EDIT: Nevermind, I got the ndis.sys from my laptop...duh....didn't even occur to me. Thanks for you help though, you helped me save my computer from reformat and reinstall! Hey guys, I was wondering if you would send me or tell me where I can get a copy of the NDIS.SYS file? I have the same problem as above, I can't log into my XP Pro SP2 normally, only through safe mode and my 275Kb ndis.sys file was modified just this morning. I'm a moderator on other sites (not computer related) so I know what it's like when some dude shows up and wants some help and will be gone after his problem is solved, so I can understand if you get irritated at my request to send me the file...but if you could just point me in the right direction, I'd certainly be appreciative (for example, if I can just extract it from my XP disk?) Bill Gates may have created Windows, but it's guys like you that keep him in business. Sincerely, T.E.
