Snafu Posted November 20, 2007 Share Posted November 20, 2007 Hi All Got a question about DHCP Renewing IP addresses in our office takes about a minute or so. I asked a co-worker about and he said that it's been like it forever. I've checked out the server and there's nothing weird going on with it. Any ideas? Running DHCP on Server 2k3.

+BudMan MVC Posted November 20, 2007 MVC Share Posted November 20, 2007 Are you on 1 segment? How many machines? Are you on multiple segments with IP helper addresses setup for dhcp on your routers/layer 3 switches? What should it matter if it take 10 seconds or 3 minutes? A renew of the address should be in the background anything an happen automatically when the lease gets to the 50% mark, etc. How long is your leases? How large is your scope? Is the scope full? etc.. etc.. Link to comment Share on other sites More sharing options...
Snafu Posted November 21, 2007 Author Share Posted November 21, 2007 We are one one segment with about 30 machines. IP's are leased for 8 days, and our scope is about 100 addresses. The scope is not full Link to comment Share on other sites More sharing options...
Eversurf Posted November 22, 2007 Share Posted November 22, 2007 From personal experience a minute is fine. I have seen it take longer and usually something is up with the workstation. Is it all workstations? Link to comment Share on other sites More sharing options...
compass4 Posted November 22, 2007 Share Posted November 22, 2007 This may not apply at all, but just in case... At one of my clients, I inherited a network that was messed up. DHCP clients would sometimes time out attempting to get an IP address, sometimes it would just take forever. long story short, the previous admin decided to play with VLANs. Whatever he was trying to do, was either unfinished or just wrong, and uneeded at any rate.. I ended up reseting the switches to default. It solved all the DHCP issues straight away.
