Yes all computer names are different. I had that issue when I networked a clients office for digital radiography. He bought 4 dell boxes and they all had the same computername which was an issue.
My user account names on each computer is the same. Tried renaming my user account and nothing changed.
As for the work group, the 4 win 7 boxes are WORKGROUP and the Vista box is MSHOME as it was part of an old network. I never bothered changing it because I can access its shared folders and it can acess all machines on WORKGROUP. the issue is only between the win 7 boxes.
Let me see if I can make it a little clearer an we will deal with only 2 win 7 boxes on Workgroup.
Box A cannot access shares on box B when I am logged in with my user account.
Box A will access shares on box B when I am logged in under a different user account. (I just added a second user account. Didn't configure anyting)
I ran network diagnostics under my user logon and under the shared folders test I enter the path \\BoxB\users
and get the following results:
Verify the permissions settings on "users"
You dont have permission to access the share.
I then switch users to the newly created user account and run the same dignostics and Windows cannot identify the problem (because there is no problem).
It seems that there is some setting or parameter in my user account causing box b to reject my attempt to access. I dont think it is a permissions setting in box B as the secong user account had no problem accessing. its not hardware related. What do I look for?
once I get this one resolved maybe all the other issues will go away.
