No ip mac 10 5 dns not updating
The DNS Servers list may be empty, it may have one or more entries that are grayed out, or it may have entries in normal dark text.
Grayed out text implies the IP addresses for the DNS server(s) were assigned by another device on your network, usually your network router.

I have not applied any combo updates since it was purchased etc.
If the DNS list is empty, or has one or more grayed entries, you can add one or more new DNS addresses to the list.
Any entries you add will replace any grayed out entries.
Note: Routers can be configured to allow some services to use the Internet (such as Mail) while preventing other services from using the Internet (such as web browsers).
If you are not sure how your network is configured, contact your network administrator.
