Switching wired interface in Server 2008R2

  • 772

I have two 1 Gb wired Ethernet ports on a Dell server. I am trying to move to wired port #1 because of physical damage to wired port #2. The trouble is, 2008R2 won't let me have two interfaces with the same IP address. Ordinarily, I can see this being a good thing - it tries to save you from yourself. However, I am super-paranoid about changing the IP settings on port #1 - is there any way to have the interfaces configured identically so that I can revert the port change by just plugging the cable back into #1? Or, is there a way to save a wired interface config to a file?

It's a critical production server and I can't schedule maintenance on it much, so I didn't want to mess with currently working IP settings if I could help it.

    Use netsh to dump the configuration of the production NIC:

    netsh -c interface dump > path\dump-filename.txt

    Then disable the damaged interface:

    netsh interface set interface interface-name DISABLED

    Then, on the other interface:

    netsh -f path\dump-filename.txt

  2. I really think you are just going to have to schedule maintenance. There's no way to do that without a maintenance window.

    Could you assign another IP to the second interface and use DNS migrate to the other?
