Clients can't log on

I have a 2003 Small business server.  After reading last week questions in here I  realized my server was not completely set up (it didn't have some tools ie Server manager)  Anyway I re installed server rebooted then no  one could log on.  THey would get a little yellow box with limited and no interenet connection and they were getting strange IP addresses.  Any Suggestions?

It sounds like your DHCP service is not running or installed properly.

If you are not familiar with how this is done, please see this site:

No DHCP works find

Well, you described getting weird addresses and having limited connectivity - so this indicates that the client is using APIPA.

What IP addresses are they getting? 169.x.x.x indicates they are not getting DHCP addresses.

169.x.x.x is what they are getiting.  It's strange to because the day before everything worked.  Now it's just yellow over the connection and I have to physically enter IP address and DHCP .

is the dhcp server working? does it have a blue ! on it? if so then you ran out of addresses. If you set your lease time high this will happen. 169.x is the addres sall adapters get when dhcp/static ip is not setup.

Netman66Commented:
Re-Authorize your server.  Right-click the server in DHCP and select Authorize.

Make sure your scope is showing the green arrow.

DHCP is already authorized.  Anything else ?

Netman66Commented:
Give one of your PCs a static address that is in the DHCP scope.  Try pinging the server to see if you can reach it.

Have you changed anything on the LAN lately?  Is there a router between the client PCs and the DHCP server?  Have you created any VLANs and accidently caused the server end up in a different network?

I can ping the server.  There is a router a DLink 604 and we only have one network card for the internet and network. No VLans

Netman66Commented:
Sounds like Automatic Updates has installed SP2 on the clients.  You'll probably need to turn off the Firewall to see if you get addresses.  If so, you may need an exclusion.

Tried that didn't work.  I think it has something to do with DHCP  Whenever I look at  it it's stopped.  I also saw something about  DHCP can't work because no static IP address?  It keeps getting stranger every day.

Netman66Commented:
Your server must have a static IP address - yes.

Open up your scope and delete all the Leases - then try to reboot a PC.  It almost sounds like you're out of addresses.

Where do I put a static IP address -

Not out of addresses but I will delete the scope and reset iup

Netman66Commented:
The static address should be on the server's NIC - it must be in the scope of addresses you are using for the network.  Set up a new scope, give your server the first IP in this scope then setup an exclusion within the scope for the server's new IP (this way it won't be given out to a client PC).

Advise.

I'm sorry you misunderstood me I have a separtate static IP address other than the one on the Nic it is from my ISP and I already have it set up the way you suggested.

Netman66Commented:
So your server has 2 NICs?  One NIC connects to your ISP with a static address and the other to your LAN with a static address??

If so, make certain in DHCP MMC that the properties of the server have it only servicing the internal (LAN) interface.
