I just updated the drivers to our NICs (our server has 2 NICs) and now workstations cannot connect tot the internet or get email. We have our broadband line come in into the bldg, it connects to a router, our server is connected to this routr via NIC 1. NIC 2 connects to the patch panel so the wkstations can connect to the server and the internet. Both Nics are set to static IP addresses.
NIC 2 has the internal IP address set up with the a private IP address, NIC 1 has the public IP address provided by our ISP.
On the server, I can connect to internet, ping the switches, ping the wkstations and ping a DNS address.
On a wkstation I can ping the server, ping the swithces and ping a DNS address but I cannot see web pages on the internet with the internet browsers or get email either. DNS service is running on the server, so Is WINS service and dhcp service (WINS is set up on NIC 2). We have ISA servre 2004. the firewall service is running and so is the remote routing service. All exchange related services are running also. I ran the diagnostic hardware test on the NICs and they checked out to be OK.
I am at a loss
