Wait...  From a Windows Server, or OF a Windows Server?  In any case, 
"Windows Server" describes at least four completely different operating 
systems and dozens of flavors of Windows, so you may want to go the 
extra mile and actually report the actual operating system, because why 
not?  Common problems will differ on each platform.

This error message is the Samba end-of-chain -- in other words, it's 
preceded by the actual error message, and this is really just Samba's 
odd way of saying "something terrible went wrong higher up in the 
stack."  Samba encompasses four different protocols and has different 
quirks over four major versions, and can be configured in hundreds of 
different ways on the server -- without the actual error message or 
versions of either Windows or smbclient, the best you can hope for is 
thousands of possibilities from higher up the chain that may or may not 
have any relevance to the issue you're having.

Of course, the main issue with smb in general is that open files can't 
be read.  Sometimes this is fatal, sometimes not, depending on all kinds 
of things.  Before jumping to conclusions, though, I recommend running 
smbclient verbosely and getting the actual error message so you know 
what to take a look at.

Without the error from higher in the stack, the best anybody could do is 
give you one of many, many possible causes that may or may not relate to 
the issue you're experiencing.

That depends on the root cause.
