DHCP Issues
Referring to the Figure 84 above, note that it says:
Dhcp enabled. . . . . . . . : Yes
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 IP Address Change in Chapter 5.
To avoid having to make Message Server IP Address changes, assign the RAID
PC a permanent IP address. See your IT Manager for guidance.
