See the link to "EventID 14141 from source Microsoft Web Proxy" for information on this event.
If the server has IBM ServerRAID manager version 8 with the "ServeRAID FlashCopy Agent" installed, it will prevent ISA2004 from binding to port 8080 since the agent has already done so. On my system, I changed the service from automatic to manual as a workaround.
A very simple way to check if IIS socket pooling is still active, is to check the output of "netstat -na" for an entry like "0.0.0.0:80". If this is present, then IIS will try to bind to all available IP addresses on port 80.
This problem occurs when the Web Proxy cannot bind the forward Web listenerís port because IIS is already using the port. See ME284662
for more information about this issue.
This can also occur if the internal NIC is disabled (for example, if the internal NIC is attached to a switch and the switch is rebooted or for a short time in a downed state), and then re-enabled. The Web Proxy service sometimes fails to bind (Firewall and secure NAT still works). Stop the Firewall Service then restart it. Web Proxy Service will then re-bind.

By default, IIS looks at port 80 on all IPs on your server. You can configure IIS to only listen to a unique IP, but the IIS service itself still listens to all IPs. To use ISA and IIS on the same box you'll need to disable IIS connection pooling (see ME238131
ISA could not take control of port 80 (http port) on the local host. This is most probably due to another website on the server or another program running which uses port 80. To see if a program is using port 80 go to run and type in http://127.0.0.1:80/ to and see if a page is visable. If so stop the service from using port 80, or move it to another port. If there is no webpage visable, type in netstat -an at the command prompt and see if Port 80 is being used.
This issue can occur if the Web Proxy service is unable to register itself to listen on the port that is specified. The Web Proxy service cannot listen on the port if the port is being used by another program, usually Internet Information Services (IIS) or another Web server. See ME275233
