I have created some groups, and then wanted to add some servers to these groups. Most of them I had no problem adding, but some groups I get this error:

I dont really know what is causing this.

For some groups I tried renaming them, and suddenly I could add the servers, but for others this solution doesnt work

Does the account used for discovery have appropriate permissions on the target computer?


Open a command window with the "Run As" option using the account used for discovery, normally this is the MOM server action account.  
Use the command "net view ComputerName to verify that the account can connect using the API NetworkStationGetInfo.  This command may return the result, "There are no entries in the list."  This simply means that, the machine does not have any publicly visible shares.  
If the result is "Access denied.", then the account used does not have permission to contact the machine.
If the result is The command completed successfully. then the computer is properly configured for discovery.
