'No such host is known' error when configuring Reporting database

Question

Hi,
We are joining two report server databases using reporting services config manager. The problem is when we are trying to connect database on another machine we are receiving following error at step 'generating Rights script'
System.Net.Sockets.SocketException: No such host is known
   at System.Net.Dns.GetAddrInfo(String name)
   at System.Net.Dns.InternalGetHostByName(String hostName, Boolean includeIPv6)
   at System.Net.Dns.GetHostEntry(String hostNameOrAddress)
   at ReportServicesConfigUI.RSDatabase.IsLocalDbServer(String dbServer)
   at ReportServicesConfigUI.RSDatabase.GrantRSConnectionRights()
   at ReportServicesConfigUI.RSDatabase.CreateNewDatabase()
As per step mentioned in following link,
http://blogs.msdn.com/b/sameersurve/archive/2009/06/15/no-such-host-is-known-error-when-configuring-ssrs-2008.aspx
We tried opening port 1434 for the Reportserver db machine. but it didnt worked for me.
Following are points i feel could be the reason of failure,
1. The two machine we are working on are in different domains.
2. The Product version of the two reporting servers are different.
Have anyone experienced this if yes any solution that i can try?

Hi Shrikant_k,
If we are using a remote database server for the report server database, we should refer to the following tips:
Enable remote connections. And we should also open your firewall software and open the port that SQL Server listens on. For the default instance, this is typically port 1433 for TCP/IP connections. To verify that the instance accepts remote connections,
please refer to the following article:
http://technet.microsoft.com/en-us/library/ms157300(v=sql.105).aspx
When you enable remote connections, the client and server protocols will also be enabled. To verify the protocols are enabled, please see:
http://technet.microsoft.com/en-us/library/ms191294(v=sql.105).aspx
When the database server is in a different domain or we are using workgroup security, we must configure the connection to use a SQL Server database login. In this way, we must update the report server database connection every time we change the password
or the account.
When creating a report server database, be aware that not all editions of SQL Server can be used to host the database. The following document is for your reference:
http://technet.microsoft.com/en-us/library/ms157285(v=sql.105).aspx

Hope this helps.
