Windows 10: SQL Server Single User Mode Problem

Ferlin Pedro · Jun 9, 2025 at 8:57 AM

I'm trying to recover the sysadmin password. Mixed authentication set. Unable to get SQL Server in Single User mode working. I tried local administrator accounts but keep getting the following error: Reason: Server is in single user mode. Only one administrator can connect at this time..All SQL services stopped and only two were started when the service starts. The service itself and the integration services. Both of those services run as NT users defined by the SQL Server installation. I've also tried: net start MSSQLSERVER /m"sqlcmd"The GUI produces the same output when done f

SQL Server + Python — What’s new

Python is one of the most popular and fastest-growing languages used today. Pyodbc (Python-SQL Server Connector) is an open source Python module maintained by Michael Kleehammer that uses ODBC Drivers to connect to SQL Server. It allows you to connect from the platform of your choice to SQL Server on-premises and in the cloud. Pyodbc is also cross platform and can be installed using pip.

We recently announced SQL Server v.Next CTP1 on Linux and Windows, which brings the power of SQL Server to both Windows and — for the first time ever — Linux. You can now connect your applications to SQL Server running on Linux, Windows and macOS (with Docker).

For our Python developers, we have a few updates that will improve Python connectivity with SQL Server. Pyodbc is now:

Officially supported: You can contact Microsoft Customer Service and Support (CSS) via phone, email, Twitter, forums, etc., to report and get help with any issue.

Available in Jupyter Notebooks for SQL Server: The Jupyter Notebook is a web application that allows you to create and share documents that contain live code, equations and visualizations.Pyodbc and its dependencies ship out of the box with Juypter notebooks on Azure. To get started, go to notebooks.azure.com and create a new Python 2 notebook or follow the instructions here. Check out the code sample and paste it in your notebook’s interactive prompt to get started.

Compatible with Python 3.5 and Django 1.10 through Django-pyodbc-azure.

SQL Server + PHP – What’s new

PHP is one of the most widely used programming languages for web developers today. The Microsoft PHP Connector for SQL Server is used to connect PHP applications to SQL Server, whether SQL Server is hosted in the cloud, on-premises or provided as a platform as a service.

We recently announced SQL Server v.Next CTP1 on Linux and Windows, which brings the power of SQL Server to both Windows and — for the first time ever — Linux. Developers can now create applications with SQL Server on Linux, Windows, Docker or macOS (via Docker) and then deploy to Linux, Windows, or Docker, on-premises or in the cloud.

As part of this announcement, we have made some improvements to our PHP connector:

SQL Server v.Next Support: You can now use the PHP connectors to connect to SQL Server v.Next CTP1 of SQL Server running anywhere, including SQL Server on Linux, Windows or Docker.

Linux support: We’ve created Linux-native versions of sqlsrv and pdo_sqlsrv modules of the PHP SQL Server Connector. Now you can use the PHP Connector to connect to SQL Server on Ubuntu 15.04, 15.10, 16.04, Red Hat 6 and Red Hat 7.

PHP 7.0 and 7.1 support: We have added support for the latest PHP runtimes for Windows and Linux with our releases on GitHub.

PECL Install Experience for Linux: We have created native PECL packages for Linux. This enables developers to install, upgrade and uninstall the PHP SQL Server connector using the PECL package repository. This is explained in detail in our Getting Started tutorials.

Community input for prioritization: We have also started using surveys on GitHub to guide our prioritization for features and improvements. Check our latest survey and let us know what you think.

Get started today

Check out the PHP connector source code on GitHub and our packages (sqlsrv, pdo_sqlsrv) on PECL. Make pull requests and let us know what you think.
