RPC implements a series of tasks in order to establish communication between a client and a server. First, the client initiates a specific objective by contacting a local process known as a “client stub” with parameters for accessing a file or service. The client stub converts the parameters it receives from the client into appropriate parameters on the server. The client stub then sends these new parameters to the operating system’s kernel, which then sends the message to the server stub (same as client stub, but is located on the server machine). The server stub decodes the message and sends it to the appropriate application or service. Once the application has been contacted, replies may be sent in the reverse direction through each of these processes.

Click Start. Right-click Computer, and then click Properties. 2. Click Advanced System Settings. 3. On the Advanced tab, under Startup and Recovery, click Settings. 4. Click the Default Operating System list, and edit other startup settings. Then, click OK. Same as Windows XP, right? But you’re probably not here because you couldn’t find that dialog box. You’re probably here because Windows Vista won’t start. In that case, you shouldn’t even worry about editing the BCD. Just run Startup Repair, and let the tool do what it’s supposed to. If you’re an advanced user, like an IT guy, you might want to edit the BCD file yourself. You can do this
