There's something fishy here. As this is a server then one would guess 
that it would be configured with at least one static IP address and for 
the hostname to resolve to one of those addresses. From the mails it 
sounds like the hostname is resolving to a list that includes an APIPA 
address address, which suggests to me a Windows bug or else 
configuration that causes the APIPA to be automatically registered. Do 
you have a reference to the patch that is causing this, it would be nice 
to read the description. Also Microsoft tend to add registry settings to 
revert behavior changes and maybe there is something for this. As I said 
in one of the earlier mails, the patch is fine and seems completely 
benign, it's just that this thread lacks the meat to completely explain 
why it is needed.
