Subject: exhausted all lanman hashes -- error? -- newbie Q

I'm a newbie at using John, however I did follow the tutorials for
downloading the source code, applying the patches, and compiling John
properly. In addition, I successfully retrieved a lost password for an old
laptop, quite quickly at that thanks to the weakness of LANMAN hashes. So I
can follow instructions and get things done...most of the time.

Most recently however, I attempted the same for a very old machine that had
been running windows 2000. I let John run for 22 days before it apparently
exhausted all possible passwords and ended itself. It found "(guest)" as a
password for a guest account...or perhaps I misinterpreted the on-screen
output and the guest account had no password at all. Other than that, it
found no other passwords. My pawdump file included an administrator password
hash that has a LANMAN hash.

Running --test says everything is fine with john. Any ideas of where I
should start investigating or what might have gone wrong? Did I miss a step?
How is this even possible? I thought it would try every possible combination
of characters.
