Domain controller was setup, then taken offline for longer than the tombstone limit. Now I can't get it to replicate again with DC2. please, any solution to replicate back
If a domain controller has tombstoned then the solution is to seize roles (if necessary) to a healthy one.
then perform cleanup to remove remnants
then rebuild the failed one. I'd use dcdiag / repadmin tools to verify health
correcting all errors found before starting
any operations. Then stand up the new one, patch it fully, license it, join existing domain, add active directory domain services, promote it also making it a GC (recommended), transfer FSMO roles over (optional), transfer pdc emulator role (optional), use dcdiag / repadmin tools to again verify health.

Thank you for your question.
If the tombstone limit already passed then it may not Sync with AD properly and its better to decommission and promote new one with new name and ip or you have to use meta cleanup for AD objects.
Please also consider to download Active Directory Replication Status Tool and see how How is the health of AD now.
