Network Account Utility
- The Change
Network Account utility is a tool you can use to manage credentials for
node-to- node communications between ArchestrA components.
- During the initial installation of an ArchestrA
component, you are prompted either to create a new user account or to use an
already existing account, and provide a user name and password for that
account. The same account must be used on each computer that requires
communication with others in the ArchestrA
environment. Use the Change Network Account
utility to change
this data, if necessary, on any computer after installation of an
ArchestrA component.
- Node-to-Node
Communications
- All computers that have installed ArchestrA-enabled software must be able to communicate with each other. This communication is enabled through an ArchestrA-specific user account set up during the initial installation of an ArchestrA component on each computer.
- Subsequent installations of ArchestrA components do not prompt for user account information. They automatically use the account set up during the installation of the initial component.
To recreate an ArchestrA user account
Start the Change Network Account utility by selecting Start--> All Programs/Wonderware/ Common/Change Network Account.
- The Change Network Account dialog box appears
- The data shown in this dialog box are those settings entered during the initial installation of an ArchestrA component on the computer. The password options are shown blank for security reasons.
- The Change Network Account utility allows you to change the current data shown in the dialog box, including:
- Changing the password of the current account.
- Creating a new local user account.
- Using an existing local machine or network domain account.
- In a single-node ArchestrA system, create any account.
- In a multi-node ArchestrA system, recreate the same user account with the same user name and password that was created on all other computers that have installed ArchestrA-enabled software.
- Once you have configured the account, click OK.
