Windows 10: DNS Suffix for Comcast Keeps Reappearing

Hi there, our VPN pushes two DNS suffixes when folks connect to the company network.


I've got a few users who have an additional DNS suffix of hsd1.dc.comcast.net


The issue is that additional suffix causes disconnect issues when on VPN.


I've tried several things including manually removing that suffix from IPV4 and IPV6, and disabling IPV6, but that suffix KEEPS COMING BACK!


Any idea how to keep that suffix from reappearing in the network settings?


Thanks

DNS Suffix Search List

Was poking around this AM to see if my DNS server selection could be improved or if it was ok. After Running Gibson's DNSBench.exe several times, convinced me I was already on the "best" one (openDNS).

When I did an IPconfig /all, I am looking at something that has puzzled me for a while and that is DNS Suffix Search List is listed as T-Mobile.com1?

OpenDNS is set on my computer, as well as in the Wan DNS1/2 on the router. I am using a Tmobile/ASUS TM-AC 1900 and T-Mobile.com1 is listed as the router Domain name?

Appreciate any clarity on this...Tx

windows10 dns resolution name problem - hostname.other not add the suffix dns

Hello Roberto,

Make sure that the Append primary and connection specific DNS suffixes
option is enabled in the Advanced TCP/IP Settings window of your network adapter. This option specifies that resolution for unqualified names that are used on your computer is limited to the domain suffixes of the primary suffix and all connection-specific
suffixes. For more information, you may refer to the following link:
Configure a Connection-Specific DNS Name. (Note: These steps are also applicable for Windows 10 machines.)

You might also be experiencing this issue because of DNS Devolution. This is applicable to computers that are in an Active Directory environment. For more information, you may refer to the following link:

DNS Devolution.
