VPN Client Hangs When I Sleep/Resume My Win 2k Dell Latitude D400

Does anyone know why my VPN client often (but not always...) screws up
when I sleep/resume my Win 2k Dell Latitude D400 working via a home
wireless router and NTL Broadband? Doesn't seem to matter whether I
disconnect first then sleep, or sleep while connected, when I resume
and try to reconnect it often hangs before it completes the
registration. Only solution is to reboot.

It depends on what your sleep is set to.. There are usually settings for
screen saver/hibernate/shut off hard disks... I run off AC and have the
screen saver set to 30 minute, but the hibernate/shut off the hard disks set
to never. Since it's a notebook, if I want to close the lid, it shuts down
anyway (but then it may or may not restart).. Now I just do a shut down,
rather than close the lid.

If I hibernate while VPN is connected, I have to reboot.
If I disconnect VPN before I hibernate, I only have to reconnect.
If I suspend while VPN is connected, I only have to reconnect.

This is Nortel VPN and WindowsXP-SP2.
If you added the wireless, or a new adapter card after you installed VPN,
you might want to uninstall VPN and install it again.
It's supposed to bind to new NICs, but I don't think Nortel does very well.

i think it depends on the VPN, settings and how long you suspend for.

i use Cisco VPN clinet into a VPN 3000 server @ work - a quick suspend is
sometimes OK, but usually the link stops working.

i suspect there has to be some background traffic - or the VPN server throws
away the association to the client.

if will reliably reconnect though - but it takes a while to detect a broken
link. you can speed it up by manually dropping the old link and signing on
again.

Thanks for the thoughts. I've now changed all my advanced power
settings to Standby rather than Hibernate, and when I resume I can
reconnect to VPN fine. Still don't understand why the difference, but
at least it's sorted (as long as I don't leave the machine in Standby
on battery until the battery gets low enough for it to Hibernate
automatically I assume).

Yup, the big offender is usually the hard disk. When it goes into hibernate
rather than standby, it actually turns off, and has to spin back up to
speed.
If you run off AC power plugged in rather than battery, you can just say
hard disk shutdown (on AC never, on Battery xx mins), then you never have to
worry about it dying on battery.

That's about the only time I get "caught". I do have power saver settings
for battery to sleep and then hibernate. I guess I catch it before the
hibernate. I only have to reboot after a low power hibernate.
