Directory Entry ussage

I'm cleaning up old directory entries.
These are not objects, so there is no use date on them.

1) Is there a way to tell which directory entries are still needed?

2) What commands or processes require a directory entry?
If memory serves me right, SNDDST, SNDNETSPLF.
If I scan source for SNDDST and/or SNDNETSPLF, I may be able to identify the processes.

3) Would any of the auditing help in identifying these?
If so, which ones?

Any other tips or suggestions would be appreciated.

Thank You
