Dunno
Current system: MicroVAX in each field office. Users log on locally via Reflections.
New system: Everyone access the single DEC in the server room via thin clients with web access in the field offices.
Due to flaky communication, we don't want to use telnet from the field offices. One solution is to run the telnet session in the server room, then connect to that session somehow via internet on the thin client.
Current thinking is Terminal Services and Java apps are "too thick". (Not my description, or my thinking.) Suspicion (again not mine) is that anything based on sending bitmaps -- ala VNC -- will be equally slow. I'm convinced someone has figured out how to separate the textual display of the terminal from the telnet session.
Or are we inventing our own problem here? Is it true that an intermittent connection will keep dropping telnet sessions?

telnet is of itself not connection oriented
it is a stream of packets carrying one character at a time. What usually horks the telnet session is a timeout, where the server determines the next character isnt coming soon and hangs up. Telnet accross the net isnt that secure anyway so best practise is to establish connectivity with your Dec server then connect to the othrs from there. Even better a ssh enabled terminal server to connect to from the outside. SSL perhaps instead so people could use a "browser" look and feel. Something like this

It's a TCP protocol, so *is* connection-oriented

For one thing...
Don't use Telnet.
And yes, putty does telnet better than most. It also does SSH. Not I know both personally and indirectly that openSSH runs on VMS. There ar a few tricks, but it is very doable.
You might just want to mention that Telnet is plain text. SSH is a much better solution, best of all most SSH Clients can manage to hang onto a connection much better than telnet (including Putty)

Where does Reflections come in?
That's what they currently use. Am I mixing up the terminology to say that they're using telnet?

Reflection is a terminal emulator...
...and one of the protocols it supports is Telnet.

DING...DING...DING!
Some companies use a Suite of things when they only need a Terminal Emulator.
Reflections is a suite, of which one of the protocols it supports is telnet.
Cost is mucho too much for just an emulator.
Drew:
Try Putty and see if it works and turn on the keepalives. They could do that now and still keep Reflections.

Looks like putty connects
Time to go track down someone who knows the old system and can try it out.

PuTTY and SSH
Coupla points, mostly in a "what you said" stylee.
Firstly, PuTTY is excellent at hanging onto a connection, as long as you turn on the keepalives. It has a habit of letting connections time out if you don't.
Secondly, yes, SSH does run on VMS, but unless Droo's people have got a software subscription, those MicroVAXen are likely to be running something reasonably ancient (i.e. VMS 6.x or even earlier), and SSH is only supported on VMS 7.3 onward.
It works teh roxxor.
