Having the same problem as SaranyaM. After vCenter (Simple) installation completes succesfully I can connect using vSphere client. But after first reboot the VirtualCenter service don't start and I cannot connect. I you SQL express and no AD. DNS A/PTR i ok..
================
In Event viewer I see error: 1000
In vpxd I see:
2013-01-22T15:34:47.124+01:00 [03020 error 'HttpConnectionPool-000001'] [ConnectComplete] Connect failed to <cs p:00000000082f0850, TCP:10.10.10.80:7444>; cnx: (null), error: class Vmacore::SystemException(No connection could be made because the target machine actively refused it. )
2013-01-22T15:34:47.124+01:00 [02816 error '[SSO][SsoCertificateManagerImpl]'] [CreateAdminSsoServiceContent] Failure while trying to connect to SSO Admin server: No connection could be made because the target machine actively refused it. . Will retry in 10 seconds.
==============
Dont want to fix with SaranyaM workaround if there are still bugs.
Could this be a microsoft patch. I did a windows update before installation.
