Problems with W2k3 DHCP Server
Greetings, my only DHCP server seems to have failed as it is not giving out IP addresses. On gandering into my System Events, I see a few that are constantly occuring that could explain the problem, but I have no idea what they are saying or how to fix them:
1) The DHCP server failed to see a directory server to authorize it. (This is the directory server as far as I know)
2) The DHCP/BINL service on the local machine belonging to domain xxx.xxx has determined that it is not authorized to start.
Any ideas on how to remedy this?

See this technet article for your situation. I could write this all in my own words but it would be redundant. You need to ensure there is a network connection between your DHCP server and your Active Directory server. The second message is related to the first, so if you resolve the network issue you will not see either message.

Let me know if you need further clarification.

I see Unauthorize.
Grand, work on the link baller119 sent, looks like a different issue...
In the console is everything Green?

Alright, if I ping the computer name from the DHCP server (itself) the address that is coming up is a IPv6 address. If I ping that computer from my work station what is coming up is that the ping request could not find the host. Ping will work with the IP address of the DHCP server though.
IPv6? Is this not a 2003 server?
If ping isn't working from workstation then something wrong with DNS...what was changed on the server lately?
Open DNS console and right click servername, properties - is the default ip address for the server ticked to 'Listen on ip addresses'

Although the Guid DNS name

be resolved, the server name (library2.wscalibrary.edu) resolved to
the IP address (192.168.100.154) and was pingable. Check that the IP
address is registered correctly with the DNS server.

The only thing that was changed recently is I tried to install WinSnort on this machine.

Right...never installed snort on a DC before so not sure...
Run these commands to see if we can fix things...
ipconfig /flushdns
ipconfig /registerdns
dcdiag /fix
then
net stop netlogon
net start netlogon
See if dcdiag then reports all is ok again...

That 100.44 should be 150 I think

I actually have two different domains, and two different servers that handle DNS. I have .44 which is on a different domain and has all the entries for both domains in it and then I have .154 (this machine) that handles DNS and DHCP.

.254 is a server that handles my phone system and then pushes all traffic to .1. So, either Gateway is correct.
2 different domains? Not sure I follow...
Can you draw this up for us? Sketch it on paper or something so we can see this thing from top level?
Both your servers are showing dns suffix of
wscalibrary.edu
So how is this 2 different domains?

Alright,
.150 (Library1-Win2k) and .154 (Library2-Win2k3) exist on the domain: wscalibrary.edu.
I have another domain on site that is wscal.edu. .44 is a Win2k8 server that belongs to the wscal.edu domain.
In the past all machines in both domains have been getting serviced for DHCP by .154. For some reason within the past week (I was out of the office Thursday through Monday) DHCP failed to provide IP addresses to my users. My address leases were set at 7 days and the last addresses were set to expire on June 2, leading me to think that the failure happened yesterday, when no one was here or sometime when I was not here.

smckeown,
What I am saying is DHCP stopped working within the last week.
8.8.8.8 was added earlier AFTER the issues had occurred.

Ok...
I understand DHCP stopped working...why did it stop working...cause replication failed...and failed...and finally your dc(the working one) was not contactable...in which case DHCP said 'oh...can't find a domain' - therefore it stopped working
So...we need to get replication working to fix this(sorry if I sound condescending here, but I'm simply trying to get this resolved based on what your results of ipconfig/dcdiag have shown)
Adding 8.8.8.8 isn't going to help things, its going to add to the misery(Google knows nothing about your internal dns layout so adding that isn't a help)

Thanks for the help. I did not take you to be condescending. I think I was thinking about a different issue than you were, so I am sorry for not trying to fix the problem that you were (I was thinking that they were completely independent of each other). I have done what you instructed and ran dcdiag /fix again and everything passed. I honestly think that what it came down to was the time was off by an hour on the servers so they stopped communicating.
Excellent...and yes time issues could have been the cause of the main issue...
Glad we managed to get it resolved in the end...cheers ;)

Not sure why it would have been unauthorised though...
