SECURING THE TELNET SERVICE & USER GROUPS:

And, a Mr. Markuss Jansson on his point on TELNET service (tlntsrv.exe iirc).

http://www.markusjansson.net/exp.html

Turn Telnet NTLM logings off

-> Run: telnet.exe
--> Type (and press enter): unset ntlm

He also has more on things like "EFS" (encrypting filesystem) which I omitted, & both Mr. J.'s site & the GOVERNMENT ones I note, also cover it too (or, supplement points I made with more alternatives etc.).

P.S.=> I list MORE security techniques for securing telnet, here (did this years ago circa 1997-2002, & it's cited in 2001 here @ Neowin, by searching TELNET on that page) to supplement this technique:

=================================
APK "A to Z" Internet Speedup & Security Text!
=================================

http://www.neowin.net/news/main/01/1...-security-text

=================================

Which goes into that point on TELNET & many others (including more speed tuneups, services cutoffs for speed + security in DETAIL & far more also to supplement this post here)... apk
