最简答的方法就是重启下
mysqld-nt --skip-grant-tables 重置密码后要结束MYSQL进程，重新启动MYSQL。
我去查了端口占用，里面没有3306被占用
回复2楼
在复置密码后我去进程管理器结束了mysqld-nt.exe 然后重启完就再也启动不了mysql 了
服务器上上就一个mysql，稳定运行一年多了，由于要加新东西，我忘密码后，重置后就出现这个问题了
刚重启完服务器，还是不行
以下附上一些参考内容 C:\Documents and Settings\Administrator>mysql
ERROR 2003 (HY000): Can't connect to MySQL server on 'localhost' (10061)C:\Documents and Settings\Administrator>net start mysql
发生系统错误 193。*** 不是有效的 Win32 应用程序。
从提示上看
121206 15:02:09 [Note] mysqld-nt: ready for connections.
已经启动MYSQL了
第二遍重启服务器后， 把.err 文件还原，删除里面所有内容 再重启mysql 问题依旧，.err内容 为空
第三遍重复第二遍....
MySQL 不是有效的 Win32 应用程序。
C:\pro....saasafa\mysql\mysql-5.1.58-win32\bin\mysqld --console然后看输出的内容是什么。如果异常则贴出显示。

说明已经启动了MYSQL，检查一下MI。INI中DATADIR，看看目录中是否有
数据文件
以下显示my.ini的截图
输入启动进入mysql 显示如下
C:\Documents and Settings\Administrator>mysql -n root -p
Enter password: *******
ERROR 2003 (HY000): Can't connect to MySQL server on 'localhost' (10061)
另外打开一个命令行窗口，执行mysql
>use mysql
>update user set password=password("new_password") where user="root";
>flush privileges;
>exit
用Ctrl+Alt+Del，找到mysqld-nt的进程杀掉它，在重新启动mysql-nt服务，就可以用新密码登录了
我就是按上述方法重置的密码， 完全遵照执行的。 在我结束mysql-nt服务后，然后重启利用net start mysql 后则提示错误193，再就无法启动mysql-nt这个服务了， 然后就出现了我1楼问题的问题了
现在用net start mysql 启动时，提示错误193
用服务窗口启动时也是提示错误193.
就是无法启动服务。
直接输入启动进入mysql 显示如下
C:\Documents and Settings\Administrator>mysql -n root -p
Enter password: *******

使用mysqld-nt --console后提示以上，这时mysql启动成功，数据访问正常。进程中也有mysqld-nt.exe但是一旦把这个CMD窗口关掉，mysqld-nt就会随之自动关掉了。 这可怎么处理啊。
试试，估计是MYSQL的服务被破坏了
C:\Program Files\MySQL\MySQL Server 5.0\bin>mysqld-nt -install
The service already exists!
The current server installed: "C:\Program Files\MySQL\MySQL Server 5.0\bin\mysql
d-nt" --defaults-file="C:\Program Files\MySQL\MySQL Server 5.0\my.ini" MySQL
按以上步骤，当出现mysqld-nt.exe后，杀掉，然后利用mysqld-nt --install 后，提示如下
C:\Program Files\MySQL\MySQL Server 5.0\bin>mysqld-nt -install The service already exists! The current server installed: "C:\Program Files\MySQL\MySQL Server 5.0\bin\mysql d-nt" --defaults-file="C:\Program Files\MySQL\MySQL Server 5.0\my.ini" MySQL然后去管理中的服务中，去启动mysql服务 ，提示依旧是错误193. 现在唯一可以做的就是 打开cmd窗口，输入mysqld-nt --console 一直开着这个窗口，这样服务器用到mysql的网站才能全部运行，否则全都提示无法连接到数据库
但是这样也不是个办法啊
sc delete mysql服务名
再mysqld-nt -install
运行结果如下：
C:\Documents and Settings\Administrator>sc delete mysql
[SC] DeleteService 成功C:\Documents and Settings\Administrator>mysqld-nt -install
Service successfully installed.C:\Documents and Settings\Administrator>mysql
ERROR 2003 (HY000): Can't connect to MySQL server on 'localhost' (10061)C:\Documents and Settings\Administrator>
再mydqld-nt -install 成功
然后服务项中出来mysql了，点击启动。提示193错误....重试了两遍，重启了服务器，还是以上的错误
发生系统错误 193。*** 不是有效的 Win32 应用程序。
C:\Documents and Settings\Administrator>
发生系统错误 193。*** 不是有效的 Win32 应用程序。
C:\Program Files\MySQL\MySQL Server 5.0\bin>my.ini 有过修改，是利用MySQLInstanceConfig.exe 进行过修复，不过修复到最后也是卡在了不能启动服务上了就过不去了。
后来我又把my.ini 重新恢复了。

# ----------------------------------------------------------------------
# Generated by the MySQL Server Instance Configuration Wizard
#
#
# Installation Instructions
# ----------------------------------------------------------------------
#
# On Linux you can copy this file to /etc/my.cnf to set global options,
# mysql-data-dir/my.cnf to set server-specific options
# (@localstatedir@ for this installation) or to
# ~/.my.cnf to set user-specific options.
#
# On Windows you should keep this file in the installation directory
# of your server (e.g. C:\Program Files\MySQL\MySQL Server X.Y). To
# make sure the server reads the config file use the startup option
# "--defaults-file".
#
# To run run the server from the command line, execute this in a
# command line shell, e.g.
# mysqld --defaults-file="C:\Program Files\MySQL\MySQL Server X.Y\my.ini"
#
# To install the server as a Windows service manually, execute this in a
# command line shell, e.g.
# mysqld --install MySQLXY --defaults-file="C:\Program Files\MySQL\MySQL Server X.Y\my.ini"
#
# And then execute this in a command line shell to start the server, e.g.
# net start MySQLXY
#
#
# Guildlines for editing this file
# ----------------------------------------------------------------------
#
# In this file, you can use all long options that the program supports.
# If you want to know the options a program supports, start the program
# with the "--help" option.
#
# More detailed information about the individual options can also be
# found in the manual.

# CLIENT SECTION
# ----------------------------------------------------------------------
#
# The following options will be read by MySQL client applications.
