Preparation

1. For successful installation on a remote machine running any Windows XP version, the option Control panel > Folder options > View > Use simple file sharing must be disabled on that machine.
2. For successful installation on a remote machine running Windows Vista or later, User Account Control (UAC) must be disabled. To access this option, go to Control panel > User Accounts > Change User Account Control Settings.
3. File and Printer Sharing must be enabled on the remote machine. To access this option:
   • On a machine running Windows XP with Service Pack 2 or Windows 2003 Server: go to Control panel > Windows Firewall > Exceptions > File and Printer Sharing.
   • On a machine running Windows Vista, Windows Server 2008, or Windows 7: go to Control panel > Windows Firewall > Network and Sharing Center > Change advanced sharing settings.
4. Acronis Backup & Recovery 11 uses TCP ports 445 and 25001 for remote installation. Make sure that these ports are added to exceptions in the firewall settings on the remote machines. TCP port 445 is added to exceptions automatically by Windows Firewall when you enable File and Printer Sharing.

   To add a port to exceptions:

   • In Windows XP and Windows Vista: go to Control panel > Windows Firewall > Exceptions > Add Port
   • In Windows 7: go to Control panel > Windows Firewall > Advanced settings > Inbound Rules > New Rule > Port

     Tip: If the remote machines are members of an Active Directory domain and use no firewall other than Windows Firewall, you can add TCP port 25001 to exceptions by using Group Policy. On a domain controller, create a Group Policy object, then go to Administrative Templates > Network > Network Connections > Windows Firewall > Domain Profile > Windows Firewall: Define port exceptions (or: Define inbound port exceptions), and then add the following port exception:
     25001:tcp:*:enabled:Acronis remote install

You can exclude both ports from exceptions after the remote installation is complete.
