Hi Experts,

We have an Exchange 2003 environment and we have firewall logs filling up with denies from some of the Exchange 2003 servers showing connection attempts to remote servers in the LAN on UDP 6004.

Over the last month or so, another team has introduced an Exchange 2010 servers, to allow them to move to Office 365.

There's no correlation between the destination IP of the connection and the Exchange 2010 servers either.

Any ideas why these servers have started to attempt to connect to other devices on 6004?
