Hello David,

First, all questions related to MS4W should be sent to the MS4W-users 
mailing list, where hundreds of users and devs can assist you with your 
issues (subscribe at http://lists.maptools.org/mailman/listinfo/ms4w-users).

As you mentioned, MS4W is designed for new installations and contains a 
ready to use Web server and everything you need to move forward.  If you 
need to use MS4W in an existing environment, there are some options:

  - follow the existing notes to install in other environments in your 
local README file 
(http://www.maptools.org/ms4w/index.phtml?page=README_INSTALL.html#k-installing-the-ms4w-mapserver-binaries-in-other-environments)
  - search the MS4W mailing list for other users asking this same 
question and the responses (search at: 
http://osgeo-org.1803224.n2.nabble.com/ms4w-users-f4995553.html)
  - contact me directly for assistance

Hope that helps.

-jeff

Phil,

In recent versions MapServer aggressively keeps single raster files used for
raster layers open even after the map is destroyed in order accelerate the
next access to it.  This can be controlled/disabled by adding the following
line in your raster layer:

   PROCESSING "CLOSE_CONNECTION=NORMAL"

The default setting is DEFER for raster files.
