I would want to achieve this setup if possible:
A Windows Server 2003, Standard Edition with:
Active Directory – Installed
DNS Server – Installed
ISA Server 2006 – Installed but with error
Exchange Server 2003 – Not yet Installed
All of these should exist on one machine.
However, my problem started when I installed the ISA Server. The server installed just fine but when I clicked on the Firewall Policy under the Array in the navigation pane of ISA Server Management, it flags an error on top that says (in bold RED) : Unable to retrieve data from (server name here). How do I fix this?
