Re: Fixed Lease DHCP Doesn't Work After Connecting Different Netwo

What do you see in ipconfig /all after you try this? What's the DHCP server
address? Shouldn't be the one on the network you aren't connected to!

I even tried "nuke-ing" my network stack using
the command on Scott Hanselmann's blog, but I still had the incorrect
IP. The only way that I found that works is speciying a fixed IP and
then changing back to DHCP.

Any idees?

What about repairing the connection, as I suggested?

One way around this would be to do an ipconfig /release *before* shutting
down on 'the other network" ....then when you boot up in your office you
should getthe correct IP.

Everytime I use my laptop on another network and get leased an IP
and then return to the office I don't get my "fixed lease" IP based
on MAC address. The only way to get my assigned IP again is to
assign myself a fixed IP and then change back to DCHP. Somehow,
these actions reset something so that I get leased the correct IP
again..

Why is this happening and who can I fix it without assigning myself
a fixed IP, applying and changing back to DHCP.

BTW - I'm not using wireless.

Thank!

This is normal but you're making life harder than you need to to fix
it. Either use ipconfig /release ....ipconfig /renew, or repair your
connection by right-clicking on it.
