First of all you have to share out drive E and then configure the security permissions. If you right click on drive E and select properties - sharing - advanced sharing - and then tick share this folder - click permissions - you can give the everyone group full control. Then you click on the security tab and again add the everyone or the name of the computer and give full control. If you browse to camilla3 eg: \\camilla3\share name and you can then mapped a drive if you like. You can also mapped a drive through cmd eg: net use j: \\camilla3\share name
Hope this helps.
