I agree with Bakunin that you leave us all guessing which isn't good for proper diagnosis.

However, given the scenario you describe, I'm going to guess what the problem is. Absolutely, no guarantees though.

The thing that's changed is your internet connection and the router. Everything worked at the previous site.

It's quite possible that your server is configured to be the gateway (and proxy) for internet access and is configured to be a DHCP server.

Almost all new routers are configured to provide the DHCP service by default but you can only have one DHCP server for a site.

So probably your new router is a DHCP server, is providing the workstations with ip address leasing and gateway/dns information, and so the workstations can access the internet. The server has the old gateway ip address still hard configured but that's not there anymore so it can't access the internet.

If I'm correct you need to stop the new router being a DHCP server and then reboot all your workstations. Also, configure the new router's ip address into the server. Also, check the DNS service is configured properly for the new internet connection/provider.

I repeat, I am just completely guessing here. Hope that helps.
