My PCs always get the same IP

Hi!

Here is the deal. I have 4 different VLans with 1 DHCP deserving all of
them. When I move a machine from a VLan to another, it gets the IP it had in
the first place. I tried to release the ads for the 2 scopes, but it didn't
help.

Thanks for your help!

Then your VLANs aren't implemented properly or the DHCP does not have the
scopes configured properly,...or both of those at the same time.

Well, I guess it can't be anywhere else :P
Do you have a more precise idea on where the error could possibly be?


Thanks fo replying!

Sorry,..the original post consists of only 3 sentences. I have no
information to be more specific.

I would have to know exactly how the VALNs are configured and how every
involved Switch and Router is individually configured configured to know
what might be wrong with the VLAN.

I would have to know exactly how the DHCP Server is setup both at the
network level and at the DHCP Service level (mainly how the scopes are
configured) to know if there is anything wrong with the DHCP Server.

But there are a few things I can list....

The DHCP,..it is best to just have one Nic with one IP# and "live" only on
one subnet. It should be configured with separate distinct Scopes for each
subnet (no Superscopes!)

The LAN's router needs to be configured to forward DHCP Queries either to
the subnet that the DHCP is on or forward directly to the DHCP Server itself
(depends on what the router is capable of).

The VLAN's,...I can not deal with that,..it is way too complicated to deal
with in an email message. It would already be hard enough to do if I was
physically there and could see the individual configuration of all the
device with my own eyes. I'll just have to leave it to you to determine
that that is correctly configured.

ok...so I shall check all the configurations between my pcs and the dhcp...I
guess I have no choice if I want to get it solved :P

Thanks again, your clues were very helpful considering the amount of
information I could give!
