I have made user shares hidden now connection fails.

A. To hide a share all you need to do is add the $ sign to the end, for example, \\server\share$.

If previously in your logon scripts you had the command

net use f: \\<server>\%username%

it will no longer work as the share is hidden with the $ and to connect you will need to specifically specify the $ so change the command to

net use f: \\<server>\%username%$
