Connection doesn't work when Notebook stored on SharePoint

[AlexSefrin]

I can establish a connection to a SQL Server but as soon as I use a workspace the connection isn't working anymore.

It seems that, when the ipynb file is stored on an SharePoint a connection can't be estabished.

Same Microsoft.Data.SqlClient.SqlException (0x80131904): A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections.

Hey @AlexSefrin - it's not really clear from your description what exactly the problem is. You mention workspaces but also something about Sharepoint? And then the SqlClient error seems to just be a general connectivity issue with reaching the server, which usually indicates a problem outside of ADS.

Could you provide some more detailed repro steps so we can verify if this is an actual issue in ADS or elsewhere?

Hi @Charles-Gagnon ,

I’m still trying to figuring out the dependencies.

It has nothing to do with the workspace, which I firstly thought!

When I save the notebook on a drive where our SharePoint files are stored, I can't establish a DB connection. When the notebook is stored on a normal drive, it is no problem to connect to the servers.

I hope it helps a little bit...
