How to enable/disable network adapter in VB.

[BOOGIEMAN]

Hello guys/gals!

I'm working an a small scheduling utility for my boss to use on our WinServer. While I'm at it I realized I could add an extra feature to it that I think he would appriciate. He has been Indecisive about weather to shut the server off at night or not. He doesn't like the idea of shutting the server down every night but he also doesn't want to leave it running after work hours with internet vulnerability.

Simple solution: I could schedule the network adapter to be disabled at 6pm and re-enabled again at 6am or something. That would be perfect!

I'm sure theirs an API function to do that but I don't know it. I've surfed the web a bit for it but it seems like a close guarded secret (I guess to minimize the threat of sabotage or something). And I understand. But I still need to know.

Could someone at least point me in the right direction please?
If you don't want to post that on this forum PM me.

Still waiting....

Please!?

I'm kind of at a stand still here.

I don't know how to disable a network adapter from VB; if I had to do it, I would start by investigating WMI.

You might also look into the various Windows firewall products (e.g., ZoneAlarm). I believe some of them allow you to close network access at scheduled times.

Okay, thank you.

Hi,

Without having any experience about them, try the functionality of

WNetCancelConnection()
WNetAddConnection()

Yea... I'm still stuck on this one. I'll look into those functions and see if they're work. Thanks Bernie.

Currently I'm doing a search on registry edits. Is there a registry setting that can enable/disable and network adapters? That may be a good way to do it.

To help finding the right registry entries you could download 'Registry Monitor' from http://www.sysinternals.com
That tool monitors the events in the registry so you can keep track of what happens there when you enable/disable the network driver the ordinary way.

Similar tools are also availible for monitoring files and ports.
