Domain Controller Slow DNS - DcDiag Errors

Have a server 2016 DC that I need help troubleshooting. When computers use it as their primary dns, opening web page is very slow. USing googles DNS opens pages very fast. Running DCdiag produces the following: (Server names removed, also cut off due to character limit) Directory Server Diagnosis Performing initial setup: Trying to find home server...
