Platform/configuration = (NT4/SP6)

I have created a batch file that opens MS Access and runs a macro... This macro does 3 things:
1. Deletes a table
2. Imports a delimited text file into a new table
3. Quits Access and Saves All changes.

Here is the batch file:
REM   Defines a path for the Microsoft Access executable 
PATH = "C:\Program Files\Microsoft Office\Office\"
REM   Starts Microsoft Access and runs the macro.
START /WAIT Msaccess.exe "C:\inetpub\wwwroot\webcolor\webcolor.mdb" /x "Importer"
EXIT

When I call this .bat file with the exec() or system() functions, the browser hangs and when I check the Task Mgr... I have php.exe, CMD.exe, and msaccess.exe all hanging (and I also can not end the processes - Access is denied). For every page access, an addition 3 processes open and hang.
