This morning I copied a file over to shared and the copy completed but the window didn't update and the file did not show up so I went to refresh the screen and got the error. If I wait long enough or go back and forth between different shares it will again become accessible but when I go to FS1 and restart the smb service I can again access it. It is happening very frequently. Almost every time I want to use the server for something.

Yes please ;-)

There is nothing really wrong with your smb.conf files, except I would 
remove the 'winbind enum' lines from FS1, all they really do is to slow 
things down. I would also add 'winbind refresh tickets = Yes' to FS1.

After this, you may have to raise the log level on FS1 to see if 
anything pops out.

What OS is this ?
