When attempting to add or select a Sharepoint 2010 Foundation server farm to the backup selection list in Backup Exec 2010 R2, the error "None of the Web servers for the specified server farm could be accessed" is displayed. No Sharepoint resources are left available to select.

WRN: Assembly binding logging is turned OFF.
To enable assembly bind failure logging, set the registry value [HKLM\Software\Microsoft\Fusion!EnableLog] (DWORD) to 1.
Note: There is some performance penalty associated with assembly bind failure logging.
To turn this feature off, remove the registry value [HKLM\Software\Microsoft\Fusion!EnableLog].
It has been seen that having both Sharepoint 2010 Foundation and Search Server 2010 Express installed on the same server causes Backup Exec to incorrectly detect the installation as a full Sharepoint 2010 Portal. When enumerating for selections, we fail to get the required topology for the Sharepoint environment and cannot show the selections.
This issue has been resolved by Backup Exec 2010 R2 Hotfix 148347
