RESOLUTION #1:
When executing scripts on a Toad Intelligence Central server, Toad uses the server's Local System user account by default. For best results, give this account all the necessary permissions to successfully execute Automation scripts on Intelligence Central.
RESOLUTION #2:
If it is not possible to grant the server's Local System account the necessary permissions to run all Automation scripts successfully, an alternative is to configure Intelligence Central to run under another account that does have the correct permissions. To use this workaround, configure these three services: Toad BI App Server, Toad Intelligence Central, and Toad Intelligence Central Proxy.
To run Intelligence Central under a different account
1. Open the Windows Local Services manager (example in Windows 7 environment):
Control Panel | System and Security | Administrative Tools | Services (Local)
2. Or click the Start button, enter services.msc in the Search field, and press Enter.
3. In the Services manager window, right-click Toad BI App Server and select Properties.
4. In the Properties dialog, select the Log On tab.
5. Select This account and enter the user name and password for the alternative account with necessary permissions.
6. Click OK to save your modifications and close the dialog.
7. Repeat for Toad Intelligence Central and Toad Intelligence Central Proxy.
8. Then restart each service to apply the changes.
