Software Deployment

Hi,

We are in the middle of a big migration where I work where we at the same time lock down the client environment so that users are just "users" on their machines instead of local admins. We repackage every applications accordingly with often means giving access to a folder or a registry key. But now I´ve stumbled upon an error in an application which I can´t seem to figure out.

The error is that in a calender within the application, the highlighted day which is suppose to be current date isn´t the current date but the first of the month. It works just fine if I grant the user local administrators right. But it doesnt work even if I give change rights to every file on the entire harddrive and every registry key in the registry. So there must be a policy or something that has to be changed. Or what do you think?

So if I cant use regmon or filemon to track this thing down, what tool do you suggest that I use? Ideas would be appreciated!
