WMI query returning IP address of VPN adapter, not physical NIC

Hi all,

I'm posting here in hopes that someone can make a suggestion that I can pass along to one of our application vendors.  The vendor's application is using WMI to query the IP address of the PCs it manages.  Some of the PCs in question have a Juniper SSL VPN client on them that is used to connect with a customer site.  When the users of these PCs establish the VPN session, WMI starts reporting that the IP address is the one used by the VPN adapter, and not the physical LAN connection.

Clients being queried are all Windows 7 Enterprise.

The vendor is not making any progress on this.  Does anyone know of a way to prevent the IP address of the VPN adapter from becoming the one reported by WMI?  Attacking from a different angle, is there a more specific WMI query they could be making to get the right info, recognizing that this revised query would need to work in many differing environments?

Thanks,

Steve

I don't think that there is any way to prevent the VPN adapter from being seen in the WMI query.  It would probably be easier to figure out how they are doing the WMI query for adapters.

Assuming there is one query one might do to get this information, can you confirm that it returns a list of all IP addresses?  Are there multiple queries one could pose to return IP address information, and how are they different?

We are talking to the vendor about how they handle the output of the query - as you said, that may be our best option.

Thanks

I would think that they are using Win32_NetworkAdapterConfiguration class...

Win32_NetworkAdapterConfiguration Class

There are a few properties for each adapter, that might give them a clue as to what type of network adapter, and avoid any VPN adapters...

Yes, seems like there are a few options in there for picking the right adapter.  Thanks!
