FERNANDO - 2005-02-04

I am using phpdev423 for a small intranet(10 computers). There are 6 small databases that use the  web pages and there are some excel files that make SQL queries with the ODBC driver (MyODBC-standard-3.51.07-win.exe). There is no heavy traffic. The computer Im running is a Win XP P4/2.4Ghz  512 MB. My question: I have put 2 Ethernet cards, which doesnt work anymore, is it possible to screw up hardware (Ethernet card) with a bad configuration or bad usage of phpdev423?
