Hi Darryl,
You'll have to create access rules on the ISA firewall to access the
protocols and sites you require.
Also, make sure the system policy matches your organization's
requirements.
HTH,

Hi, I have an Exchange 2003 server behind an ISA 2004 server
Outbound mail is not working. I have not deployed a SMTP relay at this
point...
I can resolve external DNS sites from the DNS forwarder on
ISA..... Any suggestions?
Also, ISA 2000 allowed internal servers be accessed by RDP and
the Internal web servers via the DNS names... that functionality has
stopped. I am only able to access internal web servers via NetBIOS
names. External publishing of web and RDP works just fine
Thanks
Darryl Janetzki
