When I telnet from a PC I have to wait ~30 seconds to connect. Upon connecting, the command RCP also does not work but running other applications seems OK.

is the telnet to a host in the same segment ?

if not, probably its a routing problem. ping to the host
from the PC, check if its a network problem (takes long) or
a routing problem (low TTL).

in the host, try to use "traceroute" to the computer you try to RCP to/from and look if the routing order makes scence.

anyway, to fix the problem if its a routing problem, you just have to configure the routing tables correctly.

If the remote machine is using NIS, NIS+ or any other naming service (or combination of them) then the time to stablish the initial connection could be relatively long. One way to deal with this is to inlcude as much as possible in local files, but this defeats the porpouse of a naming service.

 rcp is controlled by .rhosts in the home directory of the login account you use in the UNIX machine. Check the man page and compare that with whatever you have there. If there is not such a file you don't have permission... check also the man page for hosts.equiv, it is a similar thing but for all the machine's users.
