Problems access OpenManage on ESX 4.0 (not ESXi)

I ran across a script for installing OpenManage on ESX 4.0:

I’m pretty well versed in Linux, and everything installed without error. I also rebooted the server. I have Windows 7 workstation I installed OpenManage on, and when I open it and receive the Managed System Login, I enter the IP address of the ESX host, root as the username, and I’ve tried calvin and the ESX root password, as well as another ESX account, but I continue receiving “Login failed…. Connection timeout). I did a “netstat –at” on the server, and the server is listening on port 1311, the firewall is open, and I can telnet to port 1311 from the client.  I’ve searched Google as well as the Dell forums, but I’m not making any progress. I feel this there is an easy remedy, so can anyone point me in the right direction? 

Thank you.
