NIS is working fine, at least, for what I expect it to do.

What makes you think NIS is involved?
What does yum use NIS for?
Is there a test command I could use to see whether NIS is working for yum?
What names is yum looking up?
Is Errno 12 a clue? I tried searching for (do_ypcall: clnt_call: rpc: timed
out  "errno 12" ), got many confusing hits, nothing obviously helpful.

thanks,
