We have users who travel from one location to the next on a regular basis. The user receives an IP at Location A and all is fine. The user then goes to location B but does not receive new IP. release/renew does not work. Keeps the IP from location A. Deleted IP from Win 2003 DHCP server but still keeps IP from location A. Laptops are setup as Auto IP Auto DNS. Location A and B are on different subnets using Superscopes. If the user is homed at Location B same issue but with location B ip not releasing. If IP manually inputted all is fine.
