DHCP Gives wrong subnet mask

[Guest]

I have set up a test network at home, with a Windows 2K Adv Server, and 3
clients, all running XP Pro. Everything is working perfectly, except that the
clients are getting the wrong subnet mask from DHCP. The subnet is 10.0.0.x.
I have the subnet mask set to 255.255.255.0 in TCP/IP properties. However, in
the DHCP Mgmt Console, the Server Scope Properties has the mask as 255.0.0.0
... The box is greyed out and I do not have the option to change it. I have
tried various setting with the Mask Discovery in DHCP. I have checked my
router to be sure it isnt issuing DHCP, and originally it was, but I disabled
it and rebooted everything and am stil unable to get DHCP to issue
255.255.255.0. Any hints ? Thanks !!

You can't alter the mask in a scope. You have to delete the scope and
re-create it with the right mask.

Thanks Phillip. I figured it would be something ridiculously simple I
overlooked.

You can't alter the mask in a scope. You have to delete the scope and
re-create it with the right mask.
