Changing Hosts File Entries
Complete the following steps to map computer names to respective
unique IP addresses on both Servers.
1 . Use Notepad to view the Hosts file in the directory location:
C:\WINNT\SYSTEM32\DRIVERS\ETC.
2. You must enter the desired computer names and respective
unique IP addresses on a separate line for each Server as shown
in the display above.
These names and addresses must be included in the Hosts file
and resident on each Server and Client.
ATTENTION
!
To support redundant Servers (Primary/Secondary),
you must identify all computer names and respective
unique IP addresses in the Hosts file and be sure
they are resident on each ProcessLogix Client.
Use the DOS command >IPCONFIG/ALL<, or access
TCP/IP Properties through the General tab in the
Local Area Connection Properties dialog box to
obtain IP addresses for all configured components.
