Question : DNS Error 4000 + 4013 and DHCP error

Hopefully all these errors are related to each other:

DNS ERROR:

for the last 4 days have been recieving errors 4000 and 4013 ive looked at
http://support.microsoft.com/default.aspx?scid=kb;en-us;Q316685

but has made no difference

users for example cant access \\mycomputername\ but can access it via \\192.168.....

DHCP Error

running DHCP on the same box, open up dhcp says "Not authorised" right click to authorise but instead says "Unauthorise"
have a scope setup machines arent getting address,

dhcp service is running (have tried restarting it with no affect)

please advise on what i should do
