True, but if Internet Explorer (or Exploder as some say :-)) is provided
free with every Win 95 and Win NT box, why would I consider anything else
for a PC network?  Also, I haven't used Netcape Communicator - does that
support NTCR?

Sort of.  You can set up a one-way trust relationship with the MSP server,
so it doesn't store account information for the user (a possible security
risk if the server is compromised).

Another security risk again, and one that I don't really have an answer for,
apart from telling users NOT to use their LAN usernames and passwords when
setting up accounts on remote sites - but how do you enforce this?
