what to do when you are stuck

hey everyone...i am new here and i thought if i joined i could make some friends that are interested in hacking as i am. however, i am new at this, i have been trying for a long ****in' time, and i am gaining more knowledge everyday and i am so close to being able to gain access but i am stuck. all i need to do is exploit the server on port 53. i am going to try sending a getadmin program. but thats only if i can get actual physical access to that computer. is there any way to send the file over the web without having to login to the server? or on telnet can i send a file without having to login somehow? i know these newbie questions are a pain in the ass to you but i really appreciate the help.
thanx
