Unable to close MMC – You must close all dialog boxes before you can close


Long time no see y’all – been a bit quiet but am back with another bug from Microsoft;

When attempting to close MMC (Active Directory Users and Computers or the Exchange Management Console for example) on a Windows 2008 R2 server with Internet Explorer 9 installed you get the following error;

For the sake of our friend Google (as I’m not using my normal software to fill out the “blanks”) – thats “You must close all dialog boxes before you can close Exchange Management Console”

 

There is an interesting thread on the Technet forums that has been going some time;

It looks to affect Windows 7 also – so it must be the “7” suite of OS’s (i.e Windows 6.1).

 

The “work-around” at this moment is to uninstall IE9 – which is fine on your server (and not so fine on your Desktop). Some users have reported that disabling Enhanced Security for IE is a temporary fix (along with adding http://localhost and https://localhost to the Trusted sites), though I don’t see how this would work with Windows 7.

 

Official line from MS at this moment is “Sorry, we are working on it”.

 

Funnily enough it only seems to happen when certain dialog boxes / panes are opened (see above Technet post) – so if you do get it just kil mmc.exe from the Task Manager 🙂

 

Au Revoir!

    Hi,

    Another workaround: Create a new MMC with Exchange snap-in. Save it… and thats all.

      Interesting that this works – does it work for the other “buggy” MMC’s (like AD Users + Computers)?
