Boot into run level 1, bring up auxillary services one by one waiting  
to make sure each works until you reach the one that borks, then  
reboot into level 1 disable problem service, go into run level 3, then  
diag config file and figure out what broke.

My bet is samba and some script that is kicked off when user's connect.
