It is my opinion that the messenger service should be disabled as standard hardening of workstations. There is nothing that prevents a "rogue" computer from sending another computer a few hundred messages causing a semi-denial of service. This is especially the case is public (campus) networks where end users are random. Many services can take advantage of the messenger services, Compaq/HP Insight manager, Most A/V Software, Backup Software, you name it. But I can think of no software that relies on it implicitly to be able to run. Eric C. McCarty Systems Administrator Internet Security Officer -----Original Message----- From: Nestor L.

I've disabled Messenger service on all my nodes (Windows 2000 network with XP clients) and have experienced no problems whatsoever. In addition, I also run BackupExec 8.6 from Veritas. Now, if you have any software configured to send an alert via the net send then you will have problems. Otherwise, in my experience I have not had any problems.
lo all, I would like to compile a list of software which relies on the Messenger Service for inter process communication. I believe some backup software packages due but i'm not

complain? Thanks a lot for your input and if I get enough I will post a list of the packages on my site sh0dan.org. Thank you, -wire -- Visit Things From Another World for the best comics, movies, toys, collectibles and more. http://www.tfaw.com/?qt=wmf
