If you use ShadowProtect or any other backup program to restore your SBS 2008 server to alternate hardware, OR if you have it virtualised and you move it from one virtualisation host to another, then there are a few things you simply MUST do to ensure things work correctly with SBS 2008.
First thing is that upon the first boot, you must use F8 to get into Safe mode. From here disable ANY antivirus software you have running on the system. Some AV software can interfere with the networking stack
Second thing to do is to reboot into Directory Services Restore mode. Here you will fix a static IP the same as the original onto the NIC of the server. Set the Default Gateway and DNS settings as well.
Now reboot into normal mode. Things will come up but you will not have AV protection.
Wait till the SBS console comes up then run the Fix My Network Wizard – it’s on the Network tab and the Connectivity sub tab.
You will likely see the first two items as per below. Allow it to fix those – this may look like it’s paused for a few minutes, but it has not.
Once the wizard has completed you should see the first two items come back to green ticks. Good work.
But wait – you’re not done yet.
The AV services you disabled – re-enable them and do one more reboot to confirm all is good and you are then clean and clear to move on.
