I have a LAN with about 20 PCs (DHCP assigned) and a domain controller (static IP). The LAN has been relatively stable, but lately for some reason the PCs are starting to get assigned an IP address different (10.0.1.x) from what the DHCP server range is assigned to use (192.168.0.100-199). I have had the Comcast router changed out thinking it may be the problem, however it did not resolve the issue. There are also 2 Apple Express APs that provide wireless access to 192.160.0.x and one that provides guest access to a 192.168.1.1, 255.255.255.128 network. All the APS appear to be working properly. I am not sure why this occurring and have not seen any errors about more than one DHCP server on the network. Any suggestions would be most welcomed regarding where to start or a resolution. - Thx HBee
