Error message when you back up a Windows Server 2003-based virtual machine on a Windows Server 2008 Hyper-V-based computer: “GetWriterStatus FAILED for Selected writer [Microsoft Hyper-V VSS Writ …

Symptoms
Consider the following scenario:You run a Windows Server 2003-based virtual machine on a Windows Server 2008 Hyper-V-based computer.The virtual machine has files that reside on the array disk volume.You try to back up the virtual machine by using Windows Server Backup.
Note Windows Server Backup uses the Microsoft Hyper-V VSS writer to create a hardware snapshot. In this scenario, the Hyper-V VSS writer crashes. Therefore, the snapshot is not created. Additionally, you may receive following error message:

GetWriterStatus FAILED for Selected writer [Microsoft Hyper-V VSS Writer], writer is in state [9] [VSS_WS_FAILED_AT_FREEZE]. hrWriterFailure [80042319] When this issue occurs, the following VSS error is logged in the Application log:
An unhandled exception was encountered while processing a VSS writer event callback. The VSS writer infrastructure is in an unstable state. The writer hosting process must be restarted in order to resume VSS functionality.

Information about lingering objects in a Windows Server Active Directory forest

Symptoms
This article contains information about lingering objects in ain a Microsoft Windows 2000-based forest or in a Windows Server 2003-based forest. Specifically, the article describes the events that indicate the presence of lingering objects, the causes of lingering objects, and the methods that you can use to remove lingering objects.
Resolution
Lingering objects can occur if a domain controller does not replicate for an interval of time that is longer than the tombstone lifetime (TSL). The domain controller then reconnects to the replication topology. Objects that are deleted from the Active Directory directory service when the domain controller is offline can remain on the domain controller as lingering objects. This article contains detailed information about the events that indicate the presence of lingering objects, the causes of lingering objects, and the methods that you can use to remove lingering objects.

Error message on a computer that is running Windows Vista Service Pack 1 or Windows Server 2008: “Stop 0×00000024″

Symptoms
On a computer that is running Windows Vista Service Pack 1 or Windows Server 2008, you may receive a Stop error message that resembles the following:

Stop 0×00000024 (parameter1, parameter2, parameter3, parameter4)NotesThe results of a Stop error message may vary, depending on the system failure settings of the computer.The parameter values may vary, depending on the computer configuration.Not all “STOP 0×00000024″ error messages are caused by the problem that is described in this article.
Resolution
When the NTFS.sys driver is updating a shared security descriptor, an exception may occur because of a disk error or because a log file is full. In this situation, the NTFS.sys driver may release a shared security descriptor structure prematurely. This behavior causes the NTFS.sys driver to access a freed shared security descriptor structure. Therefore, a Stop error is triggered.

LDAP queries are executed more slowly than expected in the AD or LDS/ADAM directory service and Event ID 1644 may be logged

Symptoms
On a Windows Server 2003-based or Windows Server 2008-based computer that uses an Active Directory Lightweight Directory Services (AD LDS) or Active Directory Application Mode (AD/AM) directory service, certain applications do not perform at the performance levels that are expected.
When you enable field engineering (debug) logging to trace an LDAP query, the following event log shows that the LDAP query is an inefficient query:
Event ID : 1644
Category : Field Engineering
Source : NTDS General
Type : Information
Machine : ComputerName
Message : Internal event: A client issued a search operation with the following options.
Client: 100.110.1.5
Starting node: DC=contoso,DC=com
Filter: (&(objectcategory=user)(gidnumber=29831))
Search scope: subtree Attribute selection: …
Server controls:
Visited entries: 31950
Returned entries: 1 Note The attributes that are used in this event are only examples.
Additionally, you experience a slow response time.
When you inspect the attributes in the search filter, you find that they all have indexes that are defined. Additionally, if attributes do not have indexes that are defined, and you add the indexes through a schema change, the problem persists.
Resolution
When you create a network trace of the LDAP query, you notice that it is a paged query.
However, the LDAP server can only use one index to process a paged query. This is because LDAP does not have a transaction to end a query, and the implementation for paged searches does not create an expensive context for the query.
