I am trying to replace office equipment, before we all had Windows XP, I am replacing the machines one at a time with Windows Vista. I am working with the first two to get them network and I can see the other hardriver/documents etc. but when I click on it it says windows can not access (inserts the drive and computer name) check for user name and password. With these, I plugged them in and they detected each other, we can both get to the 3rd computer with no issues, we just can't get into the Vista machines without getting asked for a user name and password. I have changed it in the permsissons part of the network guide, but that didn't work. Any help would be appreciated.
