(http://support.microsoft.com/kb/256986/ )Description of the Microsoft Windows registry
You use Windows Home Server to back up a computer. Then, you try to restore files from a backup file. When you select a backup file by using the Windows Home Server Console, and then you click Open, the Opening Backup dialog box appears as expected. However, when the Opening backup progress indicator reaches approximately three percent, you receive the following error message:
You experience this problem even if you are a member of the Administrators group on the local computer.
Cannot connect to the backup service on the server. Verify that all services are running.
Note If you log on as a different administrator, the backup file opens successfully.
This problem occurs if the following conditions are true:
This private key is installed by using the default permissions and the default owner. The default owner of this key is not the Administrators group. Instead, the default owner of this key is the administrator who installs Windows Home Server Connector. Therefore, if more than one administrator is configured on the computer, only the administrator who installed Windows Home Server Connector can access the key. By default, no other administrator can access the key.
The private key is required to start the restore operation from Windows Home Server. Therefore, only the administrator who installed Windows Home Server Connector can open the backup file.
Note Although this problem occurs on client computers that are running Windows XP, you might also experience this problem on a Windows Vista-based computer that has more than one administrator. For example, this problem may occur on a Windows Vista-based computer if a third-party program has damaged the folder that contains the private key.
Important These steps may increase your security risk. These steps may also make the computer or the network more vulnerable to attack by malicious users or by malicious software such as viruses. We recommend the process that this article describes to enable programs to operate as they are designed to or to implement specific program capabilities. Before you make these changes, we recommend that you evaluate the risks that are associated with implementing this process in your particular environment. If you decide to implement this process, take any appropriate additional steps to help protect the system. We recommend that you use this process only if you really require this process.
To resolve this problem, use one of the following methods:
To manually set permissions on the private keysUse the CACLS command to grant all administrators Full Control access to all computer-level keys.
Note Any administrator can take ownership of the keys. Therefore, this action does not significantly reduce security although this action gives all administrators complete access to the computer-level keys.
Important To modify the permissions of these keys, you must be logged on to the computer by using the account of the administrator who installed Windows Home Server Connector.
To grant all administrators Full Control access to all computer-level keys, follow these steps:
To turn off the policy that restricts access to the keys
Method 1: All versions of Windows XPWarning Serious problems might occur if you modify the registry incorrectly by using Registry Editor or by using another method. These problems might require that you reinstall the operating system. Microsoft cannot guarantee that these problems can be solved. Modify the registry at your own risk.
Method 2: Versions of Windows XP other than Windows XP Home Edition
