Hello all.
We currentely have a problem with our Exchange 2013 server.
As first i'll explain the situation.
2 servers, both with Server 2012.
Server1: AD, DHCP, DNS, Exchange, RAS.
Server2: Filesharing, TS, SQL for our programs.
Both servers are running on Hyper-V.
The problem is simply, Exchange is running fine after a startup.
After a few hours receiving and sending emails it just stops.
When i disable the VPN everthing works fine, after enabling the VPN it will stop after a few hours.
There are some articles about the same problem, but haven't found any who has "solved" the problem after disabling the VPN.
With telnet we get the error: 451 4.7.0 Temporary server error. Please try again later. PRX5
We found the following log rules:
