| Description | Microsoft Exchange System Attendant failed to add the local computer as a member of the DS group object <name>. |
| Event Information | "According To Microsoft:" Explanation: This event indicates that the System Attendant has detected that the local computer is not a member of the Exchange Domain Servers Security Group and failed to add it to that group. While there may be other causes of this error, it can happen because the Distinguished Name (DN) of the server has changed. This change in the DN can occur because the computer may have been moved to another organizational unit (OU) in Active Directory. This error may show up if even if the server is in the Exchange Domain Servers Security Group. User Action: Stop all Exchange services. If necessary, add the local computer to the Exchange Domain Servers Security Group and restart the System Attendant Service manually. Note that this will cause the Microsoft Exchange Information Store service to restart. |
