In my recent article on installing an Exchange Server 2. Database Availability Group I gave the example of using a Windows Server 2. Exchange server as the file share witness for the DAG. In this article I will take a more detailed look at the requirements for that scenario. To begin with, this is what you would likely see if you tried to use a Windows Server 2. The task was unable to create the default witness directory on server your server name. Please manually specify a witness directory. If you take that advice and specify a witness directory you will still receive an error. The Exchange Trusted Subsystem is not a member of the local Administrators group on specified witness server your server name. Unable to access file shares on witness server your server name.

The database recognizes 1,746,000 software titles and delivers updates for your software including minor upgrades. Creating an Exchange 2013 DAG causes an error the Exchange Trusted Subsystem is not a member of the local Administrators group on specified witness server. Until this problem is corrected the database availability group may be more vulnerable to failures. You can use the Set Database. Availability. Group cmdlet to try the operation again.

Error The network path was not found. At this point you have two options for proceeding. You can remove the newly created DAG since it has just been created and doesnt yet have members, fix the requirements Im about to list below, and then create the DAG again or. Fix the requirements below and run Set Database. Availability. Group to correct the DAG configuration. For this example Ill be taking the second approach, but you can choose either one.

There are three requirements we need to meet The Exchange Trusted Subsystem group in Active Directory must be added to the local Administrators group on the server that will be the file share witness. The File Server feature FS File. Server must be installed on the file share witness. File and Print Sharing must be allowed through the Windows Firewall if the firewall is enabled. So, first add the Exchange Trusted Subsystem group to local Administrators on the file share witness. Next, install the FS File. Server feature by running the following command in Power. Shell.

SCSI Services,File ServerFinally, check the Windows Firewall is configured to allow File and Printer Sharing. Note the File and Printer Sharing step may not need to be manually performed, as it appears that Exchange may enable it automatically anyway. However given that it is a requirement I still perform the manual step anyway. If youre following the second approach as I am you can now run Set Database. Availability.

Witnesses will be created automatically, however it will remain empty until you add DAG membersif you did specify a witness directory then it will not be created until there are DAG members, after which time it will also have the witness folder added. When you have all of those requirements met and youre recreating the DAG from scratch then the DAG will be successfully created. However at the moment you will still see the following error The Exchange Trusted Subsystem is not a member of the local Administrators group on specified witness server your server name. This error is a bug, as it was in Exchange Server 2. Until the bug is corrected in a future update you can refer to the DAG task log files in C Exchange. Setup. Logs. DAGTasks.
