Let me start by apologising for my bad explanation, I know nothing about ASP :(

This is the scenario:

I have a Windows 2K3 SBS, 10 XP workstations, behind a router/modem/firewall.

There is an https website that my users need to connect to, login and then submit information via a template in asp.

They can connect to the https website and all other https sites. Port 443 on the firewall is open. But on this particular website, they can login in and authenticate without problem. After this stage, there is a facility for the user to fill out a template with data and submit it in asp.

The PROBLEM is they get a page can not be displayed :(. I have used IE and Firefox, but to no avail. The problem is on the server and all work stations.

I can connect to and send data via this asp template on all other computer away from their network!!

They can submit asp data on other websites with no problems.

Please can anyone give me some pointers to over come this major issue?

The company that we have the problem with has upgrade their servers, firewall, hosts and the problem started the day after this. They maintain it is an internal issue.

Please can some kind sole help me out? An envelope of money awaits :)

Sounds like a DNS update problem. Have your server and workstations been rebooted since the changes were made to the website?

Life is more painless for those who are brainless.
