There's a fundamental difference: NFS is stateless, which means that
you don't "reestablish connections" because you don't have a connection
to begin with.  It's a little like HTTP in that each network request
stands completely on its own.  So if a server goes down and comes back
up, there is nothing to re-establish -- it just starts responding to
requests again.

For SMB you have to accomplish the same effect by detecting that a
connection is down and reestablishing it.  It can be done, of course.
Windows machines do it.

Windows machines just reestablish the connection on demand.  You'll
notice that if a share is idle for awhile and you try to access it,
there'll be a short delay.

You know how Windows 98 has an option for "quick logon", meaning don't
connect to shares until you actually need them?  That's part of the
same mechanism.
