CIFS: Freenas not available if left alone for some time

[JohnD]

Hey,

I'm using freenas 8 with zfs and cifs guest authentification... and it runs fine. I have a Win7 64bit, a Win2000 and a macbook as clients (all cifs).

If i do not use the nas for some time (a few hours) and no client is connected all clients are unable to connect again.
I have to search for the nas in the network enviroment and after a few minutes the nas is available again (for all clients).
Does anybody know how to solve this issue???

Thanks.

JohnD
