As part of trying to troubleshoot some poor Internet performance, my ISP is asking me to "update your DHCP with the following DNS entries; the ones you have work but are older servers..."
The problem is, I'm quite sure I've never put any DNS entries in the SBS 2008 server. I've looked through DNS and DHCP and cannot find any DNS entries pointing to our ISP's DNS servers.
In the DNS entries for the server's (single) NIC, the single DNS entry is its own IP address (192.168.1.x)
Before we went with this ISP, we had simply programmed the ISP's DNS IP addresses into the router itself. Is there somewhere else in the server I should be putting these entries? The only thing I remember about this from the server migration a year ago was the migration asing me the IP address of my router.
If the ISP is asking me to update my DNS IP addresses of my ISP, isn't this the router they're talking about? Can someone shed some light on this?
