Apple Remote Access MultiPort Server - Manual (Page 6)

SNMP AppleTalk Transport v.1.0 is not compatible with the MultiPort Server.
If you have SNMP AppleTalk Transport v.1.0 installed, remove it. If you
intend to use SNMP network management with either the Internet Router or
the MultiPort Server, install SNMP AppleTalk Transport v. 1.1 after installing
the Internet Router and before installing the MultiPort Server.
AppleShare
The Apple Remote Access MultiPort Server and AppleShare v. 4.0.1 or later
can run concurrently on the same Mac OS computer. They will share the same
Users & Groups Data File.
Macintosh file sharing
The Apple Remote Access MultiPort Server cannot run concurrently with
Macintosh file sharing. If you install the MultiPort Server on a Mac OS
computer on which file sharing is enabled, you will be asked to convert the
Users & Groups Data File. After conversion, only the MultiPort Server and
AppleShare 4.0.1 or later can access the Users & Groups Data File.
