Pull down the Service menu and select "Set Service Account." The Service Logon Settings dialog box is displayed.
In the Impersonation options, enter the Domain, User name, and password you plan to use with the Alert Service.
Click OK to save the information.
Be aware of the following behavior:
If you are running the Microsoft Exchange client, the server name and mailbox must be specified. The mailbox account must be the same account that is specified in the Impersonation options.
When a Microsoft Exchange client, such as Outlook, is not installed on the computer where you are setting up the Alert service, the Exchange Server related fields are unavailable on the configuration dialog.
Optionally, the Alert Manager lets you set up alternative messaging services such as STMP, SNMP, Broadcast, Unicenter TNG, Lotus Notes, and so on.
