I have a domain that is shared by two companies. Company A is on 192.168.1.x and is obtaining those IPs from server A. There is a router that has a 192.168.20.x that company B is behind. This router is set to be the DHCP server for the .20 subnet. If the computers from company B are shut off, when they are turned on they obtain an IP from server A, which is 192.168.1.x and not the router that they are behind. After they are turned on, we can do an ipconfig /renew and then get a .20 address. Why wont these computers obtain a .20 when they boot?
