Change subnet mask for Domain Controller and Exchange 2000 server
Posted on 2006-05-16
Servers: Both Domain Controllers, Our DHCP and DNS are running on Linux Servers.
1 Windows2000 server sp4, running AD,Exchange 2000
2 Windows2000 Server SP4, running AD,Bkupexec,WSUS, Mcafee Protection pilot
Ip address range: 192.168.1.0 255.255.255.0
We would like to change our subnet to 255.255.255.254, this will give us more addresses. We have several new servers joining this network and with wireless networks, failover, etc we may start to run out of addresses. We will only be a few addresses into the range, but it will solve potential problems.
Most of our linux machines and all our windows desktops now use the 254 subnet mask, DHCP is configured for that and DNS has the reverse arpa 192.168.0 DNS lookup for the new network has been created. Can I just change the subnet mask on the 2 Domain controllers, bearing in mind that one of them is running Exchange 2000 server?
