Homegroup asking for Username and Password

Blisterman

I'm at my wit's end with this one.

I've set up homegroup in windows 7 to share files between the computers in my office. It worked perfectly, until I decided to change my computer's name. Ever since then, whenever somebody tries to access my files, a box comes up saying "Enter Network Password", asking for a username and password. I changed the computer name back, and it's still happening.

I've tried everything. Setting up new accounts in windows, starting a new homegroup, disabling passwords, disabling windows firewall. I've even reformatted the hard disk and reinstalled windows. It still keeps happening.

Open network and sharing centre and try deleting the network profile on all the computers and create new network profiles.
