When migrating to Small Business Server 2011 Administrators may receive the following error message. 


Cannot find the Source Server

Verify that the Source Server name is correct, and then try again.





The problem is usually due a timing issue. The network card is provisioned with DNS servers right before a ping of the source server name is attempted, in some cases, the network card is not yet ready to handle this, when that is the case, an exception will happen and the error will be displayed.



The first thing you should do is acknowledge the error by pressing OK and then, wait at least 30 seconds, before clicking Next again to proceed.  If you receive the same error a second time then it is most likely NOT the issue described in this article, and further troubleshooting would be required to understand why the new server is failing to ping the source server.

To confirm you are experiencing this issue you can check the setup logs by doing the following steps:  


  1. Select <Shift + F10> to open a command prompt
  2. Navigate to the C:\Program files\Windows Small Business Server\Logs\ and open the SBSSetup.log using notepad.exe


Setup: Pinging old server name.

Setup: InvalidOperationException while pinging: System.Net.NetworkInformation.PingException: An exception occurred during a Ping request. ---> System.Net.Sockets.SocketException: The requested name is valid, but no data of the requested type was found

   at System.Net.Dns.InternalGetHostByName(String hostName, Boolean includeIPv6)

   at System.Net.Dns.GetHostAddresses(String hostNameOrAddress)

   at System.Net.NetworkInformation.Ping.Send(String hostNameOrAddress, Int32 timeout, Byte[] buffer, PingOptions options)

   --- End of inner exception stack trace ---

   at System.Net.NetworkInformation.Ping.Send(String hostNameOrAddress, Int32 timeout, Byte[] buffer, PingOptions options)

   at System.Net.NetworkInformation.Ping.Send(String hostNameOrAddress)

   at Microsoft.WindowsServerSolutions.Setup.SBSSetup.MigrationInformationPagePresenter.ValidateServerName(Boolean runCostlyValidation)


If you are not seeing this exception and still getting the same error, check the following:

To verify there are no name resolution problems with the network:

  1. Select <Shift + F10> to open a command prompt
  2. Ping the Source Server  Netbios Name   (i.e. SBS2003)
  3. Ping the Source Server Internal FQDN    (i.e. SBS2003.R2.local)


Note:  This error will also occur if there is a misspelling of the Source Server name or Internal Domain name.
