We have a server on our DMZ where users on a VPN can connect using RDP and then use the Nav client. we have opened the SQL ports through to our SQL server and all was running OK until 3 weeks ago. We have not made any chnages to our system at all but now users can still log into RDP OK and they can still use Nav ok for a while but then the connection drops (only SQL) and we get a message connection to server lost....
We have done a lot of work with the firewall and it is not blocking any SQL traffic.
We are running SQL Server 2005 64 Bit lastest service pack (4 I think) on a Windows Server 2003 64bit server. We are running Nav V5 sp1.
This is very frustrating and very differcult to determine what the issue is. I just hope that someone out there has had the same issue and can help [-o< .
