Consider the following scenario:
- You enable the Unified Extensible Firmware Interface (UEFI) mode on a computer that is running Windows Small Business Server 2011 Standard.
- You configure a recurring backup task on the computer.
- You try to perform a bare-metal recovery by using the Recovery Console.
In this scenario, bare metal recovery does not find any valid backups.
Notes- This update does not change any existing backups on the computer. Therefore, you must configure the backup task again after you install this update.
- This issue only occurs in Windows Small Business Server 2011 Standard that was installed in UEFI mode.
Issue 2
Assume that you try to log on to the Remote Web Access webpage of Windows Small Business Server 2011 Standard by using a user principal name (UPN). In this situation, you receive the following error message:
Server Error in '/Remote' Application.
The domain is null or empty
Parameter name: domain
Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.
Exception Details: System.ArgumentException: The domain is null or empty
Parameter name: domain
Issue 3
Assume that you try to connect to a client computer that is joined to a Windows Small Business Server 2011 Standard-based network domain by using the Remote Web Access webpage. However, if your user name contains Unicode characters, the user name is displayed incorrectly when you are prompted to enter your credentials. For example, this issue occurs if your username contains a Chinese character.
Issue 4
You cannot download files from the Remote Web Access webpage if you log on to the webpage by using a slate device. For example, you cannot download files from the Remote Web Access webpage to an Apple iPad.
Issue 5
Assume that you migrate from Windows Small Business Server 2003 Standard to Windows Small Business Server 2011 Standard. In this situation, you cannot log on to the Remote Web Access webpage by using a nonadministrator account. When this issue occurs, you receive the following error message:
Server Error in '/Remote' Application.
An error (87) occurred while enumerating the groups. The group's SID could not be resolved.
Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.
Exception Details: System.DirectoryServices.AccountManagement.PrincipalOperationException: An error (87) occurred while enumerating the groups. The group's SID could not be resolved.
Note This issue does not occur every time that you perform a migration. This issue is caused by specific configuration settings (for example, unresolved security identifiers in a specific security group) on the source server.
Issue 6
After Small Business Server 2011 Standard has been updated with Update Rollup 2, some users may not be able to log on to the Remote Web Access with the following error:
Remote Web Access is not allowed for your user account. Contact the person who manages your server.
