Cannot start DHCP on Windows SBS 2003

I can't get DHCP to start on my server.
I am getting event id 1053, 1054, 1056 in the event log
1056 states to set the credentials but i can't do it in the admin tool because the server is not started and when I start it, it just stops again. I tried the command:
netsh
dhcp server 192.168.10.100d and I get: unable to determin the dhcp server version of the server 192.168.10.100
and same thing when i do the set dnscredentials

Server intenal ip is
192.168.10.100

server external ip is
192.168.1.110
192.168.1.1 GW

Router is 192.168.1.1

Some WS are getting the correct ip range 192.168.10.101-150
but others are getting an IP from the router 192.168.1.100-150

You need to disable the DHCP service on the LAN side of your router.

If SBS detects another DHCP server it will shut it's own down and this will prevent you from starting it again.
