Is it a virtual system? What version OS? Have you verified the time sync is working properly? Any virtual system should point towards a hardware service. Finally when I see the word "recently" I have to ask what has changed when this recent time event started? Have you verified if any patches were installed that affect how LDAP operates.

Recently I started seeing replication errors between the two sites, intrasite replication is working properly. I found that if I reboot all the DCs, things seem to clear up for a while, then replication breaks again. I've verified all the DCs are pointing at themselves for DNS, all services seem to be running fine. We have all firewall ports open between the two sites for both TCP and UDP and we have disabled WAN acceleration. If I manually force a replication, I get different errors based on the direction I force it:] repadmin /replicate mtiden3a01 mtistl3a01 dc=ext,dc=mitekinc,d c=com Repadmin can't connect to a "home server", because of the following error. Try specifying a different home server with /homeserver:[dns name] Error: An LDAP lookup operation failed with the following error: LDAP Error 81(0x51): Server Down Server Win32 Error 0(0x0): Extended Information: repadmin /replicate mtistl3a01 mtiden3a01 dc=ext,dc=mitekinc,d c=com DsReplicaSync() failed with status 1818 (0x71a): The remote procedure call was cancelled. Anyone seen anything like this before, and any ideas why reboots fix it for perhaps a few days then it breaks again? Thanks.
