DHCP Forced Renew


G

Guest

Our network uses DHCP to assign the addresses and set the default gateway to
10.0.0.1 (router), however our network design is going to change, with a L3
swtich replacing the backbone. The switches IP is 10.0.0.4, if we add that
as the default gateway it could take up to a week to get all clients up and
going. We do not want to change the lease duration or go from one computer to
the next typing ipconfig /renew. From the DHCP manager how do you force all
clients to renew all their information, or if we change that value it will
work on a next boot regardless of the duration of the lease timer?

There are probably quite a few different ways to do this. I am no expert on
DHCP, but how about:
1. Changing the default gateway setting, and
2. Delete all the leases.

AFAIK, deleting leases does not affect users until they log off. If you do
that one night, then next morning when your users log on, their lease will
be renewed with the new settings.

HTH,

We don't do it the "hard way", we do it the *Right Way*..... :)

BTW, did I ever tell you the 6 most frightening words a tech support
person can hear??

"Never mind, I fixed it myself!"............. ;-)

so please tell me how chaging the IP address of the switch to 10.0.0.1 is the
*wrong way*?
