Hi William, Check out TCPView http://www.sysinternals.com/ntw2k/source/tcpview.shtml It will tell you what app is using the TCP Port 80.

Any idea how I can find out what is using the port? Web Proxy service failed to bind its socket to 10.0.0.1 port 80. This could be caused by another service that is already using the same port or by a network interface card that is not functional. The error code specified in the Data area of the event properties indicates the cause of the failure. For more information about this event, see ISA Server Help. Nothing in IIS uses this 80 and the 10.x network is the external network ------------------------------------------------------ List Archives: http://www.webelists.com/cgi/lyris.pl?enter=isalist ISA Server Newsletter: http://www.isaserver.org/pages/newsletter.asp ISA Server FAQ: http://www.isaserver.org/pages/larticle.asp?type=FAQ ------------------------------------------------------ Exchange Server Resource Site: http://www.msexchange.org/ Windows Security Resource Site: http://www.windowsecurity.com/ Windows 2000/NT Fax Solutions: http://www.ntfaxfaq.com ------------------------------------------------------ You are currently subscribed to this ISAserver.org Discussion List as: tshinder@xxxxxxxxxxxxxxxxxx To unsubscribe send a blank email to $subst('Email.Unsub')
