svchost.exe 100% CPU usage

XP prof sp2 For past 2 days, my PC starts freezing after logging in. I have noticed svchost.exe corresponding to a larger set of services (AudioSrv, ... winmgmt, wuauserv) using up 100% cpu. After killing svchost.exe, everything comes to normal, but without those services - which is not recommended as you will lose all the features such as network, audio, etc After googling, I came across a suggestion on removing c:\windows\softwaredistribution folder (maybe wuauserv is going crazy). After removing the folder, pc starts up normally.

• The workaround is to remove the c:\windows\softwaredistribution folder and restart the pc

WS Enhancements & WS-*

The Web Services Enhancements (WSE) is a .NET class library that augments the .NET Framework and related technologies to provide an implementation of various WS-* specifications. If you look across the WS-* specifications you see a trend where functionality is being elevated from the transport protocol level (security, reliability, session management) to the message protocol level (WS-Security, WS-ReliableMessaging, WS-SecureConversation) and when combined with agreed specifications for data exchange (XML, XML Schema, SOAP, WSDL) and existing transport protocols (HTTP, TCP, UDP) this enables adaptable and extensible applications that also deliver on the goals on interoperability and integration.

Eval Vs Bind

use of two distinct operators for binding: Eval and Bind. Eval is an operator you use in data-binding expressions to access a public property on the bound data item. Functionally speaking, it is nearly equivalent to the DataBinder.Eval method you would have used in ASP.NET 1.x in the same situation. As used in the preceding code, Eval is an ASP.NET 2.0-only feature and will generate a compile error if used in an ASP.NET 1.x application. Furthermore, it will throw an exception if used in an ASP.NET 2.0 page outside of a template. The Bind operator is like Eval, except that it adds the ability to write data back to the original data source field. In the previous code snippet, notice that at display time the Bind operator sets the SelectedValue property of the DropDownList control with the value of the country field from the data source. So, how are values passed back to the control for updating the data source?
