hi,
I've started getting to grips with setting up dhcp services on a cisco router in PT. I also set up a dns server.
All seemed to be working fine but i noticed on SOME of my host pcs although they received an IP address and subnet mask via dhcp, they did not receive the Default gateway(DF) address nor the dns server IP. It seems some receive all the details but others dont. I have tried using the ipconfig /renew command as well as rebooting the hosts and router but no luck. I am able to ping from a host to the default gateway and back again. I have another subnet connected to this network and the PCs that have a DF can ping the other network but the PCs that dont have a DF can't. The big question on my mind is why are some PCs getting all the DHCP settings and others not? puzzled
Here's my running config. Help much appreciated.thanks
