No help at all I'm afraid, as the web interface shows me this :
Cisco Systems
Accessing Cisco C827 "Router"

Telnet - to the router.

Show interfaces - display the status of the interfaces.
Show diagnostic log - display the diagnostic log.
Monitor the router - HTML access to the command line interface at level 0,1,2,3,4,5,6,7,8,9,10,11,12,13,14,15
Connectivity test - ping the nameserver.

Show tech-support - display information commonly needed by tech support.

Where do I go from here? As previously mentioned, complete Cisco novice.
You can't just turn off the server, though you can disable the DHCP service which will stop server, client and DHCP relay processes.

If you want to stop the router from allocating internal IP addresses you need to remove the DHCP configuration entries.
Telnet to the router and login. Enter "enable" and password if prompted.
Enter "show run". Hit enter to display next line or space to display next page. I suggest you copy and paste the whole configuration into a text file as a backup.

Enter "show run | include ip dhcp".
Enter "configure terminal". For each of the lines that were displayed, you enter each (cut and paste) but prefixed with "no".
For example
no ip dhcp excluded-address
no ip dhcp pool mypool

Enter "end". To save the configuration, enter "copy run start".
