DHCP Issues
Referring to Figure A-1 above, note that it says Address Type: Assigned by
DHCP. This means that a DHCP server gave this IP address to this PC
when the PC connected to the network. DHCP stands for Dynamic Host
Configuration Protocol and refers to software that allows a file server to
assign IP addresses to computers on the network.
DHCP is very helpful in reducing the number of IP address a company or
organization requires. The DHCP server assigns an IP address to a
computer as it logs onto the network. The IP address will remain the same
until the computer logs off or disconnects for any reason, such as a power
failure. When the computer logs on again, it will receive a different IP
address.
Because IP addresses are subject to change when a DHCP server is
involved, make it a point to maintain the RAID PC network connections at all
times. When a disconnection happens for any reason, you must find the new
IP address and enter it into the Message Server. Instructions for doing this
appear under Message Server Address Change in Chapter 5.
To avoid the problems of changing IP addresses, assign a fixed IP address.
