ISA and Domains

Locked

Problem:
OS on Server: Window 2000 SBE with Exchange Server 2000 and ISA Server 2000 setup.

LocalDomain: .com
Email addresses: @.com
Web Site Hosted by a 3rd Party: www..com

Because of the setup as describrd above, ISA Firewall pops up a Firewall Logon Dialog Box but still refuses to allow access to the hosted web address.

Things tried so far:
1. Add ISA Server IP Address as Gateway, it worked initially but has since stopped due to change over to DSL.
2. Auto-download the website to the cache via ISA Server, seemed to work but not anymore.

Any ideas would be greatly appreciated.

3. Added the hosted website to the DNS Server, didn’t work.

A lot of answers depend on how you have configured ISA server as it’s highly configurable. If you have just default settings try these solutions.

Install the firewall client onto workstations [location is ///clientapps5 ]. Backoffice internet access group is the default security group assigned by ISA server for internet access. Make sure users who are allowed internet access are part of this group [use AD to add users to this security group]. If users try to access the internet who are not part of this group a popup window will ask for logon credentials.

ISA server and IIS will conflict with each other if they both use port 80. Since ISA server acts as a proxy server all clients have to be configured to use the proxy server with a port other than 80 to access the internet [try port 8080]. Assigning the proxy server depends upon where ISA is installed e.g. stand alone box or on same box as W2K and E2K.

note ISA server works best with W2K SBE using two NICs. Run the Connections management program from the W2K SBE Administration Console to configure ISA server with two NIC and a router [if you are using a router between ISA and Internet.

The problem I have is that the public domain and the private domain are the same and due to this, I cannot browse the website. The Firewall throws up the Logon Dialog Box. I need a way around it. The ISA allows access to every other website.
