Sbs 2003 Dhcp Not Working

NOT!I have already assigned static addresses so at least the network works while we can hopefully come up with some kind of fix.I discovered the problem following a lease expiring which Can not start the DHCP Service in Windows SBS 2003 ? That method will take forever and a day, but if no one can think of another solution, that may be our only option! 0 Datil OP Chris Seiter So it looks like it's not a network switch error The only thing I can think of is there's a rouge device on our network that's handing out DHCP as well? http://johnfladung.net/sbs-2003/sbs-2003-rww-not-working.html

If your client cannot obtain an IP address is will fail back to an APIPA address in the 169.254.x.x subnet. You could also install wireshark or similar on the SBS and a test laptop to get visibility of the dhcp requests. If that's pointing to the wrong address, you will see the symptoms you are seeing. What am I doing wrong?

The server then automatically forwards requests it cannot resolve locally. It is recommended to add longer leases for a fixed network (in the office for example) and shorter leases for remote connections or laptop computers. The issue might be on the NAT config. __________________ Networking Articles & Tutorials Preposting Requirements 05-05-2010, 10:32 AM #7 djaburg Moderator - Microsoft Support Join Date: May ISA firewall is a good example.

This is because ISA will try to resolve the broadcast IP to a URL to make sure it is not blocked. That's the quickest way to have an issue.

I amended the question.They should have 192.168.17.? http://www.techrepublic.com/forums/questions/dhcp-not-working-on-sbs-2003/ now you say that works perfect, (conclusion is that DHCP is functioning correctly) you say you connected the server to a switch with one pc connected and it works correctly (

A couple of months ago I rolled a second domain controller on a client's network and configured it to serve DNS and DHCP. This new range also saves me from having to put in a reservation for the printer at 192.168.1.13.

To do this, I recommend that you do not allow the DHCP server to provide leases within a range of IPs. Tuesday, April 01, 2008 12:26 AM Reply | Quote 0 Sign in to vote wrness,Good problem eh?

Followed by the change of ip address, I also added the new subnet to AD sites and services, change DNS and change DHCP scope. weblink and staring at it lots! 2 Mace OP Martin2012 Jan 9, 2012 at 11:14 UTC I'd also check no other dhcp server is sitting out there.

I've seen cases where the users bring in their own wireless due to the IT admin's onerous rules and it causes havoc.  One other thing, are you getting APIPA addresses (169.xxx.xxx.xxx addresses) In this example I have excluded a range of IP addresses, 10.0.0.100 to 10.0.0.110, and a single address, 10.0.0.150. Check your switch for changes to the Vlan i.e. It does.

Reason for not getting the leases from the SBS DHCP eventhow that with static ip's on the clints nic's i could connect and resolve names etc is because in the registry http://johnfladung.net/sbs-2003/sbs-2003-iis-not-working.html As noted, you needed to manually assign a static IP on your server.

There does not seem to be a physical problem, as I can set a static IP address that will work just fine. In DNS, that's called the scope, and you may have told SBS to hand out 120 addresses, and you've now filled up that list.
