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