Hi I have an application, App1, running on a Windows 2003 SP2 Server, Server1. App1 connects to a third party vendor server on the Internet, Vendor1. App1 is configured to connect to the internet via one of our proxy servers, Proxy1 on port 3000. For some reason, we are getting errors on the application. I checked the logs of the app, and it appears that the connection to Vendor1 keeps dropping and then reconnecting a few minutes later. Sometimes the drop lasts more than 5 minutes, hence the errors. I've checked the Application and System logs on Server1, they don't show much. Any ideas on how to troubleshoot this? I was thinking Wireshark or something but not entirely sure what I should be looking for?

Sounds like an application related issue. Did you check with your application vendor? Do you have any log files from this application? During the “disconnect” make sure App1 server can access internet.

I don't know you, but in my life experience I found out that a lot of web applications do not work well when a proxy server is used. Check with your vendor1 if the applications you bought is proxy compatible.

Any update on the issue?Santhosh Sivarajan | MCTS, MCSE (W2K3/W2K/NT4), MCSA (W2K3/W2K/MSG), CCNA, Network+ Houston, TX http://blogs.sivarajan.com/ http://publications.sivarajan.com/ This posting is provided "AS IS" with no warranties, and confers no rights.
