RAS AutoDisconnect Timeout/Outlook Client
Posted on 1998-11-18
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,
PS - As Always, points'll increase as this gets uglier.
