SQL SERVER – FIX – A connection cannot be made to redirector. Ensure that ‘SQL Browser’ service is running. (Microsoft.AnalysisServices.AdomdClient)

Life gives you learning lessons from unexpected times, here is one such experience that I felt is worth sharing. It may be a surprise to my blog readers that I also have SQL Server Analysis Services installed on my primary machine. I use it occasionally because most of the time I work with the SQL Server Database engine. One fine day, I opened SQL Server Management Studio and instead of a database engine, I selected analysis services (this was a mistake) and pressed on the connect button. Below is the error which I received for SQL Browser:

ADDITIONAL INFORMATION:
A connection cannot be made to redirector. Ensure that ‘SQL Browser’ service is running. (Microsoft.AnalysisServices.AdomdClient)
——————————
No connection could be made because the target machine actively refused it 127.0.0.1:2382 (System)

This is the first time I saw such error while connecting to SQL Server, but soon I realized that I was trying to connect to SQL Server Analysis Services. I could have left it there because I don’t use it, but I did not. Since there was a little time, I thought it is worth solving this challenge in front of me. Here is the step by step resolution of what I did:

  1. Made sure that SQL Server Analysis Service was up and running. This got confirmed from my SQL Server Configuration Manager.
  2. As I do always, read the error message again and verified that the SQL Browser service was up and running.
  3. Since this was a local connection, I turned off the firewall as well.

None of the above solved the problem. The Port resolution is done by the SQL browser service in case of SQL Server connectivity. So I thought that it could be a permission issue – just a guess based on the error message.

I noticed that SQL Browser was running with the local system account. I found on the internet that changing account helped many. So I used the SQL Server Configuration Manager to change the service account for the SQL Server Browser. I have used below.

Here are the steps:

  • Open SQL Server Configuration Manager
  • Right click “SQL Server Browser” and choose “Properties”
  • In the “Log On” Tab select “Local System” under “Built-In” account.

Have you ever seen such error and found some other way to fix it? Please comment and let others also know. The best way to learn something is by sharing.
