Enablestatic function fails with errorcode 84   

Hi,

I am facing this problem of setting the IP address on the Public Ethernet 
adapter(of Intel Series). The OS is Windows 2003 server SP2. The EnableStatic 
function fails with return code 84. I tried a lot to figure out the problem 
but in vain.

Any help in this regard will be highly appreciated!!

c#- WMI - EnableStatic fails with error code 84 -"IP not enabled"   

I need to be able to configure the adapter  when it  is not connected to any device.(has no link light on it)  I am using following method(WMI-enableStatic)  to assign static IPaddress to selected NIC. 

It works on XP  but returns an error code “ 84 – IP not enabled” on Vista OS. 

I have a peer-peer connection with device.  The following call works on Vista as well if device is powered on (I have link light on NIC) . Is there a way I can assign adapter a static IP address that it can use at later time when device is up and running ?

Any help/ pointer will be appriciated.
Thanks in advance,

            ManagementObjectCollection objMOC = query.Get();

            int ManagementObjectCount = 0;
            foreach (ManagementObject objMO in objMOC)

                    if (string.Compare(macAddr, macID) == 0)

                        objSetIP = objMO.InvokeMethod("EnableStatic", objNewIP, null);
                    }
                }
                catch (Exception ex)
                {
                    log.InfoFormat("SetIPAdress failed  to set IP : " + ex.Message);

                }

            }
        }
