RAS AutoDisconnect Timeout/Outlook Client

I've had problems - in the form of users complaining of dropped RAS connections.  I've seen it myself once or twice.    I suspect something aside from the normal 'phone line conditions' excuse in this case, due to frequency primarily.  Our setup is NT4.0/sp3 on a Dell PowerEdge 4200, 4 Port internal DigiBoard attached to 4 USR Sportster 33.6k's.  

RAS has a 'AutoDisconnect' default setting of 20 minutes, apparently paying attention to only 'NetBIOS Datagram Applications', according to the documentation that details where to modify the registry value for this setting.  <erk - editing the registry for idle timeouts - what the ?!@$#>

Anyhow, I've seen more than one connection drop while actually transferring data from an Outlook '97 client to our Exchange 5.0 server.  

My Question is this:  What does Outlook send, when transferring email and attachment data, and does it count as 'NetBIOS application traffic'?  -- I know what NetBios is, but I've heard through the rumour mill that Outlook communicates primarily with RPC's, which I doubt are 'really' NetBIOS traffic - any info would be greatly appreciated -- hopefully before these users scalp me.

<grin> -- Thanks,

Scott.  

PS - As Always, points'll increase as this gets uglier.

If you want to circumvent the problem, set up a scheduled command to run every 15 minutes. Have it run nbtstat -A \\server and make the job non interactive. This will ensure you have some kind of netbios traffic running during the connection. Of course this will have the effect of not ever having a connection timeout, so you may as well drop the 20 minute autodisconnect.

Thanks for the workaround.  Turns out that my problem was with a mangled RAS setup on the workstation.  Some wierdo problem where the entire IP stack would shutdown almost randomly.

Cheers,
Scott
