Something like this is quick, dirty, and ought to do it:

@echo off
set SCRIPT_DIR=%~dp0
REM Set up mounts
%SCRIPT_DIR%bin\mount -u "%SCRIPT_DIR%" /
%SCRIPT_DIR%bin\mount -u "%SCRIPT_DIR%bin" /usr/bin
%SCRIPT_DIR%bin\mount -u "%SCRIPT_DIR%lib" /usr/lib
REM Start the Cygwin shell
call %SCRIPT_DIR%cygwin.bat
REM Clean up mounts
%SCRIPT_DIR%bin\umount -uA

(put it in your Cygwin root on the file server, won't work on Win9x/ME).

Note that this will trash the user mounts in your existing Cygwin
environment on the client (if there is one).  Detecting existing Cygwin
user mounts using the mount command is left as an exercise for the reader.
