Hyper-v Virtual Machine- Ethernet port versus Network Adapter

Hi Experts,
I created few virtual machine on my Hyper-v environment . when I was looking at the network adapter on one of my virtual machine I realized that the speed was 100M while all the other shows 10Gb, then when I looked a the name it shows Intel adapter while all the other one shows Microsoft virtual.
so I turned the virtual machine off and realized under settings for this VM I see "Ethernet Port virtual switch" while others shows "Network Adapter virtual switch"

my questions are:
1-what is the difference between the ethernet port and network adapter
2-how did I create this ethernet port since I am trying to recreate the steps but can't figure out where and how to add this hardware to my VM
3- of course the VM that has this issue is one of my DC , so if I remove the ethernet port and add the network adapter instead and reconfigure the ip on the adapter would I create any other issues? this VM is a DC-DNS-DHCP-

Thank you for your help.

I don't remember seeing those terms... can you post a screen shot?

There are two types of NICs you can use - Legacy and Synthetic.  The Synthetic is MUCH, MUCH faster (it claims to be connected at 10Gb) but requires integration services on the guest.  I THINK the Legacy is 1Gbit (COULD be 100 Mbit, don't remember).  It emulates a NIC (forgot the chipset off hand) and allows guests without integration services to have a network interface (the latter is generally used in OLD Windows installs (2000 VMs for example, or linux VMs) and the former is typically used on anything 2003 R2 or later in the Windows world.

you are right I saw on top of the screen showing legacy; but I am not sure how I did set it up. I actually took the initiative to remove it and install another network card.
Everything seems to work fine, and now I have 10GB but do I need to update anything in my server since it has a different mac address? do any services running on a DC looking at the mac address instead of just the IP address?
Thanks

Honestly, I cannot find any reference to what "Ethernet Port" is referring to in the VM config... I thought it might have something to do with VLANs, but no.  Did you import the VM from Virtual Server?  Can you post the VM's config file (it should be an XML file).

Making Bulk Changes to Active Directory

Watch this video to see how easy it is to make mass changes to Active Directory from an external text file without using complicated scripts.

I removed the Ethernet port and only left the network one. Would it still show in the configuration file the removed port? When you setup a legacy network how does it show in the vm setting page?

Lee W, MVPTechnology and Business Process AdvisorCommented:
It would say you have Network Adapter or Legacy Network Adapter with the Virtual Switch either is connected to.

(Easy to test, create a VM (don't bother installing an OS or even turning it on) and add both).

Well, I just created a VM and added the 2 types of network adapter and they show like their name states. I really can't see where I would have added this ethernet Port.

You didn't import the VM from Virtual Server or something else?

No it was a new VM . The only way I could have created a VM is thru :
Hyper-V Manager, or my failover cluster manager services and applications or System Center Essential 2010.
Pretty weird

remove the switch and add a network adapter and set it to use your Ethernet adapter

I don't see this in hyper-v at all.. are you using server 2008R2 or 2012?
This is what I see
