This means the default password SiteKiosk uses when it creates the Windows user account does not meet the requirements your IT department has set on your network. You will need to install SiteKiosk from the command line.
Here is the information for set-up of the SiteKiosk software to change the SiteKiosk user password on installation:
1. Start by clicking Windows Start button then type cmd and press Enter.
2. In the Command prompt window, type this line exactly. You will also need to either add the path in front of the exe file or the directory that cmd is pointing to
3. NOTE: Change the “12mypasswd” to a password of your choice that fits your network restrictions. You will need to change the directory of the command prompt to where the file is saved.
