Win2k disconnects mapped samba shares

[Posselt Werner]

Hello,

I stepped through the archives of this list, but could not find a
thread dealing with exactly this problem we are experiencing here.

Server HP-UX 10.20 Samba 2.0.6
security = domain
deadtime = 500    ... that should be enough

The win2k clients map a drive and everything is working fine.
after a period of inactivity (about half an hour) win2k somehow disconnects
the mapped drive
and marks the network connection with a red 'X'.
this is documented as a feature in the win2k knowledge base.
that seems work on nt-servers they reconnect if you access the 'sleeping'
connection.

But it does not work on the samba drives.
it gets reconnected somehow after a few pop-ups telling you the connection
is no longer available and some weird things.

there is a Key in 
\\System\CurrentControlSet\Services\LanmanServer\Parameters
called 
LAN Autodisconnect with a valid range of -1 to 65535
-1 is disable.

But it does not disable this 'feature'
LanmanServer is maybe not really the right place either?

Any idea how to stop this behaviour and keep the connections active?
This would be very much appreciated.

TIA, Werner
