I am changing the configuration on an SBS2008 server, long story short, there were 2 x internet connections running on the same LAN. One gateway was 192.168.2.254 (no longer active), the other is 192.168.2.253 (Telstra cable, still active). All was working O.K until we disconnected the .254 gateway. At this time I changed the gateway on the LAN adapter on the server to 192.168.2.253, left the current static IP as it was 192.168.2.20, and left the DNS entry on the LAN adapter as it was 192.168.2.20 (the server is running DNS so should use itself as the primary DNS).
I added 2 x forwarders to the DNS properties (DNS servers from the ISP). But the DNS server is unable to resolve them.
I can get to the gateway through IE (192.168.2.253), but can't ping any IP or address outside the LAN.
The server won't connect to the internet, but other PC's on the network can access the server (file sharing).
What am I missing? I can supply screen shots if there is anything particular you want to see to help in the diagnosis.
Your help appreciated in advance.
