Problem

After installingSQL Server 2017 orSQL Server 2016, a user tries to connect toSQL ServerIntegration Services (SSIS) for the first-time usingSQL Server Management Studio(SSMS), mostlikely the connection attempt will fail. The received error messageindicates: Failed to retrieve data for this request. Connecting to theIntegration Services service on the computer failed with the following error:'Access is denied.' By default only administrators have access to theIntegration Services service. On Windows Vista and later, the process mustbe running with administrative privileges in order to connect to the IntegrationServices service. See the help topic for information on how to configureaccess to the service.

For users who have worked with older versions of SQL Server,this can be surprising as connecting to SSIS with SSMS usually does not have problems.The reason for this is that in the older versions, all users of the 'Users' grouphad access to SSIS by default. In the newer versions of SQL Server, however,access is secure by default and it must be granted to a specific user who needsto connect to that service.

Solution

In this article, we will reproduce this problem and describe how to solve it.

Let’s assume that we have SQL Server 2017 installed and never connectedto SSIS before on that server. SSIS should be running, which can be checked in SQLServer Configuration Manager as follows:

To connect to SQL Server Integration Services, we open SQL Server ManagementStudio and in the 'Object Explorer' choose 'Connect'and then 'Integration Services…':

Now, we need to log in with our credentials:

After clicking 'Connect', the following error message will appear:Failed to retrieve data for this request. Connecting to the IntegrationServices service on the computer failed with the following error: 'Access isdenied.' By default only administrators have access to the IntegrationServices service. On Windows Vista and later, the process must be runningwith administrative privileges in order to connect to the Integration Servicesservice. See the help topic for information on how to configure access tothe service.

The problem is that starting from SQL Server 2016, Users in the 'Users'group do not have access to SSIS by default. Therefore, if we have just installedthe services, but haven’t granted the special permissions to the user, itwill be impossible to access SSIS by using the credentials of that user. Thus, weneed to manually grant these permissions using an Administrator user.

First, we should open a 'Command prompt' and type Dcomcnfg.exe:

This opens the UI for working with 'Component Services' wherewe can change certain settings in the registry:

Then we locate 'DCOM Config' under the 'Console Root'- Component Services > Computers > My Computer > DCOM Config. Underthe 'DCOM Config','Microsoft SQL Server Integration Services'can be found. Right-click on it and choose 'Properties'.

Then, in the 'Properties' window, we select 'Security' tab:

Here we should set 'Launch and Activation Permissions' and'Access Permissions' for our user.

Click 'Edit' on 'Launch and Activation Permissions'.

Then click 'Add' we find the user and grant the correspondingpermissions shown below:

After that, we set the corresponding permission for the user on the 'AccessPermissions' in the same way as shown below:

Having set the necessary permissions for the user, we should restart SQL Server Management Studio and Integration Services:

When we open SSMS after restarting, try to connect to Integration Servicesagain and the attempt should be successful:

Hence, the problem is solved, and the user can work with SQL ServerIntegration Services using SQL Server Management Studio.

Conclusion

In conclusion, as we can see above, in order to be able to connect to SSIS inSQL Server 2016 or 2017, we need to do additional manual work to grantpermissions. This is because unlikethe older versions of SQL Server, in this version access to SSIS is secure by default.Therefore, if the current user needs access to SSIS, the administrator should manuallygrant access to that user as shown above.
