The Macintosh file-sharing service built into Windows transfers files very slowly compared with Windows' native file sharing. Group Logic's Extreme Z-IP 2.01 more than doubles TCP/IP file-transfer speeds for Mac OS 9 and OS X users and makes server access easier as well (although Apple's promised Windows file-sharing support in OS X 10.1 may relegate Extreme Z-IP to OS 9 systems).
Extreme Z-IP runs under Windows NT 4.0 or Windows 2000 Server or Professional (the workstation edition) to provide file and printer sharing via TCP/IP. The program lets Mac users share any Windows directory or-with the optional printer-sharing component, which starts at $675 for ten users-any Windows printer.
Once it's running on a Windows server, Extreme Z-IP lets Mac users see each Windows share as a separate volume in the Chooser or Network Browser. It uses Server Location Protocol to let Mac users choose
from a list of available servers, and it supports long- and encrypted-password authentication.
