I can ping the solaris 10 server but can't ftp or telnet to it

I am having a problem to ftp and telnet to Solaris 10 server; from remote machine.

I was able to ftp to this server before, now I can only ping but can't ftp or telnet to this machine. I ran inetadm -e ftp command and tried svcadm enable /network/ftp but that did not resolve the problem.
