During installation of the Business Notification Server, you have to enter the name and password of a Windows user (domain user). This user is used for the following purposes:
The Business Notification server-side applications and services are running under this user account.
This user account is used for logging on to the SQL Server.
If, or when, the password is changed - maybe because your company has a policy of enforcing password changes at set intervals - you have to perform the following procedure in order to ensure that the new password is used by the Business Notification applications and services:
On the computer that runs the Business Notification Server components, locate the folder where these components are installed (the default is "Program Files\MicrosoftBusinessSolutions\Navision\BusinessNotification\InstallUtility." There is a small utility in this folder, called "aspnet_setreg.exe."
Open the Command Prompt window in this folder.
At the command prompt type:
"aspnet_setreg.exe
-k:SOFTWARE\Microsoft\BusinessSolutions\BN\identity
-u:domain\username -p:password"
where you replace "domain\username" and "password" with the domain
and username of the account in question and the new password.
This will reset the cached password that the server components are using with the new one.
More information is available here.
Furthermore, you have to manually set the new password for two services on the computer that is running the Business Notification Server components:
Open the Services application (click Control Panel, Administrative Tools, Services, or the equivalent command - the location in the menus vary from one operation system to another).
Locate the service called "Notification Service Deployment Manager."
Right-click the name, and then click Properties.
Click the Log On tab and change the password.
Locate the service called "NS$BusinessNotificationInstance."
Right-click the name, and then click Properties.
Click the Log On tab and change the password.
