0. Read, please read JDBC programming 101, before asking questions about JDBC programming with M$ SQL Server.

1. use jTDS if possible http://jtds.sf.net
http://www.cjsdn.net/post/view?bid=10&id=162184

1a. Consider not to use the 3 M$ JDBC jars at its C:\Program Files\... folder, but from somewhere with a straight-forward folder name (i.e. shorter and without spaces).

2. Install M$ SQL Server SP3a, not SP3.
(I have no experience with M$ SQL Server 2000 SP4)

2a. Consider changing to another port other than the default one, 1433.

3. Error establishing socket & issues with Windows XP SP2
Here're the official responses from M$ :

我安装的MSSQL 2000 个人版,操作系统是XPSP2.安装MS SQL 2000 采用默认路径. 如果JDBC在连接时如果出现 NO SUITABLE DRIVER
就将Microsoft SQL Server 2000 Driver for JDBC SP3安装上.将你安装文件夹LIB下的msbase.jar,mssqlserver.jar,msutil.jar三个文件加到类路径中即将CLASSPATH设置为
C:\Program Files\Microsoft SQL Server 2000 Driver for JDBC\lib\msbase.jar;C:\Program Files\Microsoft SQL Server 2000 Driver for JDBC\lib\mssqlserver.jar;C:\Program Files\Microsoft SQL Server 2000 Driver for JDBC\lib\msutil.jar;E:\java\bao\*.*;我的安装都是默认安装所以路径有点长啊.
如果还出现 Error establishing socket异常,那么就安装MS SQL SERVER2000的补丁.我建议最好安装sql server pack sp3,SP4可能i不行.安装的文件名是chs_sql2ksp3.exe.安装后就可以用了,如果你是使用JCRETOR编辑器编辑的话运行还是会出现如下错误:
java.lang.ClassNotFoundException: com.microsoft.jdbc.sqlserver.SQLServerDriver
at java.net.URLClassLoader$1.run(URLClassLoader.java:198)
at java.security.AccessController.doPrivileged(Native Method)
at java.net.URLClassLoader.findClass(URLClassLoader.java:186)
at java.lang.ClassLoader.loadClass(ClassLoader.java:299)
at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:265)
at java.lang.ClassLoader.loadClass(ClassLoader.java:255)
at java.lang.ClassLoader.loadClassInternal(ClassLoader.java:315)
at java.lang.Class.forName0(Native Method)
at java.lang.Class.forName(Class.java:140)
at a.main(a.java:8)
但是如果在CMD(命令行方式运行时)将会显示:
E:\java>java a
regeister driver success
[Microsoft][SQLServer 2000 Driver for JDBC]Database changed to student
[Microsoft][SQLServer 2000 Driver for JDBC][SQLServer]已将数据库上下文改为 'stud
ent'。
[Microsoft][SQLServer 2000 Driver for JDBC]Language changed to 简体中文
[Microsoft][SQLServer 2000 Driver for JDBC][SQLServer]已将语言设置改为简体中文
。
1 98.0
5 98.0
5 90.0
1 12.0
恭喜你,成功了.

You could move the 3 jars to another folder with a shorter path.
E:\java\bao\*.* ?? Are you sure this works?

You may want to show us the source code of a.java (BTW, bad class name).
I'm wondering whether this is a question.

Does JCreator (not JCRETOR, I suppose) us system's CLASSPATH automatically? I think you should set it properly in JCreator.
