Why did You accept the job if You knew You can't diagnose such problems that would definitely come in?
I hope this comes in handy;
Start, Run, CMD
Reset WINSOCK entries to installation defaults: netsh winsock reset catalog
Reset TCP/IP stack to installation defaults. netsh int ip reset reset.log
If that doesn't resolve the problem, do this.
ipconfig /all << --- copy these results and post them back here
netsh diag gui <<--- not any FAILED entries and post them back here
exit
//Note: Bold Text are Commands!!

Have a look in the DHCP scope on the server and check the status of the leased IP addresses pool. What are the status of the lease recorded in there. Do you have any free IP addresses available in your scope. If not, could you possibly expand the scope or create a new one.
Are there any recent changes on your network - is the DC/DHCP server behind a firewall and are there any recent firewall rules changes?
You could also try sniffing the DHCP lease process between a client and the DHCP server. Try using etherreal for this. You need to eliminate where the DHCP lease process is breaking. Are you clients succesfully sending out DHCP discover messages, are these getting to the DHCP server, how does the server responding - is it making a DHCP offer?
Are there any specific error coming up on your clients that are not able to renew their lease. If you do an ipconfig /all on these clients, do you have an APIPA address (169.254.x.x) returned as the client IP address?
Check the system event log on the server for any related error messages.
Also what is the system event log on any of these clients saying?
Your answers to these would help further troubleshooting
