Hi aju41
Sorry to hear you are having issues, setting up scanning on your 4150. below is a link to the 4150 support page describing how to setup the scanning to a PC or Mac.
http://www.support.xerox.com/support/workcentre-4150/support/enus.html
There are 5 related links listed at the bottom of the page. the 4th link in the list is "How To Create a Shared Folder on a Computer" and instructs you to disable/uncheck "Use Simple File Sharing". You can then create the folder share in any directory path you would like. I have my foilder named as "Scan" of the root of C:\.
