Our client is using SBS2011 (A swing migration from SBS2003)
We are troubleshooting some DNS issues and when we run DCDiag /test:dns we get some erros.
Looking at their Network card settings I can see that their Preferred DNS server is the IP address of the server, but they have an Alternate DNS server IP address set to a DNS server of their Broadband Provider.
I am sure this is not correct.
Can anyone help / advise please.
