Unable to reseed a database from one site to another - Exchange 2010

Hi all, please have a look at the message below and advice. I havent been able to find something useful else where. Please note that I have tried reseeding the database multiple times already, but no luck. Also, I had DB03 and DB04 seed and replicating fine for 2 months now. We were to monitor before moving onto DB02 and DB01. So the replication for DB03 and DB04 is working fine across the 2 sites. The only change that happened is that I installed Kaspersky for Windows servers a month ago (with all the possible exclusions) but I even disabled Kaspersky and retried, but no luck. Everything is pinging everything else. Thanks to all.

The Microsoft Exchange Replication service was unable to perform an incremental reseed of database copy 'DB02\server-in-site-B' due to a network error. The database copy status will be set to Disconnected. Error A timeout occurred while communicating with server 'server-in-site-A'. Error: "A connection could not be completed within 5 seconds."
