Hi,

I want to add an ip exclusion range containing five ips that have to be used by only one department.   they need 5 ips reserved for them for some dbase accesses.

What will happen if some computers have one of the ips in the ip exclusion range i create for e.g.: 192.168.10.195 - .199

Will they keep on using one of the ips in that range or will they automatically request a new ip on their machine?

Thanks

They will keep the IP until their lease is up and they begin requesting a IP renewal.  The computer will begin tryiing to renew the IP when 1/2 or the lease is up. So if your lease duration is 30 days it will begin renewing at 15 days.

You should use 5 static IP outside of the DHCP range for this purpose.

Or you could just delete the lease and force a renew.

If you don't want to wait for the 1/2 lease time, you could use telnet or psexec to remotely force the client to renew by running ipconfig /renew remotely.

Say a machine has 192.168.10.195, delete the lease from DHCP, and run the following command:

psexec \\192.168.10.195 ipconfig /renew

The client will be forced to get a new address because of the exclusion.
