Event Type: Warning Event Source: Microsoft ISA Server Web Proxy Event Category: None Event ID: 14148 Date: 02/12/2005 Time: 11:19:23 AM User: N/A Computer: NOTAPIX Description: The Web Proxy filter failed to bind its socket to 192.168.1.253 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 guess I will follow these weak advice from Microsoft since this box only has ISA installed - no IIS. http://support.microsoft.com/default.aspx?scid=kb;en-us;275233 RESOLUTION To resolve this issue, quit any program (other than ISA Server) that may be using the port, and then reconfigure the program to use another port. Alternatively, run the program on another server and use Web publishing or server publishing to make the program available on the external interface.
