Multiple Domain Controllers and one failed

Hi, I have three sites connected via Sonicwall VPN.  Site A hosts 3 Domain Controllers (1 x 2008 and 2 x 2003).  Site B and Site C, each have their own Domain Controller (each on 2003).  All sites replicate to the same domain and forest.  Recently, one of the original domain controllers in Site A went down and would not come back up.  So I officially seized the FSMO roles onto one of the other domain controllers in Site A and removed the dead domain controller from the domain.  All Site A and B domain controllers are working fine.

However, Site C domain controller will no longer replicate.  I checked Sites and Services/NTDS settings and confirmed that Site C was automatically replicating to the dead domain controller. When trying to manually replicate I get the below error.  I also went into properties and can change to an active domain controller in site a but still get the same error.  Unfortunately, this is has been an issue for over 30 days now.

Is there another way to reconnect this domain controller to the site a domain controllers?
