Description:
The DHCP/BINL service on the local machine, belonging to the Windows Administrative domain TPCHS.local, has
determined that it is not authorized to start.  It has stopped servicing clients.  The following are some possible reasons for this: 
This machine is part of a directory service enterprise and is not authorized in the same domain.  (See
help on the DHCP Service Management Tool for additional information). 
This machine cannot reach its directory service enterprise and it has encountered another DHCP service on
the network belonging to a directory service enterprise on which the local machine is not authorized. 
Some unexpected network error occurred.

Anyone have any idea's on how to fix this?

Answer 1

The error message you have says that your DHCP server cannot reach your DCs. Please make sure that they are reachable and that traffic to them is not blocked or filtered. Also, make sure that your DHCP server points to your DC/DNS servers as DNS servers.
Another thing is to check your DCs and AD replication health status using
dcdiag and repadmin commands. My article here and recommendations could help: http://www.ahmedmalek.com/web/fr/articles.asp?artid=23
