XADM: MMC Does Not Run after Microsoft Exchange Chat Service 5.5. SP1 is Installed on a Backup Domain ControllerID: Q184731
|
After you install the Microsoft Exchange Chat Service 5.5 Service Pack 1 or Microsoft Commercial Internet System Chat 2.0 on a Backup Domain Controller (BDC), the Microsoft Management Console (MMC) is does not run. The following error message appears:
An application error has occurred and an application error log is being generated
mmc.exe
Exception access violation (0xc000005) Address 0x10021433
This error occurs because the Chat Administrator Account is not created as a local account on the Backup Domain Controller.
WARNING: Using Registry Editor incorrectly can cause serious problems that
may require you to reinstall your operating system. Microsoft cannot
guarantee that problems resulting from the incorrect use of Registry Editor
can be solved. Use Registry Editor at your own risk.
For information about how to edit the registry, view the "Changing Keys And
Values" Help topic in Registry Editor (Regedit.exe) or the "Add and Delete
Information in the Registry" and "Edit Registry Data" Help topics in
Regedt32.exe. Note that you should back up the registry before you edit it.
If you are running Windows NT, you should also update your Emergency
Repair Disk (ERD).
To correct this problem, export and then merge the Chat Administrator Key
from a Primary Domain Controller (PDC) or Member Server to the BDC. To
export the key, perform the following steps:
HKEY_LOCAL_MACHINE\Software\Microsoft\Exchange\ChatSvc
\Parameters\Accounts
To work around this problem, install the registry key (see the Resolution section above), and then install the Microsoft Exchange Chat Service. The MMC functions properly after these steps have been completed.
Microsoft has confirmed this to be a problem in the Microsoft products listed at the beginning of this article.
This is not a problem when the Microsoft Exchange Chat Service is installed on a Primary Domain Controller or a Member Server.
