odbc connections

A colleague of mine has a problem;
"Has anyone ever experienced the problem of creating a System ODBC and it doesn't display in the ODBC administrator applet?"
was hoping someone here could help...What is your exact problem?|||the problem was that when created a new odbc connection this was not displayed...i have since discovered a reboot fixed it-i was under the impression that the sql server would have been rebooted first...dont worry about it!
thanks though
