You can also try running the following command from the command prompt to determine which process is using port 8080. netstat -ano | find /i ":8080" Cross reference the PID (furthest right column) against list of processes in Task Manager or you can use the following command at the same command prompt: tasklist /FI "PID eq <enter PID from above command>" (e.g., tasklist /FI "PID eq 204") Cordially yours, Jerry G.

Recently, I have not noticed my ISA server alert the warning message: Event ID 14148, source Microsoft ISA server Web Proxy, Description: The Web Proxy filter failed to bind its socket to 192.168.5.1 port 8080. This may have been caused by another service that is already using the same port or by a network adapter that is not functional. To resolve this issue, restart the Microsoft Firewall service. The error code specified in the data area of the event properties indicates the cause of the failure. I've found the related information on http://forums.isaserver.org/m_2002020318/mpage_1/tm.htm#2002022651, but my server does not run IIS service Any help would be appreciated.
