Windows Vista Networking a drive

How can I define a (USB) drive as a Network folder?

If I select Network File and Folder Sharing the drive shows J:\ Not shared and the Share button is greyed out.


If I try Tools / Map Network Drive I am presented with all of the unallocated drive letters so that I cannot define, (select), drive J.


I'm sure this was easier in XP - or is my memory failing me?


I can certainly share any files on the drive but that seems to be too tedious when a simple drive share would give me easy access to any folder below the root folder.


Is it possible, or am I being too ambitious?

 

Thanks. However, both File sharing and Print sharing are turned on via the Sharing and Discovery section of the Network and sharing centre.

Is there another option somewhere that I have missed?

 

Something more subtle that that I suspect.

Checked with both Firewalls, McAfee and Windows Defender.

Disabling either as a quick check made no difference.

 

Yes indeed, that does work for any folder on the drive, but when I right click on the drive and select Sharing the Share button is greyed out.

Therein lies the problem.

 

Arie, many thanks for pointing me in the direction that I was too stupid to recognise!

I had used the Advanced Sharing button, looked at it, but obviously not closely enough, and so I had completely missed the 'Share this folder' check box. No excuses - or perhaps I should just blame my optician.

Seems like I'm making a habit just lately of asking the blindingly obvious.
