IIS 5.1 & networking

I have installed IIS 5.1 on my Win XP Pro machine and everything was sweet. Access and sql DB interaction and other asp was working like expected. BUT: then i started using mozilla firefox. The error with firefox states " The specified module could not be found. " and with IE it workes perfectally. Im trying to use the scripting.filesystemobeject thingy and no, its not Norton Anti-Virus, ive disabled script-blocking.

I work with a web design company part time doing web mantainance and the web dev. man said that its a network problem and IIS and the ActiveX component in IE was compling the code.

Has anyone got any ideas? Im really confused!

Thanks all for your time...

It's pretty hard to guess from what you posted, other than to say reinstall FireFox.

You may get a better response if you posted some actual details about your problem.

Thanks for your thought and time but i worked it out:

It was a permissions problem IE has some kind of windows loggin and in the IIS 5.1 setting you can resrict users only logged into this PC. But firefox doesn't have that component or feature included in the program.

Thanks...
