Not able to see any nodes in the management console

Hi,

I installed WAS 6.40 sp9 recently and on that I installed EP6 SP9.I even installed KMC and TREX .Every thing was done successfully.But now I just tried to restart the j2ee server.Through SAP MMC I want to start but to my surprise there are no nodes in that to start the server.Did any body encounter this problem?If so please help me to resolve this issue.

Or <b>Can any one tell me how to start the j2ee server with out using SAP MMC?</b>

Regards,

Santhosh
