AIF Activation Error

After installing AX 2012 CU6 on an environment I got the following error after trying to reactivate the AIF inbound ports:

Faulted: System.OperationCanceledException: AIF service group not activated.  Service group: AifGDS.  Error: There is already a listener on IP endpoint 0.0.0.0:8201.  Make sure that you are not trying to use this endpoint multiple times in your application and that there are no other applications listening on this endpoint. ---> System.ServiceModel.AddressAlreadyInUseException: There is already a listener on IP endpoint 0.0.0.0:8201.  Make sure that you are not trying to use this endpoint multiple times in your application and that there are no other applications listening on this endpoint. ---> System.Net.Sockets.SocketException: Only one usage of each socket address (protocol/network address/port) is normally permitted

I was confused about the wrong WSDL Port in the error cause the port of the AOS where I was working on was 8103. After some research in the WorldWideWeb I found a solution that solved this issue for me:

1. navigate to server bin folder:
   C:\Program Files\Microsoft Dynamics AX\60\Server\DAX2012\bin
2. open Ax32Serv.exe.config file in an editor
3. replace 8101 with your WSDL Port
4. replace 8201 with your servicePort

Getting access to SQL Server

Everyone of us knows the problem that after a SQL Server Installation you suddenly recognize that you have forgotten to grant your user access to the SQL Server instance.
Due to the fact that the NT AUTHORITY\SYSTEM account alwas has access to the SQL server a simple workaround is using PsExec. It allows you to run programs as the SYSTEM user.

1. download PsExec and extract it somewhere
2. open CMD and navigate to PsExec folder
3. start SQL Server Manager with the following command:
   PsExec -s -i "C:\Program Files (x86)\Microsoft SQL Server\110\Tools\Binn\ManagementStudio\Ssms.exe"

Add your user in the Security settings :)

For me this worked fine with SQL Server 2008 but seems to be not working with SQL Server 2012. You can get access to the SQL Server but you are not allowed to change Security settings or add users.
