DHCP Superscope problems

[JayIT]

I have DHCP running on my W2k Domain with scope 1.

I created a superscope and added a scope.
My DHCP server as an IP 192.168.0.1
and DNS are 192.168.0.1 and 192.168.0.201

So now I have scope 1 192.168.0.1 to 192.168.0.254
And scope 2 192.168.1.1 to 192.168.1.254
I set scope 2 with the same DNS servers and gateway that scope 1.

For some reasons the IP’s that are leased from the scope 2 can’t browse the network and can’t go online.


Thanks for the help

What does ipconfig /all tell you? I know it sounds simple, but sometimes it's the simple things that are goofy. Good luck. Glen A. Johnson

ipconfig /all tels me the right info.
ip 192.168.1.2
dhcp 192.168.0.1
dns 192.168.0.1 and 192.168.0.201
right subnet mask
It all looks good...

Is that from a server or a problem machine. Can you take a problem machine and give it a fixed IP and see what happens? Good luck. Glen A. Johnson

that ipconfig /all results are from a work station. that same work station works fine with a static or dynamic IP in the range on scope 1

but when getting a dynamic IP, it cannot browse the internet or the network.

How about a problem machine? That's where we need to look. Give a problem pc a static ip and let us know what happens. Glen A. Johnson

36mis,

You said, "I set scope 2 with the same DNS servers and gateway that scope 1."

Unless I am missing something here how can you expect a client with an IP address in the 192.168.1.x/24 range to communicate with a DNS server or gateway in the 192.168.0.x/24 range?

I must be missing something here...

Maybe I am missing something but my understanding is that superscopes allows you to use differents ranges.

I'm I right?

 

[JayIT]

oooops, wrong link.

this one is the right one

What about the fixed ip? Glen A. Johnson

36mis,

Well admittedly this is not an area of expertise for me but I would think that if you have your router configured with multiple addresses to support superscopes, than the scope options for the 192.168.1.x should hand out a default gateway in that subnet, i.e., 192.168.1.1 and the scope options for the 192.168.0.x should hand out a default gateway in that subnet, i.e., 192.168.0.1.

Any superscope gurus out there?

Patty

 

[JayIT]

Fixed IP in range 192.168.0.x will work
fixed IP in range 192.168.1.x will not

 

[GlenJohnson]

Good, now we're getting closer. Set up a machine with dhcp on the scope that doesn't work, and ipconfig /all the problem pc. Good luck. (FYI, GrnEyedLdy is correct. Subnetting has to be the most difficult thing to figure out. At least it is for me. I still don't have a real good feel for sub-netting. Need to do more homework.) Glen A. Johnson

[JayIT]

I did that already, and like I said earlier the results are good

ipconfig /all tels me the right info.
ip 192.168.1.2
dhcp 192.168.0.1
dns 192.168.0.1 and 192.168.0.201
right subnet mask

Sorry, thought you said that a good box. Have to look elsewhere. Glen A. Johnson
