XP Network Problem

I think it might have to do with your NIC. Alot of the new NICs have the option to 'go to sleep'.

Check the documentation that came with your NIC or search on their site to see how to prevent it from going into sleep mode.

It could also be your monitor/lcd that is going to sleep.

Check your bios settings and make sure that everything in the bios as far as power management, is as you want it. In fact, if this is a desktop computer, then I recommend that you turn off all power mangement in the bios.

In Windows, make sure hibernation does not take place when the unit is powered (ie operating from a wall/electrical situation -- versus a laptop/battery situation). And set the other power mangement options (Control Panel --> Power) as you want them to be.

Well... I believe... =)

In XP there is a "normal"-sleep and a "hibernation"-sleep. If it's normal sleep the screen just goes blank. If we are talking hibernation, it writes a memory-dump to the harddrive ("C:\hiberfil.sys" I think) and then it shuts down. This file is exactly the size of your RAM for that reason. This feature's intended "audience" is those with a portable-computer.

Now I don't know "how deep" it's been sleeping, and how your BIOS is set up. Some BIOS's allow you to bootupat a keystroke, actually more confusing than good is, if you ask me. But I can tell you where this hibernation is turned on and off.

1) Right click on the desktop, and choose Properties, select the screen-saver, and choose the power-management.
2) Now there on screen there should be combobox where you can change "system-standby" options. Select "Never" and shut down the computer manually.

3) This is more a foot-note, but I think you should know this as well. There also should be a pagecalled "Hibernation" or something similar.

Now in the checkbox you can enable/disable as you wish... I only know this because I use it to free up 0,5 GB on my system-drive. =)

Hope that helped, or maybe post again

I believe this is by design. in an attempt to make XP more secure, once your machine has been left "unattended" it "locks" down. disconnecting from the network. Whenever i relog into my xp machine i notice the network popup bubble stating "lan connection established"
never bothered to investigate how to turn it off..so this is more of a piece of mind than an answer but i will check into a way to stop it.
