If a query using the primary suffix fails, and the Append Parent Suffixes option is checked, the resolver strips the leftmost element from the primary suffix and tries again. The TCP/IP settings for each network interface can have a unique DNS suffix, populated either statically or with DHCP.The user interface calls this the Connection-specific Suffix.Yet, as you’ll see in this article, most of these issues don’t require extensive diagnostic work or sophisticated tools to isolate and resolve.
The servers use static mappings to the same external DNS servers.You’re so pleased with the ease of the upgrade that you forget to reconfigure the TCP/IP settings of the newly upgraded DC to point at itself for DNS. (If you’ve installed the Support Tools, you can run Netdiag /fix.) Now change the DHCP scope option to point clients at the new DC for DNS, then chase down any statically mapped servers and desktops and correct their DNS entries.You also forget to reconfigure the DHCP scope options so the clients still point at the ISP’s DNS server instead of the new DC. The DC doesn’t register SRV records in the new DNS zone and the clients wouldn’t be able to find them, even if it did. Read the rest of the column for suggestions about resolving Internet names. It accepts the flat name from the user then appends a suffix to form a FQDN it can send to a DNS server.And here it is: The GPO which does the exact same thing as the netsh command, or checking the checkbox Use this connection’s DNS suffix in DNS registration is located below Computer Configuration DNS Client.It’s called Register DNS records with connection-specific DNS suffix.
