Services will not start after machine reboot

 Apache, ViewCVS, and MySQL Server are not working on my Redhat Linux       
 server. The server was rebooted after an error occurred(windows display    
 would freeze up and boot would not finish).                                
                                                                            


                                                                            
 Now when I try to start Apache (/etc/init.d/httpd start), I get this:      
 DocumentRoot must be a directory                                           
                                                                            
 But the DocumentRot is set correctly, it just has something to do with     
 security privileges on the machine.                                        
                                                                            
 Also, I cannot start MySQL (/etc/init.d/mysqld start)
