we got a serveral server in our local network. but sometime the 4506 and 6503 could not communication well.I mean it was very slow about service each other.
and then we always take a backup from server farm passing by 4506.
But when the server started to get backup DB, suddelny the traffic was increased and we could not service. so we just stopped to take a backup DB from server.
I attached our 4506 and 6503 'tech-support'file and diagram.
Please, check our configuration and what should I do next...
