Hi Guys, we have a domain and two sites, one head office and a branch in different City. Head office has two DC as DC1 and DC2 on Windows 2008 R2 and also a DC3 in branch Windows 2008 R2. now the issue is there is no replication between branch and head office, once dig into the issue found KCC events. the scenario as follows.
VPN link is ok between the sites.
DCs can ping each other with IP and Names.
net view \\DC1 and net view \\DC2 is fine as vise versa
But net view \\DC1 or \\DC2 from Brach office DC3 is showing errors. its like cant access shared folders from Branch office and also from Head office DC to branch.
The attempt to establish a replication link for the following writable directory partition failed.Directory partition:
DC=Domain,DC=com
Source directory service:
CN=NTDS Settings,CN=DC1,CN=Servers,CN=Headoffice,CN=Sites,CN=Configuration,DC=Domain,DC=com
Source directory service address:
k826e336-99a7-4g2d-bdab-113db2a0f5f6._msdcs.domain.com
Intersite transport (if any):
CN=IP,CN=Inter-Site Transports,CN=Sites,CN=Configuration,DC=Domain,DC=com
This directory service will be unable to replicate with the source directory service until this problem is corrected.
