The subject says it all.

I have five Windows 2003 servers, each running various business apps
including a Manufacturing Systems, Exchange Server 2003, a separate SQL
Server 2005 box.

I have roughly 200 hosts, with a variety of print servers, wireless access
points etc. I have one ADSL connection, which is the default gateway on all
machines.

I am running Active Directory on all servers with the DHCP scope ranging
192.168.50.1 thru 192.168.50.254 with a subnet of 255.255.255.0

Print servers, wireless access points and the router all have reservations
in the DHCP scope.

The problem.

I need more IP addresses.

I am looking for a step by step guide to adding another subnet to the
network so that all hosts on the new subnet can speak to the existing
servers and share the ADSL connection.

Thanks in advance
