Hello,
I have question about internet connection sharing in Windows 7.
The problem I need to solve is following:
I have several devices which, when connected to computer, creates new network connection. I want to share my main Ethernet internet connection whenever new device is connected to PC with this device.
I have following code for internet sharing:
Write-Output "Finding RNDIS Network adapters..."
$NICs = Get-WMIObject Win32_NetworkAdapterConfiguration -computername . | where{$_.Description -like "*RNDIS device*"}
if ($NICs) {
$MainAdapters = get-wmiobject win32_networkadapter -computername . | WHERE {$_.Name -LIKE '*Ethernet*' -AND $_.NetConnectionID -LIKE 'Local Area Connection*'}
$RNDISAdapters = get-wmiobject win32_networkadapter -computername . | WHERE {$_.Name -LIKE '*RNDIS*'}
ForEach ($MainAdapter in $MainAdapters) {
$MainAdapterE = $MainAdapter.NetConnectionID
}
ForEach ($RNDISAdapter in $RNDISAdapters) {
$RNDISAdapterE = $RNDISAdapter.NetConnectionID
}
$m = New-Object -ComObject HNetCfg.HNetShare
$c = $m.EnumEveryConnection |? { $m.NetConnectionProps.Invoke($_).Name -eq $MainAdapterE }
$c1 = $m.EnumEveryConnection |? { $m.NetConnectionProps.Invoke($_).Name -eq $RNDISAdapterE }
$config = $m.INetSharingConfigurationForINetConnection.Invoke($c)
$config1 = $m.INetSharingConfigurationForINetConnection.Invoke($c1)
$config.EnableSharing(0)
$config1.EnableSharing(1)
Remove-Variable m
}
The problem is that, when I unplug old device and connect new device, the code does not enable sharing between $MainAdapterE and $RNDISAdapterE. Instead I am getting error in PS:
Exception calling "EnableSharing" with "1" argument(s): "An event was unable to invoke any of the subscribers (Exceptio
n from HRESULT: 0x80040201)"
At C:\path\ethernet.ps1:94 char:25
+ $config1.EnableSharing <<<< (1)
+ CategoryInfo : NotSpecified: (:) [], MethodInvocationException
+ FullyQualifiedErrorId : ComMethodTargetInvocation
I understand that this is somehow tied to the fact that when I unplug old device, without un-sharing the connection, the sharing information is not cleared. This in turn could cause the error, when I try to share connection with newly connected device.
When I disable sharing prior to remove old device with Powershell, then I am able to get the above code to work, when I plug in new device.
Please help me to solve this issue.
