Securing Myriad Terminals

By Richard Payne - Friday, March 3, 2006 10:05:00 AM

One of the questions that we are getting increasingly often is \"How do we prevent people fiddling with studio PC setups and breaking things\". The correct \"Windows answer\" is to make your users login as a restricted user. However this raises several problems on a Myriad system.

Myriad local configuration data is stored in an INI file in the Windows folder. This folder is not writable by restricted users and if you are running Q-Nxt it can't update the automation mode. If the terminal restarts for any reason then the auto-restart will not work correctly. Also if you are running AutoTrack on the same system then its configuration is stored here too with the same problem.

The solution is to set the security permissions on the INI files to allow full access to everyone. Select the myriad.ini (and autotrck.ini if you have it), right click and select Properties. Go to the security tab. Is \"Everyone\" in the list of users at the top? If not then click the Add button, select Everyone and click Add followed by ok. Once Everyone is in the list select it and make sure that Allow Full Control is ticked. Press OK to close the properties dialog.

Restricted users do not have permission to set the system clock. Normally this would be a good thing but if you use a radio clock then it is a problem. Myriad controls the clock, reads the time from it and sets the system time. The problem is that Myriad runs in the user's security context and so if the user is restricted so is Myriad and hence it can not set the system time. The only solution to this is unfortunately to relax the use restriction and allow them to change the time.

Go to Start > Settings > Control Panel > Administrator Tools > Local Security Policy
Use the tree on the left to navigate to Local Policies > User Right Assignment
Double click on the \"Change the system time\" entry in the list on the right.
Tick the local policy setting for the \"Users\" group and press ok.
Close the Local Security Settings window.

Remember that installation and configuration of a Myriad system require Administrator access. Therefore if your users do not have this then they can not make any changes. This also includes re-licensing of all P Squared products.

Another issue in Myriad v3 is the file that stores the Local Jump Buttons. These are stored in the folder that Myriad is installed into - typically C:\Program Files\P Squared\Myriad v3.

The good news for Myriad v3.5 users is that it stores the file in the All Users Application Data location (typically C:\Documents and Settings\All Users\Application Data\P Squared\Myriad v3 ) so you shouldn't need to alter any permissions to make it work Smile
