[OpenAFS] 1.7.3 Windows 7 client explorer window delay

[John W. Sopko Jr.]

I have been out of town, thus the reply delay. I had openafs 1.5.x installed, 
my lmhosts file looks like this:

10.254.254.253	AFS	#PRE

Note I had removed the loopback interface in Device Manger after I did
the upgrade to 1.7.3 . Also I have 2 additional 10.x.x.x IP aliases on the 
interface that I use to manage various devices. I get no timeout in other
network shares.

When we get a chance we will try another machine with a single IP address.
