I've got two Vista Ultimate computers. Both have the same username and password. Same workgroup name.
Password protected sharing is enabled on both.
I shared a folder on computer 1, and added Everyone to the security tab, with full control.
When i try to map the folder from computer 2, I can see computer 1 listed. But when I click on the + next to it, it asks for a username and password (which I did not expect to be necessary since they are both the same user account and password) and when I enter it it says Logon Unsuccessful.
Any ideas where to look?
