Setting Up Guardian Options, User Accounts, and User Levels

Once the Guardian key is installed (see Installing Keyed Options for more information), you can define your TRIOS options and set up your Guardian user accounts.

Guardian Options

Once the Guardian key is installed, access the Guardian options by clicking the TRIOS button , and then select Options > Guardian from the tree view. Select from the following options:

• Enforce Authorized Windows Users: Select this option to restrict the access to TRIOS software to only the users in the authorized user list (per computer installed).
• Results Log: Select this option to save a record of the analyses and other results events that occur after file creation within the data file.

Both of the above options should be enabled if you are working in a 21CFR11 regulated environment. If you later wish to disable Guardian, uncheck both of these options.

Guardian User Accounts

The Guardian option is coupled to the Windows User accounts (both locally and on the domain). Therefore, for unique identification, each operator can have a unique Windows User ID.

Select from the following topics:

• Adding Users
• Removing User Accounts
• Setting User Levels

Adding Users

To add users, follow the instructions below.

1. Click the TRIOS button , and then select Options > Guardian from the tree view. Any users that have previously logged into TRIOS appear pre-populated in the Enabled Users list.
2. To add additional users, right-click inside the Enabled Users window and then select Add User.
3. Now click the User Name drop-down arrow and select the appropriate user.
4. Repeat steps 3–4 for each additional user.
5. NOTE: Users can also be added by manually typing \user name after the computer or domain name.
