How to: Change the Windows Account for an Instance of Notification Services (Services Manager)
Each instance of Notification Services has an engine on each server that runs a hosted event provider, generator, or distributor. Typically, the NS$instanceName Windows service runs the Notification Services engine. The Microsoft Windows service runs under a Windows account, which can be changed using Services Manager.
If you change this account using Services Manager, be aware that if using Windows authentication, the Windows service uses the account to access SQL Server, and the account must have specific permissions in the instance and application databases.
To change the Windows account
In Control Panel, open Administrative Tools and then open Services.
Double-click the NS$instance_name service, and then click the Log On tab.
Type the account name in the This account box, and then type the password in the Password and Confirm password boxes.
Note
Microsoft does not recommend using the Local System service account because it is a highly privileged service account on the local computer and is not able to access network resources.
Add the account to the SQLServer2005NotificationServicesUser$ComputerName Windows group. This provides access to the Notification Services binaries.
