Cannot rename this connection. A connection with the name you specified already exist. Specify a different name.

If you are trying to rename the existing NIC and receiving above warning on VMWare host fallow the easy steps to fix the problem, hidden NIC card in the device manager is causing issues….

1.Click Start, click Run, type cmd.exe, and then press ENTER.
2.Type set devmgr_show_nonpresent_devices=1, and then press ENTER.
3.Type Start DEVMGMT.MSC, and then press ENTER.
4.Click View, and then click Show Hidden Devices.
5.Expand the Network Adapters tree.
6.Right-click the dimmed network adapter, and then click Uninstall

Thanks for the concise resolution. Anyone know the reason for this behaviour?
Our automated server builds are not renaming the nics because of this.

Excellent tip, but if you are doing this on a Windows 2008 R2 server, remember to open your console (cmd.exe) up with Admin rights. (Hold down the shift key and right click on the Command Prompt icon. Otherwise, you won't see the hidden devices.

thanks ... this is NOT WORKING ! :)

but I FIX IT:

you do NOT press start then type devmgmt.msc, you type devmgmt.msc in the exact same cmd window where you set that variable (so device manager will have variable set), THEN IT IS WORKING :P

thanks anyway :P
