RFC_ERROR_COMMUNICATION: Connect to message server failed



I created a logon group and am trying to connect to R/3 using this logon group. I got the following error message :

Could not connect to message server.

Error: partner not reached (host sapserver, service sapmsD11)

D11 - system Id and sapserver is the host name of R/3.

I am facing the above problem when i tried to add a new Group in the logon pad of any client machine. I entered the message server as sapserver and clicked "Generate List" . At that point of time i faced this problem.

Can the application host name and message server name can be same ? How to figure out the message server IP / name ? I tried using the transaction SMMS and the server name is sapserver_D11_01. Is this my message server name ?

I was able to connect to SAP from the front end that was installed on the R/3 server by saying message server as sapserver.

I added the service sapmsD11 in the services file of sap server as well as the client machines.
