Please find attached file for screenshots of problem. i am stuck up with this problem. please help in this regard. 

Hi Faisal

In the Simatic Shell I can see only the Server, the CLIENT2, CLIENT3 and CLINET4
But the CLINET5, CLIENT6 and CLINTEN17-PC is missing
You must see al computers on the Simatic Shell

1. Please check the requirments of a windows network for WinCC described in the following FAQ: 
What are the requirements for operating SIMATIC WinCC in a Windows network? http://support.automation.siemens.com/WW/view/en/868014 

2. Please use from the operation system the same user and password for die server an client
Is the User included in the group Simatic HMI ?

3. Start the Simatic Security Control on the CLINET5, CLIENT6 and CLINTEN17-PC and restart your clients

4. In case that will not solve the behavior please regenerate the server data on the server, load the server data from Client  and afterwards try to connect the clients again.

Best regards
