i have a biztalk - window service tied middleware application which talks to other system.

recently we had a request to test for scenarios which relates to the date.

as we have a lot of places in the application which uses the .net Datetime.Now value, we don't really want to go into the code level and change all these values.

so we're looking at the simplest way to test which is to just change the OS time.

but what we notice is that sometimes when we change the system date time, we will get account lock out due to Active Directory.

1. So my question is what's a good and safe way that i can test for future dates, etc by changing the windows OS system date time but without causing any issues with the Active Directory.
2. And where can i find out more about AD and how it issues token and what's the correlation with the system date time changes.

Thanks! ~m
