Hi Michael,

thanks for the input.

Forgot to mention it: The shares are located on a Synology NAS joined to 
my little domain. So there has nothing changed, but to be sure I've 
checked it. I have just once to logon to Windows with full rights and 
after this it works again with normal rights. I even don't have to open 
the shares for this this.

And - as mentioned in my first mail - this only happens on my Windows 
clients. A mount from a Linux client works without such doing.
