thanks greg for the input but the ISA in question is just used as a proxy
server on a dial-up connection and thats its primary function not as a
firewall. steve jumped to conclusions. it seems that the clients aren't
seeing the proxy server at all. if i log in as the Administrator on any
terminal i can go online with no problem-but when i log in as a user the
browser does the following: in the status bar i see it looking for
www.msn.com then in returns the IP address of the site-it then sits at
this-after a long time out period i get a DNS error on the page. i know its
not a DNS error-the DNS is passing simple and recursive testing and the
Administrator user has no DNS problems. all DNS settings are correct-i'm
confident of that. my feeling is that when the user installed the firewall
client it must've made entries in the registry that didn't get removed on
the uninstall. have you any ideas on what these could be? its bugging me at
this stage.....
thanks
troy

I think the point was more that it shouldn't be done on the firewall. In
most cases you should be able to scrounge enough money together for a
Pentium and install some sort of firewall, even if it is Linux. Then put all
the goodies (SBS, ISA, EX) etc behind it not on it.
More to the point i spose, where is the web traffic breaking down? How far
do you get, is it a DNS error or is it ip related. Did you restart the
server at all, what does the error message say as well as the firewall logs.

I didn't ask for a debate on the what should or shoudl not be done?
But its the small business server server-so you're telling me then when i
install the server i cant install exchange because i'm installing the ISA
option-hmmmm? funny one that really when it all comes bundled together as it
does? anyways i didn't really ask to be ridiculed. SBS is designed for this
sort of setup-this company doesn't have the budget to put 2 servers in-then
they couldn't run SBS anyway. they have 10 users-and some of them have to
have install rights as thats just the way it goes in 2 office companys.
can someone just answer the question if they have any ideas-i haven't seen
this problem before.
thanks

You are kidding, Terminal Server on a firewall????....lol...heard everything
now. Not even locked down so clients can install their own
software....rotflol
Uninstall ISA, get separate hardware and reinstall it. NOTHING should be
installed on a firewall.

hi everyone
just popped over from exchange list with a wee ISA query. i have a company
that use ISA server sitting on windows 2000 terminal services. only the
administrator can go online from a a terminal. everything was working fine
up until a week ago then all stopped-i did notice that one of the users had
installed the firewall client on his terminal session-i remember reading
somewhere that this is never to be done. what i get now is when a user tries
to access a web page he/she gets finding www.website.com then the IP address
and then nothing-and the error returned is not an ISA server error. i'm not
new to this but his has me stumped. i've all the usual settings correct-but
i'm obviously missing something-i uninstalled the firewall client incase it
was that but still no joy-id appreciate anyone shedding some light.....
