I have a problem with clients constantly requesting addresses at the moment, causing all sorts of odd problems.

I've looked at the DHCP log and I can see LeaseTime:0 appearing throughout, however our lease time was set to 3 days, and I've upped it to 5 just to see if the value change and an unload/reload of DHCPSRVR would make the setting kick in - no joy.

I've also run a DSRepair on the DHCP server.

Any suggestions would be appreciated !
