MMC.exe crash on Windows Server 2012

    Question

  • Hi,

    I am trying to add a custom attribute in Active Directory. I followed the steps mentioned on TechNet:

    https://social.technet.microsoft.com/wiki/contents/articles/20319.how-to-create-a-custom-attribute-in-active-directory.aspx

    I was able to create the attribute and then add this attribute to User class. But while adding this attribute to user class, I got an error.

    MMC has detected an error in a snap-in. It is recommended that you shut down and restart MMC.

    After this error I am experiencing MMC crash every time click on Apply button whenI try to add attribute to user class. Please help me in resolving this error.


    Thanks and Regards,

    Nitin Manware

  • Hi,

    According to my research, the console may crash and usually this occurs when you do not save it. If you re-open the console the change should be present.

    Besides, please make sure your Server is up-to-date.

    If the issue persists, please help to collect some screenshots about the error.

  • Hi Alvin,

    I saved and reopened the console. Still the crash occurs. What I did is:

    In MMC, I added "Active Directory Schema" snap in. I went to "Classes". Opened properties of  "user" class. Now when I click on Apply it shows error "MMC has detected an error in a snap-in. It is recommended that you shut down and restart MMC. After this when I click on OK button MMC crashes.

    Thanks,

    Nitin
