Fix the Network problem for VMWare (Workstation) in Windows 7 (Semi-functional)

Problem: VMWare’s NAT/Bridged Network is not working in Windows 7
Possible Solution:

• Set Client VM to use Bridge instead of NAT
• In Virtual Network Editor:
  • disable NAT
  • Remove network adaptor for NAT uses.  e.g. vmnet8
  • Change the Subnet setting of VMnet1 (e.g. 192.168.0.0/255.255.255.0)
• Run the patch script below:

Be default, W7 does not allow to run unsigned script due to security issue.
Please un the following command first:

• Run “PowerShell V2” as administrator
• Type “set-executionpolicy unrestricted”
• Leave this PS windows as-is and create the script file “fix-vmnet-adapters.ps1”in your computer:

# *NdisDeviceType  
# 
# The type of the device. The default value is zero, which indicates a standard 
# networking device that connects to a network. 
# 
# Set *NdisDeviceType to NDIS_DEVICE_TYPE_ENDPOINT (1) if this device is an 
# endpoint device and is not a true network interface that connects to a network. 
# For example, you must specify NDIS_DEVICE_TYPE_ENDPOINT for devices such as 
# smart phones that use a networking infrastructure to communicate to the local 
# computer system but do not provide connectivity to an external network.  
# 
# Usage: run in an elevated shell (vista/longhorn) or as adminstrator (xp/2003). 
# 
# PS> .\fix-vmnet-adapters.ps1

    $node = $_.pspath 
    $desc = gp $node -name driverdesc 
    if ($desc -like "*vmware*") { 
        write-host ("Found adapter: {0} " -f $desc.driverdesc) 
        if (confirm) { 
            new-itemproperty $node -name '*NdisDeviceType' -propertytype dword -value 1 
        } 
    } 
} 
popd 
# disable/enable network adapters 
gwmi win32_networkadapter | ? {$_.name -like "*vmware*" } | % { 
    # disable 
    write-host -nonew "Disabling $($_.name) ... "
    $result = $_.Disable() 
    if ($result.ReturnValue -eq -0) { write-host " success." } else { write-host " failed." } 
    # enable 
    write-host -nonew "Enabling $($_.name) ... "
    $result = $_.Enable() 
    if ($result.ReturnValue -eq -0) { write-host " success." } else { write-host " failed." } 
} 

• Back to your PS, change the directory to your script location.
• Type “.\fix-vmnet-adapters.ps1” to run the script
• Anwser [Y] in the prompt for any vmware network adaptors (VMNet08)
• Finally, reset the policy for secuirty reason:
• Type: “ set-executionpolicy allsigned”
  
• Exit the PowerShell
