No you won't, because both you and your cow-orker are smoking entirely
too much crack. (Him for hallucinating this problem in the first place,
and you for believing him enough to post this query here.)

Do rpcinfo -p on a FreeBSD host running NFS, NIS, AMD, or whatever,
and you'll see both UDP and TCP entries for each service. If it didn't
work, somebody would have screamed bloody murder about it long before
now.

You don't explain how your cow-orker is trying to register these
services (it's probably a custom RPC application, but he could be using
a hammer and chisel for all we know), nor do you go into any detail
at all about what "doesn't work" means. The correct procedure here
is to take away his crack pipe and pump him for more details, *then*
post here only after you're sure he's not imagining things.
