Powerpath viewer Mangement comp only works on win2k3

Hello all,

I have the Powerpath viewer running and I have been installing the mangement component on all of my servers. So far, the viewer can only connect to the clients running the management component  5.3 P01. I can't connect to a client running mangement Component 5.5 P01

Client

Enable = Yes

Port = 9083

Heartbeat = 15 min

Single Path Gatekeepers = ok (disable warnings)

Server is 1.0.SP1 b032

Thanks
