When I change my DNS it will not let me Remote to server or Receive email what do I do?

basically it just means the last change to DNS was not correct or not well configured.

however, please first try accessing the same remote host using IP address to double check if there is any routing or firewall issue blocking your access as well.

If there is no problem for accessing by IP address, it definitely suggests a DNS issue. in this case, please advise why and how you made the change.

I can access the server from our other domain and from the Ip address. We have 2 domains on our server for email reasons.

So instead of mail.xxxxx.com I can access it from mail.yyyyy.com when using remote desktop. We made the change because we had a company do our website. I made the change only on register.com. In which only consisted of me pointing to a new name server.

> So instead of mail.xxxxx.com I can access it from mail.yyyyy.com when using remote desktop.

this can confirm DNS got an issue.

you pointing to a name server? you mean you made changes to your domain's root DNS server from your DC or your ISP to something else?

From our root DNS server to a new name server.
