Remote Desktop Wake on Lan

[Twanny]

I have two PCs running Windows XP Pro SP3, networked over a LAN using Cable
and NIC Cards. The Remote Desktop in XP works very well for my needs, except
when I put the secondary PC to "sleep", in which case RDP is unable to
connect again.
Can anyone show me how to "wake up" the other computer over my LAN?
I am a home user with average knowledge about computers but willing to
follow any tips or instructions. Tried to find a solution on the Microsoft
Knowledge base and also did a google search, but all I could find are third
party utilities and am not prepared to purchase software that is used
occassionaly.

Google for "WOL freeware", there are several freeware utilities that will do
the trick. All it does is send a specially formatted packet to the sleeping
machine. Make sure you enable WOL in the NIC properties in Device Manager
and also in the BIOS. On my home setup there is a problem when resuming from
sleep via WOL where the video does not wake up so when you RDP into the
machine, all you get is a blank screen. It was supposed to be fixed in SP3,
but it was not. I also tried installing just the hotfix from the following
article with no luck.

Just saw your post Louis-thanks for taking the time to reply. I will try out
tomorrow
and leave feedback if successful.

Regretably was unsuccessful.
I installed Fusion WOL but once the remote computer is put to sleep, the
utility could not make it wake up. One thing I noticed under Device Manager
(NIC properties, under the Power Mangement tab) that the option "Allow this
device to wake up the computer" is greyed out.
Will keep trying to find a solution.

Did you emnable Wake On LAN in the BIOS? Also, there are sometimes two
places to enable WOL in the NIC properties. You found one of them, (I'm not
sure why it is greyed out.), the other is usually on the "Advanced" tab of
the NIC properties. Perhaps enabling this and clicking OK, along with
enabling it in the BIOS, will ungrey the other option. I seem to remember
having to completely power down and restart, (not reboot), one of my
machines to get the BIOS option to work.

These are the Options I found on the Advanced Tab of the NIC properties:
-----------
1. Link Down Power Saving = Disable
2. Link Speed/Duplex Mode = Auto Negotiation
3. Network Address = Value not present
4. Optimal Performance = Enable
5. Receive Buffer Size = 64K bytes
6. Shutdown Wake-On-Lan = Disabled
7. WakeUp on ARP/PING = Enable
8. WakeUp on Link Change = Enable
9. WakeUp using APM Mode = Enable

Under the BIOS section
Power Management/APM = Enable
Set wake events:
Resume on Ring = Enable
Resume on PME# = Enable
Resume on RTC Alarm = Disabled
ACPI Standby State = S1/POS

For the moment, I cannot find any solution, and though it would have been
very convenient to Wake Up the Remote computer, it's not a critical matter.
Thank you once again Louis, for your time and input.

Change "Shutdown Wake On LAN" to enabled. You might also try changing the
ACPI standby to S3. There are minor differences between these states and all
of my machines are set for S3. Worth a try?

Will do Louis - perhaps we can yet crack this "nut", huh!

No matter what, the Remote Computer refuses to wake up from sleep via RDP. I
have checked all the necessary options and changed BIOS to reflect ACPI S3
mode, to no avail. The fault must lie with the LAN Card ("Allow this device
to wake up the Computer") is still greyed-out. I will either buy a new NIC
card or contact Realtek for their comments.

Thanks for trying to help out.
