ranking functions, but only with the PARTITION BY clause for aggregate functions . I hope that future versions of SQL Server will enhance the support for the OVER clause and provide a more complete implementation of the standard s feature set . Queries such as the one just shown have the potential to run substantially faster than any of the existing solutions . Better support for window specifications would also prevent developers from having to sacrifice performance if they require benefits specific to T-SQL solutions, such as dependency tracking .

To start a VM, you need to either set the VM to automatically start or use the Hyper-V Manager console to start the VM. Right-click the VM in the console and select Start from the menu. If you have the Virtual Machine Connection for that VM open, you can select Start from the Action menu. To stop a VM, you should shut down the operating system in the VM. You can initiate this from the Hyper-V Manager console or on the Virtual Machine Connection Action menu, if Integration Services are installed in the VM. You can also stop a VM by right-clicking the VM in the console and selecting Turn Off , but this can cause corruption issues for the VM s operating system and is not recommended when other alternatives are available. You can save a VM from the Hyper-V Manager console or the Virtual Machine Connection for that VM by selecting Save from the Action menu. This will save the current state of the VM to disk and is similar to hibernating a physical computer. It does release memory and resources back to the parent partition.

The Buffer Security Check Switch The run-time checks are very cool, but another switch that you should always turn on is /GS, the Buffer Security Check switch. Unlike the /RTCx switches, /GS should be turned on for both debug and release builds. The purpose of /GS is to monitor the return address for a function to see whether it's overwritten, which is a common technique used by viruses and Trojan horse programs to take over your application. /GS works by reserving space on the stack before the return address. At the function entry, the function prolog fills in that spot with a security cookie XOR'd with the return address. That security cookie is computed as part of the module load so it's unique to each module. When the function exits, a special function, _security_check_cookie, checks to see whether the value stored at the special spot is the same as it was when entering the function. If the values are different, the code pops up a message box and terminates the program. If you want to see the security code in action, read the source files SECCINIT.C, SECCOOK.C, and SECFAIL.C in the C run-time source code. As if the security-checking capability of the /GS switch weren't enough, the switch is also a wonderful debugging aid. Even though the /RTCx switches will track numerous errors, a random write to the return address will still sneak through. With the /GS, you get that checking in your debug builds as well. Of course, the Redmondtonians were thinking of us when they wrote the /GS switch, so you can replace the default message box function with your own handler by calling _set_security_error_handler. If you do whack the stack, your handler should call ExitProcess after logging the error. 662

The exchange in Figure 2-12 consists of the following parts: 1. After the computer starts it creates some preauthentication data, consisting of, among other things, a time stamp. This preauthentication data is encrypted using a key derived from the computer s password. It is then packaged in a KRB_AS_REQ (Kerberos Authentication Service Request) packet and sent to the Authentication Service (AS) which resides on the Key Distribution Center (KDC), which, as it turns out, is the DC. 2. The AS constructs a Ticket Granting Ticket (TGT) and creates a session key that the client can use to communicate with the Ticket Granting Service (TGS), which also resides on the DC in Windows. This key is denoted with Keyclient,TGS in Figure 2-12. It is transmitted to the client encrypted with the client s own public key. This message is sent back as the KRB_AS_REP.

The call to VolatileRead forces NewMail to be read at the point of the call and the reference really has to be copied to the temp variable now . Then, temp will be invoked only if it is not null . Unfortunately, it is impossible to write the code as shown because there isn t a generic overload of the VolatileRead method . However, there is a generic overload of Interlocked.CompareExchange, which you can use:

If this option is turned off, the snapshot isolation level is not allowed in the database and row versions are not recorded in tempdb for snapshot isolation purposes . To demonstrate working with the snapshot isolation level, run the following code from connection 1 (making sure you first set the database option just shown):
