My origional question -

Who pointed out that the patches replace the origional and
rename it as

However, my first question still remains un-answered. I'd be grateful to
anyone who can extend a helping hand. For now, I have modified the
/etc/resolv.conf file on all the client machines to use dns along with nis
for name resolution, but THIS IS NOT WHAT I WANT!!!
