Problem with Intel Xeon

OS: Win 2000 Server Family HD: HP WorkStation Intel Xeon (Dual Processor, installed only once) Apache: Apache/1.3.24 Php: PHP/4.2.0 DB: MySql 4.017 I've instelled my php software under 20 pc, but only in this (Hp Intel Xeon) i find this rondoom error "Parse Error: T_CONSTANT_ENCAPSED_STRING" in my files? Why? In all the other computer i haven't this problem, wich seems to be randoom in all files and not only relative to a string but also a connection to db or other line. Why? it is possible a cause the inclusion library (i use the include_once() function)? But is very strange, if is an error of parsing, why this is visible only under this machine?? Thanks
