I have the following question for this scenario.
*I have around 60 AD sites worldwide and I have deployed one more site in a company that was recently acquired by my employeer. We need this domain controller on the new site while we integrate this acquired company to our Software and Domain infrastructure.
*The acquired site is configure to connect to acquiring company headquarters only and there is a firewall in between the two sites. *Firewall has been configured to allow any to any communications between the new DC and all existing domain controller.
*New AD Site has been configured to replicate with headquarters site
* The new site can communicate with 99% of domain controllers except for the DC in a European site that contains conflicting IP ranges therefore communication has been blocked by the network team.
*Repadmin /syncall works with no errors. However repadmin /replsummary returns error 58 in regards to that European site.
Based on above data my question is: Is it okay to run the domain controller with this limitation for a couple of months while the IP conflict situation is solved and all AD in all sites can openly communicate with the new DC? What issues could I be facing if I operate the DC in this conditions?
