I've installed the preview version of SQL Server 2025 with Polybase enabled. We're currently using it on SQL Server 2022. Every variant I've tried to add a datasource results in the same error (e.g.) "'odbc://localhost' contains an unsupported connector location prefix. Refer to product documentation for a list of supported connector location prefixes." This applies for both odbc:// and sqlserver:// I've also tried different variants with CONNECTION_OPTIONS that both contain a Driver reference of a DSN reference. Everything results in the same error.Solved32Views0likes1CommentPolyBase Error: TCP Provider: An existing connection was forcibly closed by the remote host
