Event ID: 11154 Source: DnsApi

The system failed to register network adapter with settings:

   Adapter Name : <adapter name>
   Host Name : <host name>
   Adapter-specific Domain Suffix : <domain suffix>
   DNS server list : <ip>
   Sent update to server : <ip>
   IP Address(es) : <ip>
The system could not register the DNS update request because of a security related problem. This could happen for the following reasons: (a) the DNS domain name that your computer is trying to register could not be updated because your computer does not have the right permissions or (b) there might have been a problem negotiating valid credentials with the DNS server to update.

You can manually retry DNS registration of the network adapter and its settings by typing "ipconfig /registerdns" at the command prompt. If problems still persist contact your DNS server or network systems administrator. For specific error code information see the record data displayed below.
In my case, I noticed the <domain suffix> area had a different name than the server name. Example: Adapter-specific Domain Suffix : I searched through the registry and found "AlternateComputerNames" entries containing this "unknownservername" under:
After clearing these entries, the event warning ceased to occur.
