VSS2005忘记管理员密码解决方法

用UltraEdit打开data\um.dat，切换到十六进制编辑，修改00000080h到000000a0h这三行内容，例如原先为：

00000080h: 55 55 03 29 41 64 6D 69 6E 00 00 00 00 00 00 00
00000090h: 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00
000000a0h: 00 00 00 00 56 6B 00 00 A8 01 00 00 00 00 00 00

替换为：

00000080h: 55 55 BC 7F 41 64 6D 69 6E 00 00 00 00 00 00 00
00000090h: 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00
000000a0h: 00 00 00 00 90 6E 00 00 A8 01 00 00 00 00 00 00

修改后Admin密码重置为空，直接点"OK"按钮即可登录。
