That is the command to release the IP on the CLIENT. I was talking about removing an issued lease from the DHCP SERVER. And, releasing the IP from the client, AFAIK, doesn't mean the lease is cancelled, just inactive. If you renew the IP during the lease term (ipconfig /renew) you ought to get the same IP number. The MAC is still associated with that IP and, in his case, the name. According to the Microsoft DHCP Server documentation I just checked, the lease is valid until the expiration date. So, if you have a three year lease on an IP, it cannot be issued to a different MAC address until the three years are up. I haven't checked the RFCs for DHCP, but I doubt there is any way for the client to force a lease to expire. The point of DHCP is that the DHCP server is configuring the client, not the other one around. -- Dan Jenkins ([EMAIL PROTECTED]) Rastech Inc., Bedford, NH, USA --- 603-624-7272 *** Technical Support Excellence for over a Quarter Century _______________________________________________ gnhlug-discuss mailing list [EMAIL PROTECTED] http://mail.gnhlug.org/mailman/listinfo/gnhlug-discuss
