Ok... solved this one... sorry for having overlooked something so simple
and asking so many questions!

For completeness of threads in this awesome forum, here's what the
problem was:

IIS was indeed set to only listen to the internal IP and "socketpooling"
was disabled indeed, BUT in IIS > web site > Properties IP Address >
Advanced > Multiple SSL identities it also listed "(All Unassigned)" !!!
Removing that entry and restarting both the w3svc and the ISA Web Proxy
serviced solved everything, of course.

Jim, you're the best!

Alfonso

Everything was working fine and now suddenly get the following error in
the Windows Event logs (Application Log):

Type: Warning
Source: Microsoft Web Proxy
Event ID: 14148
Description: Web Proxy Server failed to bind its socket to port 443.
This could be caused by another service that is already using the same
port or by a network interface card that is not functional.

IIS is in the same box, but it's set to listen only on the internal IP,
and  has SOCKETPOOLING disabled.  I've tested the network card and it
works fine thru port 443.

As a result of this, a Web Publishing Rule set to allow traffic to a
secure web site in IIS doesn't work anymore!  I can see the packets to
port 443 BLOCKED in the in the ISA IP logs.

WHAT OTHER SERVICE CAN BE TYING UP THE SSL PORT 443??? Could it be
another ISA service (firewall, scheduled download, or other) that causes
the problem?

Alfonso
