Guys, I don't know if this was actually answered, but there's also a problem with the PC names. (I didn't want to read 11 pages
You must have different PC names.
For changing this or verify go to :
Computer>System Properties>Advanced System Settings.
Under the tab "Computer Name" you should see the Full computer Name. This MUST NOT match the other computer which you were trying to access. If they do, just change one of them by clicking "Change..." and writing a different name where it says "Computer name"
Reboot, and that shall do it
