Vista workstation cannot see some other domain computers

Anyone seen a Vista workstation (Business) suddenly not
see some computers in the domain, yet see others? All of
this clears with a reboot.

Refresh on Network View does not help, nor does diagnose
and repair. I have to reboot.

Yes network discovery is on.

This was not a problem for months until today.
If I allow network mapping on the Vista machine would
that help?

Is there a way around this?

Thanks

Most of these machines were XP, I think I found the
answer:
