在Domain 2003环境下，客户端在使用“强制使用墙纸”策略后，有部分客户端XP在使用一段时间后，会出现“Active Desktop recovery”的错误，无法还原到正常的桌面环境，最后，在网上找到了答案：
修改注册表：
HKC U\Software\Microsoft\Internet Explorer\Desktop\SafeMode\Components
DeskHTMLVersion 的值改为 0 ，重启后即可！
附件中已经含有修正这个问题的文件*** ，另外 注意权限问题
PS:
此问题，还有一个解决的方法就是重建当前用户的配置文件，因为重建配置文件要花比较长的时间要重新配置个人环境，所以不太建议使用这个方法！

系统因为掉电重启后出现讨厌的Restore my Active Desktop. 点击以后竟然报错。Error：Object not support this action.
Google一番找到了答案！
If you have installed IE7 you are guaranteed to get a script error for this action.
The normal advice will not work if you are on a security enabled
windows 2003 domain . The only fix then is to perform a registry edit
for the individual user.
Run Regedit
Navigate to:
HKCU\Software\Microsoft\Internet Explorer\Desktop\SafeMode\Components
Change the DeskHTMLVersion key from 272 to 0 and reboot. The original desktop should now be back.
All we need now is for Microsoft to actually fix the issue as none
of this helps with a terminal server with full Group Policy
restrictions on running regedit as a user - 3 reboots are necessary to
fix the issue which is no use on a server used 24hrs a day by remote
users.
我不用重启直接就显示了active desktop.
