I am having trouble with my session data on Microsoft IIS.

Here is a little background of the problem:


1)       I am not personally in control of our web server.  Our IT
department manages it.  They have IIS running on their sever and use MS SQL
Server, but they have allowed me to use PHP instead of ASP.

2)       I have Apache running on a local web server in our office (not the
IT department).  It accesses the SQL Server database remotely.  I have
register_global turned OFF and use the following code on each page: 





            Everything works PERFECTLY on my local system.

3)       I have ported all of my code to the IIS server location.  It
accesses the database correctly but displays an error message when I try to
use the session data.  It does NOT post messages that the session could not
be started (which is the normal sign of session data not being allowed).
The message says the variable does not exist.  It is as if the session is
started but the variables aren't being saved.


The question I have is:

What concerns should I have with PHP sessions when I move from Apache to


I do NOT need to know how to set up IIS to allow session data correctly
(that's the job of our IT department).  If this sounds like something our IT
department has set up wrong, please do not feel compelled to answer this
question.  I just would appreciate some advice on what I may need to change
in my own code so that it works with IIS instead of Apache.


Thank you for your time,
