Here is my situation:
We have a SBS2000 acting as gateway, and a web server inside the network. Up to this morning all was well: the web server was published through ISA using http headers, and the SBS IIS itself was also serving some pages.
This morning I had to change the physical link to the internet and since, I'm unable to publish my sites, from either server.
Of course the change included a change in our public IP.
The rest is OK: we surf, we get our mail through exchange relay, we do FTP, so it must be somehow that ISA is off the track but I can't find the trick.
If you want to see the http answer, go here: http://www.floredefrance.com/
its one of the websites.
Thanks for your help !!!!
280 points is all I have at the moment, sorry guys !
