Re: setting IP address without using control panel

Thanks for the suggestion. While I did not call this object/method from my C
application, I tried a VBS script I downloaded from MS. I thought the less I
had running on the machine of my code the better to isolate the issue. This
is the script I pulled down:

strComputer = "."
Set objWMIService = GetObject( _
"winmgmts:\\" & strComputer & "\root\cimv2")
Set colNetAdapters = objWMIService.ExecQuery _
("Select * from Win32_NetworkAdapterConfiguration " _
& "where IPEnabled=TRUE")
strIPAddress = Array("010.000.000.001")
strSubnetMask = Array("255.255.255.0")
strGateway = Array("000.000.000.000")
strGatewayMetric = Array(1)

For Each objNetAdapter in colNetAdapters
errEnable = objNetAdapter.EnableStatic( _
strIPAddress, strSubnetMask)
errGateways = objNetAdapter.SetGateways(_
strGateway, strGatewaymetric)
Next

As I said it appeared to work beautifully until I rebooted the machine.
Then IPCONFIG reported I had no adapter at all, though it showed up exactly
as one would expect in the netowork control panel applet. To get it to "show
up" at the cmd line and start operating again I had to use NCPA to switch
back to DHCP. At this point, the IPCONFIG still returned nothing. I then
right clicked the connection icon and said "disable" then "enable" and
everything was back to normal. If I hadn't already tried this on 2 different
machines with 2 different NICs I would suspect a crumby Realtek driver
implementation. Do you have any other thoughts?
