Not sure may be I didn't read the installation guide correctly.
First I get a failure unable to create repository due to DB (AD account) password is too complex due SQL 2008 denied account to create repository on vcenterdb database instance.
Second error, I get unable linked two systems. Not sure if there were specific firewall port I need to request the firewall team to open across the WAN.
I think I had spent at least 4 hours figuring out the 1st error - unable to create a repository via good search...
Any suggestion would help.
