Example problem 3: Automated System Recovery (ASR) through Asr_pfu.exe file [More detailed Link]. This behavior occurs if one of the following conditions is true:

• You use backup media from the release version of Windows Server 2003.
• You use this backup media to restore a computer that has a service pack installed.

You use backup media from a version of Windows Server 2003 that has a service pack installed. You use this backup media to restore a computer that is running the release version of Windows Server 2003.

Solution: To work around this behavior, restore the computer by using a backup set that has the same service-pack level as the computer. For example, to restore a computer that is running the release version of Windows Server 2003, use a backup set that contains the release version of Windows Server 2003.

To restore a computer that is running Windows Server 2003 Service Pack 1 (SP1), use a backup set that contains Windows Server 2003 SP1.
