This allows us to avoid sending some somewhat newer requests that the server can not handle and go directly to the older version (infolevel) of the same call. Make sure we try to negotiate a level which allows us to get the server OS (which we check so we can detect Win9x vs. other legacy servers and eventually work around the Win9x DOS time bug (they reverse date/time fields).
