Troubleshooting Permission Problems

Throughout MessageStats, there are several locations in which you can specify the security context for the MessageStats scheduler service and for gathering tasks. To allow task gatherings to run in their own process, MessageStats requires that the full user name and password be provided and saved.

When the password for an account that is used in MessageStats is changed, it affects how MessageStats performs. You can also see these issues if an account that is used in MessageStats is disabled or is no longer available.

There are two main areas of MessageStats in which security credential information, along with passwords, is saved. The areas are as follows:

•
MessageStats Scheduler Service
Windows Service—Account that is used to start the MessageStats Scheduler Service. The account can be modified using the Windows Service Control Manager (SCM). For details, see Updating the Scheduler Service Security Context .
DCOM—Credentials that are used to instantiate the MessageStats Scheduler Service COM object. This can be modified in the DCOM Config section of Windows Component Services. For details, see Updating the Scheduler Service DCOM Credentials .
If you have the MessageStats client console installed on the computer that hosts the MessageStats Scheduler Service, you can update both the Windows service account and the DCOM configuration using the Scheduler Service Credentials property tab for the MessageStats Server. For details, see Updating Security Credentials for the Scheduler Service .
•
MessageStats Tasks
DCOM—Credentials that are used to instantiate the MessageStats Task Processor COM object. The credentials can be modified using the DCOM Config section of Windows Component Services. For details, see Updating the Task Processor DCOM Credentials .
If you have the MessageStats client console installed on the computer that hosts the MessageStats Task Execution Server, you can update the DCOM configuration using the DCOM Credentials property tab for the Task Execution Server. For details, see Modifying Task Processor DCOM Credentials .
Thread—Credentials that are used to execute a processing object. When a processing object is created, it is created using the DCOM object. A background worker thread is then created that takes on the credentials. The credentials can be modified using the MessageStats Console, in the properties for the task. For details, seeChanging Task Credentials .

If a password is changed, there are different security credentials that you must update for each area to ensure that MessageStats operates correctly.

What are the Symptoms of a Permissions Problem?

This section explains the symptoms that occur if an account is invalid because it does not exist or is disabled or for which the password has expired. Details are provided about how to diagnose if one of the accounts is not valid.

Symptoms of a Problem with Scheduler Service Permissions

The credentials for the MessageStats Scheduler Service are not widely used so it can be difficult to diagnose if the account password is suddenly invalid. One of the following symptoms can indicate a problem with the account used by the scheduler service:

•
The MessageStats Scheduler Service is restarted (either explicitly or due to a machine reboot) but the service fails to restart.
•
Within the MessageStats console, you see an error page titled “Unable to Connect to MessageStats Service”. It states that there may be a problem with the account used to run the service, or with the configuration of the DCOM and the RPC service on the computers that host either the scheduler service or the console.
•
You see “Access Denied” error messages when you try performing console operations such as navigating the tree or opening property tabs.
Symptoms of a Problem with Task Processor Permissions

For the MessageStats tasks, an indicator can be that some (or possibly all) tasks immediately fail when they are run. If the task credential information for a task is incorrect, any execution of that task continually fails. Error details are provided in the task log.

If you view the log and see the following error text, the problem is that the credentials for the task are invalid and must be corrected:

The task activity item was unable to execute due to a problem with the task credentials. The user that was used to execute the task activity item is Domain\User.

In this case, you would correct the credentials that are specified for the task. For more information, see Updating Default Credentials for Tasks .

Another symptom might be that task occurrences do not appear in the Task Status view in MessageStats console.The task never appears to be running. Even if you force the task to run using the Run Now command, the task does not appear to start.

Usually the root cause is a DCOM problem. Before a task can perform the gathering work, the task job is created using the specified account. If task creation fails, the task does not appear in the task view. You must correct the credentials used by DCOM for the tasks to execute correctly. For more information, see Updating the Task Processor DCOM Credentials .

Updating Scheduler Service Permissions

For the MessageStats Scheduler Service, there are two locations in which credential information is stored. You can update the account information using two different methods:

•
If you have the MessageStats client console installed on the computer that hosts the MessageStats Scheduler Service, you can update both the Windows service account and the DCOM configuration using the Scheduler Service Credentials property tab for the MessageStats Server. For details, see Updating Security Credentials for the Scheduler Service .
•
If you want to update the credentials directly in Windows, see the sections that follow:
Updating the Scheduler Service Security Context
Updating the Scheduler Service DCOM Credentials

Updating the Scheduler Service Security Context

The first location is in the Windows Service Control Manager (SCM). This is the location in which all Windows Services are defined, along with the security context under which the service runs. You can access the SCM in different ways. The simplest way is to select Control Panel | Administrative Tools | Services.

To update the password for the Scheduler Service
1
In the list of Windows services, select the Quest MessageStats Scheduler Service.
2
Right-click and select Properties.
3
Click the Log On tab and update the password.
4
Once the password is corrected, start the MessageStats Scheduler Service and ensure that the service starts without errors.
