Strange Session Issues

I posted a question earlier, but I don't think I explained my problem all that well. I am having problem with sessions on my W2K box. I can start sessions and register variables but I can't, however, seem to get the contents of the registered variables written. When I open the session file (the actual physical file located on the server), this is its contents: !sess_user|!blah|!sessUserClass|!sessFormData|!oUser| Each of those variables should have some data associated with them. Please note that I have not added the '!' to the variables. I don't think I am having file permission problems because some data is actually being written. The only data missing (and the most crucial) is the contents of each those variables. Does anybody have any suggestions? Thanks! alastair
