Missing network adapters

I have two, onboard NICs, Intel 82575s.  Device Manager shows Connection #3 and Connection #4.  It does not show the original devices, which are Connection #1 and Connection #2.  The present 3 and 4 "replaced" 1 and 2 and work fine, but really haven't replaced 1 and 2.  For example, I cannot rename 3 or 4.  I want to remove 3 and 4 so that 1 and 2 reappear.  I tried uninstalling the NICs 3 and 4, but they came back on reboot.  I attached a screen shot from Device Manager.

In Device Manager, go to View, and click on Show Hidden Devices.  Adapters 1 & 2 may show up but as disabled or missing.  Try deleting them.  That may cause 3 & 4 to change to 1 & 2, or you may be able to rename them after the phantom 1 & 2 have gone away.

Did you disable 1 and 2 in the systems BIOS? Once you have disabled in BIOS when you boot those should be gone. Once you have done that uninstall other network card then on reboot they should show 1 and 2.

This is common when you have a PCI card in the system

The only option in the BIOS is to disable the NIC ROM.  Doing so did not resolve the issue.

>This is common when you have a PCI card in the system

Perhaps, but this issue presents on only one of several systems with the same config

Hmm. So, in the BIOS you don't have the option to disable the on board network card? Have you fully remove the new card out. disabled the other on board network cards? Do these on aboard network ports show in Device Manager still?

No, there is no option to disable the NICs.  There is no other network card in the system.  There is a video card (PCIe), 1394(b) card (PCI-32), and RAID controller (PCIe).

Alright maybe I read your post wrong. You aren't adding network cards you just have an with built-in network ports showing as 3 and 4, right?

Yes.  There are only two onboard NICs.  At one time, they showed up properly as 1 and 2.  Now, they're 3 and 4.

Alright sorry I was confused then. Did you make any changes?

I see you have VM virtual adapters listed. How many physical network ports do you have on the server?

Do the other servers with same config have VMware installed? I'm wondering if these other VMWare adapters are causing the problem

Doesn't make sense. No changes to the system?

Can you remove VMWare adapters to see if that does anything?

The only other thing I can think of going through http://support.microsoft.com/kb/269155

I've seen this many times, can happen via removing and reinstalling the NIC drivers, or updating the drivers.  Let me take a look at our servers...

Fixed!  I followed Method 1 in the link that you provided.  Then, the phantom NICs appeared in Device Manager.  I removed them and I removed the valis ones, too.  After reboot, only 1 and two appear.  Thanks!

I'd forgotten that just clicking on Show Hidden Devices in Device Manager may not be adequate...
