JSI Tip 8270. How do I retrieve an interface {GUID}?

In order to be able to accommodate multiple network adapters, many networking settings are located in the registry under an interface {GUID} (Globally Unique IDentifier), such as:

HKEY_LOCAL_MACHINESYSTEMCurrentControlSetServicesNetBTParametersInterfacesTcpip_{GUID}HKEY_LOCAL_MACHINESYSTEMCurrentControlSetServicesPSchedParametersAdapters\{GUID}HKEY_LOCAL_MACHINESYSTEMCurrentControlSetServicesTcpipParametersAdapters\{GUID}HKEY_LOCAL_MACHINESYSTEMCurrentControlSetServicesTcpipParametersDNSRegisteredAdapters\{GUID}HKEY_LOCAL_MACHINESYSTEMCurrentControlSetServices\{GUID}ParametersTcpip.

I have scripted InterfaceGUID.bat to retrieve the {GUID} based upon a connection name that you specify, such as Local Area Connection.

The syntax for using InterfaceGUID.bat is:

Call InterfaceGUID Name GUID

Where Name is the connection name, and GUID is a call directed environment variable that will contain the {GUID}, or none if the connection name cannot be found.

NOTE: InterfaceGUID.bat uses REG.EXE built into Windows XP, Windows Server 2003, and newer, or from the Windows 2000 Support Tools.

InterfaceGUID.bat contains:
