Today, I was setting up a couple of Dell PowerEdge 1900 servers to use Virtual Server 2005 R2 SP1. All was going well, until I cranked up a guest machine using Virtual Server. I’m running on Windows Server 2003, and had just used the default drivers out of the box, so I figured it would “just work”.
I should have known better! When starting up a guest OS using Virtual Server, the host network stopped functioning altogether! I have two of these servers to set up, so I thought I’d try and replicate it on the other box – funny, it did the same thing. Whenever a guest started that was configured to use the Host NIC, the host network would stop functioning.
After some research, I found that others were having this issue as well, and the issue seemed to point to the NIC itself. After doing a little research, I found a write up by Ray Comvalius that pointed me in the right direction.
I’ve copied and pasted his procedure below:
This is the procedure that worked for me:
Step 1) Ensure the latest drivers from Broadcom are installed on the
host machine (not the DELL ones). These are available from
Step 2) Grab update package from Broadcom that will disable IPMI as
appropriate to your O/S
a) Windows 2003 X64 – ftp://Net_sys_anon@ftp1.broadcom.com/web/utility_x64.zip
b) Windows 2003 – ftp://Net_sys_anon@ftp1.broadcom.com/web/utility_x86.zip
Step 3) Determine the MAC address for the NICs you want to "fix". You
can get this from Start -> Programs -> Accessories -> System Tools ->
System Information : Components : Network : Adapter. There are lots of adapters listed here so be careful to choose the right ones.
Step 4) Extract and execute "run.bat" and enter the MAC address collected in step 3
