当你点击计算机右键“管理”时，找不到文件，说明你的电脑中毒了。我的电脑就昨天因为插了优盘中毒了，杀完之后，今天用的时候发现就出这个问题了，查找了一下，所有的文件都在，但是关联性却没了，废话少说，自己看吧。

Windows: All .msc file can't open, access is denied (控制台文件拒绝访问)

Issue Description：

Terminal Server can't connect from clients.

Our Server found  a virus named W32.SillyFDC. We used Symantec kill it.

Then we found all .msc file can't be open.

 

Check:

As you known, .msc is linked to .dll, .exe and so on. And we run .exe file and it's OK. But .dll must use .msc to open.

So we think its problem is on .msc.

In safe mode, check and scan system driver, no found

Solution:

1, Check regedit information. Can't be solved

2, regsvr32 C:\Windows\system32\msxml3.dll (.msc need it to explan). Can't be solved

3, Copy a .msc from another server to TS and it still can't run. Can't be solved

4, Try to register some .dll file referred .msc. Can't be solved

5, mmc.exe %windir%\system32\eventvwr.msc. EventViewer can run.

It's meanings the issue is referred open with(open way). It need mmc.exe to open the .msc program.

OK, when you move your mouse on a link such as Admin Tools->IIS Right click, select open with->always use selected program and browse-> find C:\windows\system32\mmc.exe file. Selected it and OK.

Then you'll find all .msc can be open.

说白了就是，你找到一个msc文件，然后双击，会让你选择打开方式，你找到它C:\windows\system32\mmc.exe file. 用它打开就好了。
