Disabling Deprecated feature sp_configure Remote access

-> We had an audit on the database servers. An auditor advise us that “Remote access” feature should be disabled due to below reasons,

[$] It is an obscure SQL Server to SQL Server communication feature that is deprecated feature. Please refer article for more details.

-> It was decided that we should disable it on our SQL Server instances. We disabled it using below code,

EXEC sp_configure 'remote access', 0 ;  


-> Right Click SQL Server Instance -> Properties -> Connections -> Uncheck “Allow remote connections to this server”,

-> Please note that a restart of SQL Services is required for the changes to take effect.

-> We faced below issues after disabling sp_configure ‘remote access’ on our SQL Server instances.

Log Shipping

-> Logshipping main functionality as a whole such as backup, copy and restore works fine without issues. But the reporting part utilizing SQL Server Management Studio “Transaction Log Shipping Status” report displays incorrect information.

-> LSAlert job on Monitor servers fails as it is not able to get upto date information from Primary and Standby Instances.

-> The issues related to SSMS “Transaction Log Shipping Status” report and LSAlert job seems to be due to the fact that it is not able to get proper data from Primary and Standby server as the linked server fails with below error,

Could not execute procedure on remote server ‘LOGSHIPLINK_JBSAG4_200666876’ because SQL Server is not configured for remote access. Ask your system administrator to reconfigure SQL Server to allow remote access.

-> ‘LOGSHIPLINK_JBSAG4_200666876’ is a System Linked server that is created as part of Logshipping. I dropped this linked server and recreated using sp_add_linkedserver and was able to see same behaviour. I tried this step on a test server.

-> I checked the trace further and understood that the linked server errors out when trying to run below command remotely,

select @linkcmd = quotename(sys.fn_MSgetlogshippingmoniterlinkname(upper(@monitor_server))) + N’.msdb.sys.sp_processlogshippingmonitorhistory’
exec @retcode = @linkcmd
                    @mode = @mode
                    ,@agent_id = @agent_id
                    ,@agent_type = @agent_type
                    ,@session_id = @session_id
                    ,@session_status = @session_status
                    ,@monitor_server = @monitor_server
                    ,@monitor_server_security_mode = 1
                    ,@database = @database
                    ,@log_time = @log_time
                    ,@log_time_utc = @log_time_utc
                    ,@message = @message

-> This is when I realized that the linked server utilizes RPC Out that is “Remote Procedure call” to execute above function remotely on Primary and DR to fetch the details. Linked servers with “RPC out” true will require Remote access to be turned on and this seems to be the root cause of our issue.

-> Linked Servers with RPC out set to false doesn’t have any issues and will function normally. But in our case, SSMS “Transaction Log Shipping Status” report and LSAlert job needs “RPC Out” set to true on Linked Servers to get the data remotely and display it as appropriate.

Linked Servers

-> The lab utilizes 2 database servers JBSAG1 and JBSAG2. Remote access option is disabled on both servers. A linked server for JBSAG2 is created on SQL Server Instance JBSAG1,

Remote Access

Linked server property

-> Querying a remote object Table1 using Linked server. It works fine,

-> Querying a remote View vw_table1 using Linked server. It works fine,

-> Querying a remote Stored procedure sp_table1 using Linked server. It returns an error that remote access option is required,

-> As a workaround, I will utilize “Execute AT” to execute remote Stored procedure sp_table1 using Linked server. It works,

Always On

I have setup a lab with 3 Always on replicas (2 in East US and 1 in Korea Central), testing was performed on the lab with Remote Access turned off,

[$] Create an Availability group.
[$] Drop an Availability group.
[$] Suspend and resume availability databases.
[$] Load the availability database and create issues such as HADR_SYNC_COMMIT, Redo latency, high log send queue etc.
[$] Check Always On dashboard several times.
[$] Failover and failback manually.
[$] Failover and failback automatically.

I did not see any issues on above scenario with remote access turned off. All above tests with remote access off were exhibiting same behavior as remote access on.


Discuss above points with your team and decide if things that will break as mentioned in this blog is required for your team and decide further.

In my case, many of our database servers has Logshipping and Linked servers configured. We had issues atleast on Logshipping as we make use of LSAlert and SSMS “Transaction Log Shipping Status” report day in and out. Hence, we provided this justification and left remote access on.

If there are any other features that make use of Remote Access which I have missed in my post. Please advise those in comment section.
