I recently did a swing migration and we are now up and running on a premium windows 2003 Small Business Server. The server is the Domain Controller, exchange server, DHCP and DNS server.
So everything was workig just fine and I went to install the ISA firewall which comes with the premium SBS 2003. The installation went through a wizard where I set everyting up as per our network setup and then restarted.
Uppon the restart, every client on our network had no access to anything. The clients could not access the internet, the server, exchange server, etc... However I could ping the server from each client.
I called another tech in and he coulnt figure out the probelm either. After a day of being confused I finally uninstalled the ISA firewall and everything went back to normal.
What is going on? why is ISA blocking clients? I really need to have a firewall on this server, its just out there right now waiting to be owned.
