DHCP Not handing out leases 4

[PhilFoster]

My server is configured to provide file, print and internet sharing (the latter through an ISDN TA - no router).

I've configured a scope in DHCP - 192.168.0.1 to 192.168.0.24 - two reservations: one for the server on .1 and one for my laptop on .2

DHCP server doesn't (according to "Address Leases" in DHCP console) hand out leases to my other (w98) workstations, but all the workstations get access to the LAN and internet.

Also, most of the workstations get IP addresses outside the range of the defined scope (e.g 192.168.0.64).

I'm totally baffled by all this. Can anyone shed any light please?

Zoey In option 15 do I put in my domain name? What do I put in as the WINS/NBNS option? (this is all getting way over my head....
I thought I understood all this, but I'm feeling like a 5y/o trying to do calculus (yes, I know some 5y/o can do calculus )

Phil,

015=WS-ONE.mydomain.local
(You can also confirm this by going to a command line from the Primary Server (The Primary DNS Server) and typing ipconfig /all and this will list your DNS server. I'm just going by the WINIPCFG info you gave me but I do believe this would be the domain name you enter

For WINS. Have you already installed WINS on your server? If you did you will need to note the IP Address.

044 = IP Address of WINS Server
046 = 0x8 will be the option you enter for the node type

Let me know how you make out. You are doing fine. It is just like anything, if you don't work with something it can seem complex.

Phil,

Correction.

015=mydomain.local

tow other notes of interest.

You note there is no router in your network?

Therefore in DHCP you will not need the router option 001

Is this a Peer-to-peer network? If your still having problems please list more detail about your network. At this point I will assume you do not have a router on your network. And if you do not have a router on your network you will not need a default gateway specified.

I also noticed on the display from the WINIPCFG from your windows workstation you have the following:

IP Address. . . . . . . . . : 192.168.0.128
Subnet Mask . . . . . . . . : 255.255.255.0
Default Gateway . . . . . . : 192.168.0.1
DHCP Server . . . . . . . . : 192.168.0.1

From above I see a default gateway specified.

On your server I see the following:

IP Address. . . . . . . . . . . : 192.168.0.1
Subnet Mask . . . . . . . . . . : 255.255.255.0
Default Gateway . . . . . . . . :
DNS Servers . . . . . . . . . . : 192.168.0.1
(From above you do not see a "Default Gateway&quot.

If you do not have a router where is the client picking up the Default Gateway address? I wonder if this may be causing any problems. You are trying to cross a router that does not exist from the client. If the default gateway is suppose to be there then you have to go to your TCP/IP static IP settings on your server and include 192.168.0.1 in the Default Gateway.

set your scope to 192.168.0.3 - .024. your reservations are conflicting possibly because you are trying to reserve the same machine DHCP is on. Ditch the reservations and adjust your scope if possible, and assign static to use below the scope.
make sure to add your gateway info to hand out to the client.
reboot the '98 machines, or at the DOS>, IPCONFIG /RELEASE_ALL, then IPCONFIG /RENEW_ALL.

Make sure ICS is not already assigning DHCP. If you need ICS, then you probably do not need DHCP running. ICS acts as the DHCP server.

hope this helps.

Lance By ICS do you mean Internet Connection Sharing?
I do have this running on the server. Should I turn this off?

 

[PhilFoster]

Oh, and I do need Active Directory and DHCP on the server to run DoubleTalk on the Apple.

OK, I've taken ALL the steps advised above - including reinstalling TCP/IP on one of the w/s. and still no joy.

The w/s I reinstalled TCP/IP on can no longer see the LAN or net - it says "The DHCP Controller is not available" when I re-boot.

The list of leases in the DHCP console now has one of the workstations: WS-ONE on 192.168.0.5 (this is the first physical machine on the LAN - the first port on the hub), my laptop (which is reserved, and must remain so as I'm going to install an eMail server on this) on 192,168.0.2 and two leases that don't display a name, only an IP address, ie 192.168.0.3 & 192.168.0.6
None of the machines on the LAN have these IP addresses.
FX Sounds of hair being ripped out (and I can ill afford this )

w00t! Fixed
I just found the problem.
After making all the changes suggested (which I most humbly give thanks for) I restarted DHCP. Then I right-clicked on the root of the DHCP tree and selected "Manage Authorized Servers" and to my surprise, there were two server.mydomain.local entries - one for 192.168.0.1 and one for 193.195.124.209 (the IP address for the ISDN TA) this had somehow become the active DHCP server????
I didn't create it and how it got there I don't know. Anyway, after unauthorising it and authorising 192.168.0.1 the leases for all the workstations were handed out. And everything is hunky-dory (well, except I can't see the

the iMac - but that won't take long to fix).

I guess if I've learned anything here, it's not to make assumptions - the darn IP address of the TA was sat staring me in the face in the DHCP console tree, but all I saw was server.mydomain.local.

Once again, many thanks - I owe a few beers here!

Regards - Phil.

Good going Phil. Would not have thought there was a second DHCP Scope Active. We all learned something here. This was a great discussion.

Take care.

I will take a Heineken please!!!!

Since I'm not running DHCP, I've definetely learned things here. I'm setting up a home network and I'm going to run it there. Great info. Glen A. Johnson
