When NACS closed NetBios ports at the border router as a critical security measure, it was no longer possible for campus personnel to use Windows file sharing services between work and home, at least not without working through the campus VPN device. (SeeNACSNews 2002.10)
But there is an alternative for those who need to use a campus Windows computer from home or other remote location which does not depend on NetBios ports.
Windows 2000 Server’s Terminal Services (or “Remote Desktop” for Windows XP) are the recommended means of remotely using and administering Windows systems. It’s free, and secure when configured correctly. Moreover, if you use a Macintosh at home, you can download an ICA client which uses the same technology (based on Citrix Metaframe) to access a Windows system from your Mac.

It is important to note that two recent security flaws were detected in these services for which Microsoft has issued a patch, which resolves the problems. All default installations should be patched prior to use on UCInet. An explanation of the issues and a link to the patch may be found on the Microsoft Web site.
As with all security issues, turning this service on is expected to be safe with the patches installed, but may leave the machine open to manipulation if further vulnerabilities are discovered.
