network adapter already exists Intel 1000

Hi Experts,
starnge things I have discovered on some vm's.
I work with vsphere 4.1 on esxi 4.1.
In the beginning I had all network adapters set to flexible. But we want to use vmxnet3 for the network adapters, so I changed all of them.
First I deleted the adpaters and added the new ones.
But now I always have this error: see the picture.

Yeah...standard error with vmnics. Basically, what you should do is change your orig NIC to DHCP, then remove the Adapter from the VM. When you add the new Adapter type and enter the IP, you shouldn't receive that error.

what do you mean with the original nic ?

Sorry...the NIC that was orig configured in the VM (before you remove it to receive the VMXNET 3).

This can happen, it simply means that the VM Nic has not directly replaced the physical NIC, which is still in the registry.

If the the above method suggested by coolsport00 does not work try the below, this is what I do then I see the error.

Search through regedit for the server IP address. Under HKLM\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters\Interfaces - there will be a number of IDs listed of which two will have the server IP address. Determine which is the old adapter (possibly has different DNS/WINS settings or a specific NIC name) and delete the key with the old NIC details. Take care with this edit!!!!

Hope this helps.
