Solaris

Sorry I know this is off subject but I'm in a bind. I have a problem with my Solaris box booting up. Does I fairly new to all of this so does anybody know a good newsgroup for Solaris?? My problem is I added a file so a program would auto load. I added the file to etc/rc2.d Now this program loads perfect but continues to run and the rest of the O/S can't load. How can I access that director to delete the file?? Thanks for any help.... Kris
