We have several District offices each on Frame-Relay with each office on DHCP with their own private 10. IP adress. When "User A1" goes to Office B2" they connect to the LAN/WAN via DHCP. Then when "User A1" retuns to their office they can't connect to the LAN/WAN. The computer won't let go of the other offices IP address. I try IPCONFIG /Release with no luck. I end up hard coding the IP address into the TCP/IP with that offices IP address and it works. Then I remove the hard coded IP Address and they get the DHCP address they need. Whats up with that?
