I'm trying to find a way to enable a network interface with C++.

After trying various methods, I ended up looking at WMI. I found a
Win32_NetworkAdapter class that had an Enable/Disable function, which looked
perfect for what I needed. Unfortunately, the Enable function was only
supported in Vista. Is there another class in XP that I can use to Enable an
interface.

thanx, mark

Did you try SetIfEntry() before you turn to WMI ? Just a hint

The IP Helper functions typically use an interface index. Depending on what
I’m doing, I use various methods to get this interface index. Typically I
use GetAdaptersInfo or GetAdaptersAddresses. Interfaces that are disabled
are not returned via these calls. So I was unable to try to enable a
disabled interface.

However, to see if the call worked, I tried to disable an enabled
interface. By setting dwAdminStatus field via the SetIfEntry. I was
expecting to see the “status� in the RMB on My Network Places->Properties
show disabled. This did not happen, but the interface was “down� or not
usable… ( I could not ping or access anything on the network) So the call
did something, but I’m not sure exactly what. Just what is the dwAdminStatus
field? Is there a different field that I should have set?

thanx for your response, mark

No, look at the description in MSDN or set to MIB_IF_ADMIN_STATUS_DOWN or
MIB_IF_ADMIN_STATUS_UP
and check return code. You need to check index when NIC enabled because
system return the same index for adapter when it's on
