The implication is that you need to repeat my discovery. Connect another
computer on the wire and subnet that causes the boot to fail. Now, boot the
Server and then, using the ARP cache you can pull on the second computer,
determine if there's another device on the subnet that is attempting to
block that IP from being used. In my case, it was a subnet that was part of
an entire building....way to much to do a trial an error test. In your
case, I suspect that if you simply disconnect or substitute the
switch/router or just power them off instead of unplugging the SBS cable,
you will be able to determine which device is causing your problem. From
there, dig into why your SBS is being denied an IP.
In addition, when I inspected the Event Log, I saw an error indicating that
the IP was already in use during the boot sequence.
To repair this problem, you will need to know what the cause is, but
identifying the device causing it is the first step.
