Title: dhcp assignment, reassignment, renewal
Post by: Brian Rafferty on October 30, 2000, 11:39:19 PM

I have an NT4.0 network with the e-smith as dedicated server gateway.  Also it is the DHCP server.  Several computers have been assigned the same IP address. How do I correct this?

That probably means that you have more than one DHCP server on the network -  have you checked that all your NT machines have the DHCP server disabled? If that is not the reason, then your e-smith server at some stage lost its leases file - perhaps you reconfigured something. If that has happened, releasing and renewing the leases on each workstation will correct the problem.

If the nt server is not the dhcp server and it's not, how do I release and renew the leases on the e-smith server?

No, you need to release and renew the leases on the *client* machines - one or both of each pair which have been allocated identical IP addresses. The server can't fix this problem.

The way you could renew or clear the ip assignments is using winipcfg(in win 98) and ipcfg (win NT)

Gentlemen,

I understand about using the release/renew option under win9x/nt/2k; however, my dhcpd.lease file is showing all the leases, including the expired.

How do I clear the dhcpd.lease file so that my cgi script (lanlord.cgi) doesn't report on inactive/expired leases.

Thanks,

Patrick
