Solution:

IMPORTANT: This article contains information about modifying the registry.
Before you modify the registry, make sure to create a back up of the registry and ensure that you understand how to restore the registry if a problem may occur.
For more information about how to back up, restore, and edit the registry, please review the relevant Microsoft Knowledge Base articles on support.microsoft.com

This is a known issue and the solution of this is to set the registry key "MaxObjects" to lower value than its current value.

Customer needs to lower the value of registry key "MaxObjects" to say 25 or 50.At present customer has set this value to 500 (The default is 100).Thus, by reducing the value of this registry key to 25 or 50 this error will be resolved.

Reason for this error
On clicking any object type in the System Configuration tree, Admin UI sends a request packet to policy server. In the case when the value of "MaxObjects" is set to 0x64 (100), Policy server sends back first 100 objects of that type (if number of objects is more than 100) in response to Admin UI request.

For Admin UI, response packet's buffer size is defined as value 256*1024 (the default value). Same value is defined in Admin GUI java applet to receive the response. In the above mentioned case, response packet's buffer size is exceeding value 256*1024 for 100 objects. So policy server is sending an error message: "SM Admin Server Error: Too many items in return list (Error 50)".
