We have a program that communicates to a webservice from a remote site. This program works great at several locations. However at one location there is a problem. At this location, The remote sites use cisco 1760 routers. The main site uses a Cisco 3745. These are connected using frame relay, and IPSEC tunnelling.
After a few days, one or more of the remote sites will quit talking to the web server. You cannot tracert or ping, or see the webserver at the main site. You can however tracert or ping to any other machine at the main site - it's just that particular route that doesn't work. You can also get to the webserver from other machines.
The windows firewall is not running. The remote site is running Symantic antivirus, but they swear there is no firewall enabled.
Shutting our service off, and then starting it back up drops the connection, and then all traffic starts working again.
To me it sounded like some sort of intrusion detection, but they swear it is not on. Any Ideas?
