I actually know exactly what the problem is.  The 1.4.x file servers
implement a change to prevent unfriendly clients from repeatedly
requesting FetchStatus operations on the same object.  The 1.4.x
and earlier Windows clients do not implement the InlineBulkStatus
operation.  This was first implemented in 1.5.3.  Without
InlineBulkStatus, when Windows attempts to perform a status operation
on each of the files and directories within a directory that has 'l'
but not 'r', the FetchStatus operation will fail.  Therefore there is
no data to cache and the client must repeatedly query the server.
This triggers a backoff algorithm to slow down the client.  In turn
the SMB client is breaking off the connection and ....

In other words, it is a change in the 1.4.x servers that is hurting
you.  The 1.5.8 Windows client will save you.
