Dear Users, I have a strange situation. I have bought a new HP DL380 server, installed with Windows 2003 Server Standard R2, installed Exchange 2003, promoted to domain controller. Added client, configured and everything works well.
I install ISA 2006 Standard and create an accesso rule for interneal to external, (all protocols), localhost to external and a publishing rule for SMTP (in exchange I bind the SMTP server only to the internal IP). Also a internal to localhost (all protocols)
Everything works well, client, outlook etc. I browse the internet from the server and everything works well.
The strange thing is when I try to browser from the client. Nothing happened I get a DNS error (in 0.5 sec). But I can ping from the client to outside and I can make a trace and works well. When browsing with HTTPS everything works well!
Another strange stuff, when try to connect from external with telnet on the 25, I get the exchange header answering but in 1 sec the connection close. (you can try mail.swissoncology.com).
On the server the IIS6 was moved to another port. And also disabled.
Any ideas? I tryed also to reinstall but the problems still... Thank you very much Regards Nick

Nick, Try disabling the Web Proxy filter for the HTTP traffic rule. You can find it... - Open the rule properties - Select the Protocols tab - Select HTTP and click on Edit. - Under 'Properties' tab, you should see the 'Web Proxy' checkmark.
Also, you can try disabling the 'HTTP Filter' under Configuration -> Add-ins
