A Macintosh client must meet the following requirements:
Macintosh System Software Release 7.1, 7.5.1, or 7.5.2 is installed.
MacTCP Release 2.0.6 is installed.
MacTCP has Ethernet selected (not EtherTalk).
Domain Name Services (DNS) are available to the Macintosh. You need to manually configure DNS correctly.
The domain name and the IP address must match the information in the /etc/resolv.conf file on the DNS server. The /etc/resolv.conf file points your machine to the correct name server. If there is no resolv.conf file, the resolver uses the nameserver on the local machine, for example:
domain companyname.com nameserver 137.69.8.2
The TCP, DNS, and UDP utilities are available for use on the Macintosh. It is advisable to also have the ping utility available for troubleshooting.
You must specify the fully qualified name of the Backup server on the Macintosh client.
