Wake up remote computer via RDC when on VPN

[janezcas]

Hello,

I have configured my computer at work to go to standby after 30
minutes (S3 standby). I have turned on Wake up on LAN option in BIOS
and checked the following two options in network card properties in
Windows XP:
- Allow this device to bring the computer out of the standby.
- Only allow management stations to bring the computer out of the
standby.

Now if I try to wake up the machine when in standby I have to send the
magic packet and this works fine. After I send the magic packet from
another computer on LAN, the computer wakes up from the standby and it
is possible to connect remotely via Remote desktop connection.

Now I wanted to use this when working at home via VPN. What I have
found is the following:
- If I put the computer at work in standby manually via Sleep button,
I can connect remotely to it via VPN. I just have to send the magic
packet and connect via RDC (the procedure is the same as when working
from another computer on LAN).
- If the computer goes to standby automatically after 30 minutes, the
magic packet does not wake it up?!

What could be the difference between manual and automatic standby
regarding wake up?

The problem is only present when working via VPN. When working on
another computer on LAN at work, the magic packet wakes up the
computer from standby no matter how it went to standby (manually or
automatically).

All computers involved are running Microsoft Windows XP Professional
SP3.

Thanks
Janez

I have a similar problem but from within the office, If I switch off my PC
it can wake up on LAN without problems. BUT if I put it on standby or
hibernate, it won't wake up on LAN at all.

Can anyone send me any ideas about what could be going on?
Thanks

Make sure that the LAN card is not configured to be put to sleep
to save power.
