Account is Locked Out

My company uses login script to map shared drives for all staff. Recently there are about 3 users who cannot access their shared drive. An error msg popped up saying “Your account has been locked out. Pls contact your Administrator”. I’ve checked in AD that their account is not locked out at all. It’s definitely not a PC issue has it is the same wherever they logged into. Also their login script failed to run. It seems like the 3 of them had ran some macros in Excel before hand and then the shared drive stopped working. Does anybody know what’s going on? Any help is appreciated.
