Host’s installation is invalid

The following error shows when try to add a host in Performance Center 11.0:

Host’s installation is invalid error

When the patch 2 is installed it updates the file LTS.config, also the configuration wizard updates this file, but using the original version.

in this case Installing the patch updated the file but when the configuration wizard ran again it changed the file using a non updated version.

1- The logs from the host machine shows 0 KB or not recent updates, this means there’s not even a connection established.

2- in this case w3wplog.txt file contained the following line:

System.ServiceModel.EndpointNotFoundException: server —> System.Net.Sockets.SocketException: No connection could be made because Could not connect to http://<PC_server_address>:<port>/LTOP/HostManagementService/HostManagementService. TCP error code 10061: No connection could be made because the target machine actively refused it <PC_server_address>:<port>. —> SysteHm.Net.WebException: Unable to connect to the remote the target machine actively refused <PC_server_address>:<port>

3- Accessing the URL in the log http://<PC_server_address>:<port>/LTOP/HostManagementService/HostManagementService give not result, it means there is not connection or the port is not enabled.

4- using Netstat -a in the Host machine is possible to see the <port> is not enabled. This means the Performance Center Load Testing Service was not running.

5- When try to initialize the service it couldn’t be initialized, however this creates an event we can check in the Windows Event Logs for further details:

As you can see the error was for the LTPSvc, it mentioned in the details it cannot recognize the attribute ‘ltopPort’ in the file C:Program Files (x86)HPPerformance Center HostdatLTS.config

6- After the patch 2 this line is removed and during the configuration wizard it was added again. So go ahead and delete the ltopPort attribute including the value, save the LTS.config file and start the Performance Center Load Testing Service.

7- Now the Service is started, add the host again.
