Hi Folks, Thanks to Axton, I believe we have identified the problem. When he suggested a "traceroute" between the Mid-tier server and the AR Server, I discovered that ICMP traffic was not being routed. That got me thinking that there might be some other "issues" with the firewall that had been imposed on me. After describing the symptoms to the firewall guy, he instantly knew what the problem was and corrected it in seconds. Apparently, their default behavior is to setup a one hour timeout on TCP traffic unless there is a Linux machine involved. He suggested that the person who setup the rules for this particular configuration did not realize that the Mid-tier servers were running on Linux. He adjusted the timeout and I am now waiting for an hour to elapse so I can see what happens. But confidence is high.
Thanks to all who replied with suggestions. This job would be a lot harder and more frustrating without all of you who are willing to share your knowledge and your time. I appreciate you.
