Microsoft have released it’s second Update Rollup for Windows Home Server 2011. This update fixes 15 issues as listed below and should be available via Windows Update now. This release also addresses many of the issues with using WHS 2011 with Mac Lion.

Major issues that are resolved by this update

Issue 1

The network monitor service or the health service crashes occasionally. This issue causes the dashboard to also crash in the configuration router wizard. Additionally, an event that resembles the following is logged in the Application log:
Log Name: Application
Source: .NET Runtime
Date: datetime
Event ID: 1026
Task Category: None
Level: Error
Keywords: Classic
User: N/A
Computer: computer name
Application: SharedServiceHost.exe
Framework Version: v4.0.30319
Description: The process was terminated due to an unhandled exception.
Exception Info: System.InvalidOperationException
at System.Xml.Serialization.XmlSerializer.Deserialize(System.Xml.XmlReader, System.String, System.Xml.Serialization.XmlDeserializationEvents)
at Microsoft.WindowsServerSolutions.TaskManagement.Data.EngineStateFile.Load(System.String)
at Microsoft.WindowsServerSolutions.TaskManagement.TaskScheduler.ReadRestartState()
at Microsoft.WindowsServerSolutions.TaskManagement.TaskScheduler.RunTasks(System.String, System.String)
at Microsoft.WindowsServerSolutions.Networking.NetworkingMonitor.RepairRouter()
at System.Threading.ExecutionContext.runTryCode(System.Object)
at System.Runtime.CompilerServices.RuntimeHelpers.ExecuteCodeWithGuaranteedCleanup(TryCode, CleanupCode, System.Object)
at System.Threading.ExecutionContext.Run(System.Threading.ExecutionContext, System.Threading.ContextCallback, System.Object, Boolean)
at System.Threading.ExecutionContext.Run(System.Threading.ExecutionContext, System.Threading.ContextCallback, System.Object)
at System.Threading.ThreadHelper.ThreadStart()

This issue occurs because the operating system uses the same state file for different task lists that are running in parallel.

Issue 2

Music file tags are overwritten in a default share (\\server\music) that has remote access enabled. Additionally, the album art file is replaced by using a low-resolution hidden system file.

Issue 3

When a web browser control add-in is installed, and you try to close the Dashboard, an empty confirmation dialog box appears. This issue occurs if Internet Explorer 9 is installed.

Issue 4

Remote access permission restrictions do not apply to the Media Library. For example, when you grant a new user account permission to access the Music folder only, the new user can access the Picture and Video folders in Media Library by using a remote desktop session.

Issue 5

The Remote Web Access website (RWA) does not work correctly when you log on from a tablet device. For example, you cannot download files from the RWA website to a Google Android-based device, and you cannot upload files from an Apple IOS-based device to the RWA website.

Issue 6

The software name of the embedded Launchpad is the same for Mac Lion as it is for Windows. Therefore, the operating system assumes that the embedded Launchpad for Mac Lion is already installed. Because of this issue, you cannot install the connector on a Mac Lion-based client computer.

Issue 7

When you install a third-party application that uses the same altitude value as the Backupreader.sys, and then you try to restore the client backup, the restore process fails.

Issue 8

Assume that you try to perform a client backup. In this situation, the backup operation fails. Additionally, you receive the following error message:

Insufficient storage available for backup

This issue occurs because a hidden “Drivers for Full System Restore” folder is created on all the volumes that are included in the backup. If the client computer is running Windows 7, there is a hidden System Reserved partition that is only 100 megabytes (MB). However, the “Drivers for Full System Restore” folder is larger than 100 MB. Therefore, this issue occurs. After you apply this update, the “Drivers for Full System Restore” folder is not created on volumes that are smaller than one gigabyte (GB) or on volumes that do not have a driver letter.

Issue 9

The default input language for the Spanish version of Windows Home Server 2011 is English. After you install this update, an alert is displayed that states that the default input language is changed to either English or Traditional Spanish.

Issue 10

If a certificate that has a blank common name (CN) is created in certain situations, the identity management service cannot be run.

Issue 11

When Update Rollup 1 for Windows Home Server 2011 is installed on the server that is running a localized version of Windows Home Server 2011, two sets of shortcuts for Launchpad and Dashboard are created. In this situation, the names of the shortcuts are displayed in English in one of the sets and in the local language in the other set.

Issue 12

This update fixes and updates links to documents that provide guidance for discovering and deploying add-ins and additional applications.

Issue 13

Sharedservicehost.exe throws exception errors when the health monitoring service and the client backup service are running. This issue occurs when Launchpad or Dashboard is disconnected from the Internet. This behavior causes some services, such as the health monitoring service, the backup service, or the identity management service, to crash.

Issue 14

The UI of the client connector is incompatible with the new version of Windows client.

Issue 15

Client computers disappear from the Dashboard if request IDs for certificates are not returned in a numeric sequence. This issue may also cause the server to disappear from the Dashboard.

Known issues

Issue 1

Assume that you install the Launchpad on a client computer before this update is applied on the server. In this situation, the connector on the client computer updates automatically. This behavior causes the notification tray to crash on some localized versions of Windows Home Server 2011, such as the Italian and Portuguese Brazilian versions. This issue occurs only after this update is applied.

Issue 2

You do not receive an alert that states that automatic software updates for Mac Lion are disabled.

Issue 3

You do not receive an alert that states that software updates for Mac Lion are available.

Issue 4

There are no time-outs when you try to update the health status after the network connection is disconnected in Mac Lion.

Thanks for the update Nigel. I am installing these updates now. Will let you know if I see anything goofy.

The only problem ( initially ) being seen is ” I can no longer see shared files in the “Remote Web Access: Shared Folders” window. The folders show up in the left-hand navigation pane, but there is nothing in the right-hand file/folder navigation pane at any level below the HOMESERVER level, not even folders. ”
If that is it, pretty good for a rollup. I mean, you would expect it would break something.

I installed this updates and I notice that the server was working non-stop. I check the processes and WmiPrvSE.exe was utilizing 30 to 40% of the CPU. I killed the process and you could literally hear the server stop working non-stop. Now.. i do not know what i Killed. so I need to research further. the only add-in i have is Wake on Lan free from AWIECO. I also installed the fix for the harddrive lights. I’ll post if I find anything knew. Does anyone had the same problem?

One more thing.. I had not updated the plu-in to the latest version. I did after i kill the process.

I am having the same problem with WmiPrvSE.exe (Network Service) eating all my CPU time.
It did not do it till today (2/29/12) after the .NET Framework update though. Not sure exactly what is causing it.

After posting this I restarted the Server and everything behave normally so I’m really not sure what happend. I hope i wont see this return. I haven’t seen if there were any updates yesterday so I might have to repeat the process. So far the Server has being acting normally after the restart.

Nigel February 16, 2012 at 1:30 pm

I’m not seeing any of those issues. All my shared folders show up fine and WmiPrvSE.exe is sitting at 0% CPU usage and doesn’t appear to have moved since the update was installed.

Hopefully these are just isolated instances.

Immediately after update I started to receive “Computer Monitoring Error’ on server itself, once every hour… So far I googled for solution, but apparently there is no simple explanation to this, though issue existed in previous builds too. Dissatisfied…
