这个问题我回答过多次了．
不是没有了，是没有注册到面版上而已．
下面是Delphi7的readme.txt文件的一段，自己看：
Borland is deprecating the use of the TServerSocket
and TClientSocket from the unit ScktComp. It is
recommended that you use the Indy components for
socket operations. The TServerSocket and
TClientSocket will no longer be installed on the
component palette by default. If you require the
use of these components then you can install
the design time package named dclsockets70.bpl,
found in your bin directory. For deployment with
runtime packages, you will need to deploy rtl70.bpl
and any other required packages.
