Symptoms
You can use the SHUTDOWN method for the SQL Distributed Management Objects (SQL-DMO) server object to shut down the SQL Server service. The following message is sent back to SQL-DMO from the SQL Server server:
Server shut down by request.
SQL Server is terminating this processSQL-DMO treats this as an error condition. However, SQL-DMO should not treat this as an error condition because shutting down SQL Server is the expected result. If you do not handle this error condition in the Microsoft Visual Basic application, the standard error message dialog box opens. After you acknowledge the error message, the application terminates immediately, which may not be behavior you expect and may also produce unfavorable results.
Another error message that might occur is:
Error number: -2147215802
Error source: Microsoft SQL-DMO (ODBC SQLState: 01000)
Resolution
By adhering to good programming practices and making sure that error conditions are handled within the Visual Basic code, you can prevent the unexpected termination of the application. Additionally, even after the error condition is handled, the SQL-DMO SQL Server object is still connected to the SQL Server server that shut down. Thus, it is necessary to run the Disconnect method if you want to reuse the object. If you do not need the object, to release the object you can set the object to Nothing.
Here is an example:
On Error GoTo errHandlerSet oSQLServer = New SQLDMO.SQLServeroSQLServer.LoginSecure = TrueoSQLServer.Connect’ Need to connect to SQL Server firstoSQLServer.Shutdown’ Execute shutdownoSQLServer.DisConnect’ Disconnect from SQL Server if object is to be reused:’ Rest of code. Without error handling, application will not get here:Set oSQLServer = Nothing’DoneerrHandler::’ Error handler

Symptoms
When you perform stress tests on a Windows Server 2008 system that has the Hyper-V role installed, the system may stop responding or hang.
Resolution
A thread on one processorowns a network device interface specification (NDIS) Read lock or Write lock. This thread waits for a spinlock. However,a thread on a second processor owns the spinlock, and this threadwaits for the same NDIS Read lock or Write lock that is owned by thethread on the first processor. This creates a deadlock situation. Therefore the computer stops responding.

Symptoms
In some cases, collections defined at a parent site do not appear in the collection hierarchy of a child site. A symptom of this problem is the generation of status message “2528.” This status message defines which collection (or subcollection) is causing the problem. After the collection has been identified, you may find that one or more of the .psd files, which are pending in the SMS\INBOXES\Colleval.box file for the collection, are experiencing problems.
Resolution
This problem typically occurs when defining a subcollection. When you add this new subcollection, the parent collection (including the new subcollection) must be copied down to the child site. This is because the addition of a subcollection is considered a change to the parent collection.
When the collections are received at the child site, the new subcollection is saved, but the parent is not. The parent site then checks to make sure that each of its children exist in the database. Child sites that do not exist in the database are placed back in the queue for reprocessing at a later time.
