Reference MS KB Q149582

During Y2K testing with Windows NT Server 4.0 (SP3) I cam across this
problem:

The Year 2000 is a leap year.

Using User Manager for Domains, try to set an account to expire on
2-29-2000.

I was returned the error message "February only has 28 days in this year."

I tried to set the account expiration to 2-29-2002 and got the same error.

I tried to set the account expiration to 2-29-2004 and got success.

-----------------------

This is a serious error.  For some reason, MS is not using a correct date
calculation method when UsrMgr performs its error checking (or has an even
more serious problem w/ UsrMgr interpreting the date).

This was reported to MS today.  There is no eploit available here, but it
is a functionality issue with NT.
