win2000

Hello all. At home i have a windows 95 machine with apache, pws mysql and mysql. I followed the installation instructions and it worked fine. I got a new job and at work everything was win2k. Before i got to my own machine at work i installed php on my bosses machine wich was running IIS and of corse personal web manager. I installed php there.. Again no problem. I got my own machine at work. I installed win2k and all the same stuff on my machine including IIS. then i installed php exactly the same as i had on other machines and all i get the expected headers error message. I followed the instructons to the letter as i had done every tme before. I even got fed up with iis and disabled it in favour of apache. I tried setting that up according to the instructions and guess what. Server errors. Any ideas? Yours going mad Darren
