Thanks for the reply. Glad to hear a reply as this is my second posting.
The published website with window integrated authentication is accessible to any users who is connected directly to the Internet eg. via cable or dial up.
But users acessing my website from another network behind their own Checkpoint or ISA firewall are not able to get it. They are using Win98 and IE6.
I have tried changing the authentication methods to include basic authentication. The login dialog prompts three times and then failed to access the website. The dialog shows firewall as the client's firewall host name.
A MS support mentions that basic authentication uses port HTTP but NTLM requires additional ports and protocols to be released on the client's firewall. But he does not specifically mention which ports are those.
Based on the above, is there some ports and protocols that the client's site need to open up?
Appreciate your reply soon as the engineer who is managing the client's firewall will be onsite to do some maintenance work.
Pardon my impatience request as I have been stuck for a while and the other parties are insisting that it is my firewall problem.
Yours sincerely and gratefully,
