All of a sudden user login & pw do not work (only one login & pw were setup) and we cannot access program (either Manager or POS). Only thing that changed since the last time POS was opened on Sunday was a WIndows Update & perhaps a Java update. Also Sunday at closing, we tried to change back up to an alternative server directory and the system would not allow the change. Other then those few things, nothing else was done to settings/software.
Any help would be appreciated.
