Either uninstall ISA from that server, or uninstall Apache from that
server.

Both need to use port 80.

Read the ISA help, browse www.isaserver.org.

Subject: [isalist] how to access existing applications on the ISA server
itself

http://www.ISAserver.org

We installed ISA Server 2004 on a Windows 2003 server, for the 2
following purposes, only :
a) control user Web access by using  the integrated Windows
authentication mode (NTLM) which allows transparent user authentication
(users are not prompted for user/password when surfing the Web) b)serve
as a caching machine ; this machine has only 1 Ethernet card;

Apart from ISA server 2004, there is an existing Web Apache server
located on this same Windows 2003 server, which should be accessible for
all internal users ;

Once we installed ISA Server 2004, this Apache server became
inaccessible from the internal users, even after creating a specific
access rule allowing access from  Internal network toward Local Host for
all users on the right Apache TCP port (actually, this Apache server was
only acccessible locally, from the server machine itself);

Even, after stopping totally the 3 Windows services installed by ISA,
this Apache server was still inaccessible ; (If we uninstall ISA, this
Apache server becomes accessible again)

We did some tests by modifying some ISA parameters and the results are
as follows :
1) if we uncheck the option "Authentication required for all users"
under Network ==> Internal network ==> Properties ==> Proxy Web ==>
Authentication, then, the Apache server became accessible; unfortunatly,
with this unchecked option, the Web access (based on Access rules, where
users are specified) became impossible ;
2) if we check this option (to force user Authentication, in all cases),
Web access rules work OK, but access to Apache server becomes
impossible, as before

Question :
1) How can we solve this problem ? 
any help is welcomed
