How do you get rid of an old server name in your list?

Hey all,

My notes client has an old server name in it somewhere, but I can't figure
out where or how to get rid of it.

For instance, if you do a 'file/database/open', the first server listed in
the box is Local.  The second is the old and invalid server name, the next
two are the good ones.

No one I've spoken to still has this old server name anymore.

Most of the time, this doesn't cause problems, but there are a couple
domino applications that do a NAB lookup, and it says 'can't find path to
server', although in other apps, i have no problem doing a NAB lookup.

any ideas?

Thanks,

Rick
