VNC disconnects every couple minutes!!!!! XP--->2003

[Thomas G. Marshall]

Your basic "HELP ME!" here.

My wife is *trying* to work at home and has bumped into a showstopper of a
problem. For some reason (and we don't know why) sometime around 2 weeks
ago she discovered that her VNC connections into work just don't hold up.

They seem to be breaking connection every couple of minutes. Sometimes
it'll last an hour, sometimes a minute.

We're on Verizon DSL, and while that sure does have its own issues, it
certainly wouldn't be this bad. (768/128).

The VNC site said something about a known incompatibility with fast user
switching, but that can't be entirely true since she was using this fine for
months. There is a detail not being established here somewhere.

Please, if you can:

1. Tell me your thoughts on this

and/or

2. If you have the time, help me to diagnose this further to describe this
most accurately. I'm a software engineer for 20+ years, but just have never
had to diagnose network problems before. I've coded at the TCP/UDP level,
but never had to "fix" other apps outside my direct control.

Someone on the verizon site said something about the MTU possibly being too
large. I was wondering if this makes any sense on your end? Message
Transfer Unit?

Thanks!

Thomas,

The following web site should give you an overview of MTU or maximum
transmission unit concepts:
http://www.cisco.com/warp/public/794/router_mtu.html

If you have a home network this setting can be changed on the router. Hope
this helps.

Kind Regards,

Under intense debriefing my wife just admitted to *read* error message
when this occurs.

read: Connection reset by peer (10054)

Does this help anyone?

Usually means that the high-speed connection is down (home or work
connections). Usually ISP need time to replace/repair and maintain their
hardeware. Also, without having a T1 line connection, no high speed
Internet connection is guarrantied to be running correctly 24/8/365.

That makes no sense. My connection is NOT down! The problem is a
disconnection every couple of minutes, for about 2 weeks now.

It's verizon dsl, it's up, is fine, has no other connection trouble. Her
work is up and is fine, and no one is reporting problems.

It's the pesky read error from vnc.

You can use TCP Optimizer available here
http://www.speedguide.net/downloads.php to optimize MTU etc.
