Name Resolution

If your network does not have DNS, you can also assign hostnames on a Windows platform n the

file

%windir%\system32\drivers\etc\hosts

. Here, you must assign a hostname in

addition to an IP address in the system. Here are some example hosts file contents (including two

commented lines where you would have to remove the # sign to make them effective):

# 102.54.94.97 rhino.acme.com # source server

# 38.25.63.10 x.acme.com # x client host

127.0.0.1 localhost

This software supports installation to

only

the local file system. Avoid installing to shared drives.
