Phantom Adapter on a 2008R2 VM (running on ESXi 4.1)

I removed an adapter from a VM and it is still showing up in that VMs 'ipconfig' results.  It isn't 'physically' there in terms of the VMware host, it isn't in the device manager of the VM or in the network connections window, only the 'ipconfig' results.  When I run the BPA tool for Exch2010 it sees this interface as a problem since it is getting DHCP on a 169 network.

Anyone know how to get rid of such a phantom device?

have you checked hidden devices?

see here for details


then check if you've got a hidden network card you can remove
169.254 addresses ar known as link-local it will be a network adapter like a terado tunneling psuedo-interface or an isatap

see http://en.wikipedia.org/wiki/Link-local_address

Sure enough the link hanccoka posted showed a greyed-out VMXNET3 adapter in the device manager.  I "uninstalled" it but it is still showing up in IPCONFIG.

Has Powershell sent you back into the Stone Age?

If managing Active Directory using Windows Powershell® is making you feel like you stepped back in time, you are not alone.  For nearly 20 years, AD admins around the world have used one tool for day-to-day AD management: Hyena. Discover why.

Going to do a reboot and if that doesn't work, uninstall reinstall VMTools.  

I'll post if that fixes it 2nite.

in ipconfig /all what type does it say the Network Interface card is?

what's the description of it?
ChocolateRainAuthor Commented:
This is what my "ipconfig" looks like.  noticed that it calls it a Microsoft Failover Cluster Adapter.  


Might not be related to VMware at all, although its good I cleared up that hidden VMXNET3 adapter anyway.

What are the server application installed on this machine?
Microsoft failover cluster virtual adapter installs only if u have exchange on it,pls check & confirm

okay, if it's the Microsoft Cluster adaptor, leave well alone. It's normal to have it.

see this link if you want to know what it's for
