Not able to connect using SOAP with WAS 6.1 server

[Sagar Kar]

I was learning some was administration. So I downloaded the WAS 6.1 installables for windows and was trying to install on a XP development box.
However when I have the security settings on I am unable to stop the server or check the server status. I tried wsadmin and it also fails when using SOAP. Basically I am unable to connect to the server using SOAP protocol even though I am using the correct port and host.
I am able to connect wsadmin using RMI. The error I am getting is related to certificates. But I don't know how to fix it. I get some kind of SOAP Client error and it seems to be some kind of SSLHandshakeException.

com.ibm.websphere.management.exception.ConnectorException: ADMC0053E: The system cannot create a SOAP connector to connect to host <host name> at port 8884 with SOAP connector security enabled.
