I've had the same issue.
I've enabled passthru authentication for CIFS against a SMB server.

My file-servers-custom.xml looks like this:

Hi,

I have exactly the same error.

Our Alfresco 2.1 instnace ran on a Linux server for 1 year without any trouble. Last wweek the message has appeared and now users can't mount CIFS access.

Did you find an answer ?
