Error ID: 4387 during the installation of MABS

Justin Dowswell 0

Hey there.

Currently getting an error when trying to install MABS. It gets stuck at the DPM install.

The server meets all the prerequisites i.e. it isn't a domain controller, though it does host a hyper-v VM that is a domain controller.

I have attached my DpmSetup.log.

There seems to be a bunch of errors relating to different things, like failing to update email settings.log, but nothing that should break installation that I would think.

Would love an extra set of eyes on this!

Thanks in advance.

@Justin Dowswell Thank you for reaching out to us on Microsoft Q&A platform.

I see that you are trying to install MABS and encountered an error. You mentioned that all the prerequisites are met. Just wanted to double check/confirm if you are installing MABS on supported OS versions mentioned in the link - https://learn.microsoft.com/en-us/azure/backup/backup-azure-microsoft-azure-backup#using-an-on-premises-server

@SadiqhAhmed-MSFT no worries.

Yes I am installing on a supported OS - Windows Server 2022 Standard.

@SadiqhAhmed-MSFT - thanks for your reply. I did see this thread but my logs do not mention SQI WMI class being broken though? I'm also not getting a Invaild Class error while accessing the SQL services using WMI, that your colleague mentions.

@SadiqhAhmed-MSFT thanks for your reply. I did see this thread, but my logs do not seem to suggest that SQl WMI class is broken. I am also not getting a Invalid Class error while accessing the SQL services using WMI, which this OP was experiencing.

I have the exact same error, but its failing long before it starts installing SQL server.

DpmSetup.log

@Ove Andersen - We are getting below mentioned error while running the setup.

According to the logs, please check if the machine is joined to a domain before installation. If not, please join domain firstly then perform an installation.
Hope this helps and please help to accept as Answer if the response is useful.

It is not joined to a domain, and it will never be as we are running Azure AD only.
Is this a requirement for MABS?

2023-07-19T12:56:04.1966667+00:00

@Ove Andersen - Yes, the Machin should be domain joint to install MABS on it. This is one of the pre-req to install MABS.

You can refer to below mentioned line mentioned on the MABS Article.

"Always join Azure Backup Server to a domain. Moving an existing Azure Backup Server machine to a new domain after deployment is not supported."

Hello Justin,

I have reviwed the logs and it seems the setup failed on 2 places.

Firstly on SQL Permission issue for for local account 'STEWARD\MICROSOFT$DPM$Acct'.

<Snip>

[17/07/2023 12:53:27 PM] Information : Configuration Post SQL Service Start. Add local user account to SysAdmin [17/07/2023 12:53:27 PM] * Exception : Ignoring the following exception intentionally => System.Data.SqlClient.SqlException (0x80131904): Cannot drop the login 'STEWARD\MICROSOFT$DPM$Acct', because it does not exist or you do not have permission. at System.Data.SqlClient.SqlConnection.OnError(SqlException exception, Boolean breakConnection, Action`1 wrapCloseInAction) at System.Data.SqlClient.TdsParser.ThrowExceptionAndWarning(TdsParserStateObject stateObj, Boolean callerHasConnectionLock, Boolean asyncClose) at System.Data.SqlClient.TdsParser.TryRun(RunBehavior runBehavior, SqlCommand cmdHandler, SqlDataReader dataStream, BulkCopySimpleResultSet bulkCopyHandler, TdsParserStateObject stateObj, Boolean& dataReady) at System.Data.SqlClient.SqlCommand.FinishExecuteReader(SqlDataReader ds, RunBehavior runBehavior, String resetOptionsString, Boolean isInternal, Boolean forDescribeParameterEncryption, Boolean shouldCacheForAlwaysEncrypted) at System.Data.SqlClient.SqlCommand.RunExecuteReaderTds(CommandBehavior cmdBehavior, RunBehavior runBehavior, Boolean returnStream, Boolean async, Int32 timeout, Task& task, Boolean asyncWrite, Boolean inRetry, SqlDataReader ds, Boolean describeParameterEncryptionRequest) at System.Data.SqlClient.SqlCommand.RunExecuteReader(CommandBehavior cmdBehavior, RunBehavior runBehavior, Boolean returnStream, String method, TaskCompletionSource`1 completion, Int32 timeout, Task& task, Boolean& usedCache, Boolean asyncWrite, Boolean inRetry)

Secondly on creating the Report Databases.

ClientConnectionId:638d4487-d49f-46da-8286-9dd82745fa12 Error Number:15151,State:1,Class:16 [17/07/2023 12:53:28 PM] Information : Using WMI namespace '\\STEWARD\root\Microsoft\SqlServer\ReportServer\RS_SSRS\V16\admin' [17/07/2023 12:53:28 PM] Information : found instance 'SSRS' [17/07/2023 12:53:28 PM] Information : Starting Service:SQLServerReportingServices on machine:STEWARD flag restart:True [17/07/2023 12:53:29 PM] Information : Generating script to create new RS databases [17/07/2023 12:53:29 PM] * Exception : => DPM Setup is unable to update the report server configuration to configure e-mail settings.Log on to NO_PARAM. On the Start menu, point to All Programs, point to Microsoft SQL Server, point to Configuration Tools, and then click Reporting Services Configuration. In Configure Report Server, update the e-mail settings.Microsoft.Internal.EnterpriseStorage.Dls.Setup.Exceptions.ReportingConfigurationException: Failed to Invoke SQL Api GenerateDatabaseCreationScript at Microsoft.Internal.EnterpriseStorage.Dls.Setup.PrerequisiteInstallation.PreReportingConfiguration.InvokeMethodHelper(ManagementObject targetObject, String methodName, Dictionary`2 arguments, ManagementBaseObject& outputObject, Int32 resultToIgnore) *** Mojito error was: ReportServerConfigFailed; 0; None

So, request you to check and follow below mentioned things on MABS Server.

Open SSMS, check for local account 'STEWARD\MICROSOFT$DPM$Acct' and give sysadmin permission to this account

Secondly Open SSRS and create a report database manaully and use below mentioned configuration.

Service Account: ‘Use built-in account’ should be Network Service

Web Service URL: ‘Virtual Directory’ should be ReportServer_MSDPMINSTANCE(make sure that the URL is getting open without any errors)

Database: DatabaseName should be ReportServer$MSDPMINSTANCE

Web Portal URL: ‘Virtual Directory’ should be Reports_MSDPMINSTANCE(make sure that the URL is getting open without any errors)

Then again try to run the MABS Setup and hopefully it will work without any errors.

@SadiqhAhmed-MSFT apologies Sadiqh. Installing SSMS and SSRS has required reboots in between, which I've had to schedule at night, as the server in question runs core systems. I have yet to complete all the steps you've provided, but trust that I will be back here after I have attempted them all!

So there happens to be a report database with that name that already exists. I have tried to find a method to delete this database so I can make a fresh one to no avail. Is there a way to do this?

@Justin Dowswell - If the data base is already exists then you don't have to make any changes in it. Just make sure Web Service URL & Web Portal URL works without any issue. If it is working and then try to run the MABS setup and check if its gets successfully completed or not.

@Amardeep Saini - both the web service URL and web portal URL do not work, throws back an access/check if its running error. I also tried running the install again as you advised, and ran into the original error.

After some more investigation I think I have discovered remnants of an older version of a Microsoft SQL Server install, as well as remnants of a older version of a Reporting Database. There are no entries for these in Apps or Features. I have only been to my org for less than a year, and have inherited this server.

MSSQL14.MSDPMINSTANCE which I believe is Microsoft SQL Server 2017?

Is there a method or tool to remove this Reporting Database that is running on this older version? As I believe this may be the issue, the database already exists but is running on an older version.

@Justin Dowswell - I would advise if possible, reinstall the OS on the server and then again try to install MABS which would be the fastest way to fix all the error you are encountering.

If OS rebuild is not an option then I would request you to delete SSRS encryption key and then try to check the URLs which might works. Once it is working then try the MABS setup again.
