RTC V2 RC2 - Jazz Setup Error: The server is unreachable

After Installing "RTC V2.0 RC 2", DB2 V 9.5, WAS 6.1 - enabled with LDAP

Logged in with JazzAdmin Group User for completing server setup based on the installation document.

But in "Configure Database" step on Jazz setup Web console I am getting the below error message "The server is unreachable. Check network connectivity."
Can anyone you please let me know where I went wrong on the configuration... how to resolve this?

Please do following:

WebSphere Application Server configuration updates

The following steps are required to properly configure WebSphere Application Server in Rational Team Concert 2.0.

1. Ensure that the latest fix packs for WAS and WASDK are installed. If deploying in WAS 7.0, it is critical that at least WebSphere Application Server 7.0.0.3 is installed.
2. Remove the old custom JVM properties:
1. com.ibm.team.repository.provision.profile
2. com.ibm.team.server.configURL
3. log4j.configuration
3. Add the new custom JVM property JAZZ_HOME and set the value to:

file:////server/conf


4. Ensure that the WAS security setting "Use available authentication data when an unprotected URI is accessed" is checked. If you are using the WAS Integrated Solutions Console, you can do this by:
1. Navigating to Security -> Secure administration, applications, and infrastructure -> Web Security - General Settings.
2. Selecting the checkbox for "Use available authentication data when an unprotected URI is accessed".


It is working for me.

Thanks
