2. Expand the following key:
   
   HKEY_LOCAL_MACHINE | SOFTWARE | NetIQ | AppManager | 4.0 | NetIQmc | Security 
   
3. Open AllowMS and enter the names of the management servers that you want to communicate with the managed clients. Enter an asterisk (*) to allow all management servers to communicate with the managed clients. Names are separated by commas without spaces. For example: Shasta,Mars
   
4. Exit the Registry editor.
   
5. Restart the NetIQ services, NetIQ AppManager Client Resource Monitor and NetIQ Client Communication Manager.

The Management Server has two network interface cards installed, each with their own IP address. The Agent machine is picking up the wrong IP address when authenticating with the 'AllowMS' setting.
