question on access to res utility

[Joanne McClintock]

I'm helping a new writer use tech pubs lab routers. In trying to use the res utility, he gets the following:

-bash-2.05b$ res show tp5
-bash: res: command not found

In giving the uname -a command he gets:

-bash-2.05b$ uname -a
FreeBSD bigpink.juniper.net 4.10-RELEASE-p2 FreeBSD 4.10-RELEASE-p2 #0: Mon Oct 25 16:23:23 PDT 2004     root at bigpink.juniper.net:/usr/src/sys/compile/bigpink  i386

We are wondering if perhaps this is an access problem. Any ideas? Need any other information? Thanks.
