whats changed is I have installed Arcserve 12.5 and have since uninstalled.

I can access the server by the UNC path from PC's within the same site, however I cannot access the UNC path from PC's in the remote sites over the VPN. I can however with a pc in this site connect to any other server over the VPN by using the UNC path so it is working over the firewalls and VPN.

I have run dcdiag and got this error:

DCDIAG:

Ldap search capabality attribute search failed on server SCSDC001, return
value = 81
Got error while checking if the DC is using FRS or DFSR. Error:
Win32 Error 81The VerifyReferences, FrsEvent and DfsrEvent tests might fail
because of this error.

And this in the event views:


The attempt to establish a replication link for the following writable directory partition failed.
 
Directory partition:

Intersite transport (if any):
CN=IP,CN=Inter-Site Transports,CN=Sites,CN=Configuration,
 
This directory service will be unable to replicate with the source directory service until this problem is corrected.
 
User Action
Verify if the source directory service is accessible or network connectivity is available.
 
Additional Data
Error value:
1722 The RPC server is unavailable.



I ran replmon too and in can;t connect to any domain controllers on the otehr side of the VPN.

To complicate it more, i have virtual servers running on this DC and they can connect by UNC path to servers accross the VPN.

Any help much appreciated!!

Thanks

Check whether the FRS Service is running on the Remote Site's Domain Controller on which you had installed & uninstalled ArcServe.
