Static IPs 3

[kurtismonger]

I recently(last weekend) did a fresh install of 2000 Server on my network server. I setup a domain with the same name as before and installed and configured DHCP, DNS and AD. All the users were setup in AD and I tested logging them into the domain, printing, etc. Everything worked perfectly.

However, since Monday, 7 of my 15 users have logged in with limited connectivity. By that I mean they enter their password for the domain and appear to be logged in, but are unable to use network resources like shared files, printing, Internet, etc. If I set the client to a fixed IP, everything works fine. Obviously, I can switch to fixed IPs, but I don't really want to especially since I don't understand why this is happening.

I did not have this problem before the reinstall. Reinstall was required due to some licensing issues. The previous OS was 2000 SBS.

Did you authorized the DHCP server?

Is DHCP issuing the correct DNS address?

Both of the above are excellent suggestions.

Verify that DHCP is indeed authorized and giving out addresses. Check the scope options and make sure that they are pushing out INTERNAL DNS servers and not your ISP DNS. Make sure that the DNS Server has the ISP DNS configured on the Forwarders tab.

I hope you find this post helpful.

Wow, I am truly a stupid person. Can't believe I missed that after the dozens of installs I have done.

Thanks everyone!

So out of curiosity, which part was incorrect?

I hope you find this post helpful.

The DHCP server was not authorized. Here is what happened if you are interested.

This server was previously running 2000 SBS that somehow was not installed properly so that I couldn't add any licenses to it. It was however functioning as the DNS, DHCP, DC, and Active Directory server without issue. I just kept getting the pesky license exceeded message, which in SBS prevents further users from getting access to network services. I have about 15 client computers on this network.

So I reinstalled it with a copy of W2K Server that I had from another older, decommissioned server. I chose plain old W2K Server, since I didn't need any of the SBS features and the 10 licenses I needed were much cheaper than SBS licenses.

Before starting I turned off all my clients and then brought them back up after the install was done and I had configured all my services. The clients all had earlier leased IPs from SBS server before I took it down. When I brought them back up and tested connections, etc. everything worked great. However, over the next week and a half or so, the IP leases on those clients started to expire and they went looking for new ones. DHCP was setup correctly, except for the authorization, so it wouldn't give them a new one.

A simple fix, but I didn't spot it until you jogged my memory.
