Re: dhcp-dns problem
The reason that your static IP machines are being given a dynamic IP address
is that the pool of IP address that is being allocated also includes the
static IP address.
Example:
Static IP Address - 192.168.1.10
Dynamic Pool - 192.168.1.8 - 192.168.1.100
The PC realises that is has one static address previously and that it should
have a new dynamic address (make sure that it is not a DHCP client) and
makes a request to the server for the same IP address, which it is then
given. To give it a static IP address you have to move the IP address to
outside of the pool or change the pool.
Example:
Static IP Address - 192.168.1.10
Dynamic Pool - 192.168.1.20 - 192.168.1.100
Hope that helps
