SQL Server Express CREATE DATABASE permission denied in database 'master'

Question

After I change the option as UserInstance="False", then the error starts to happen.

Because I want to use full-text search, the option change is required. BUT, it stopped to work. Is there any way to make it work again?

I'm running Application Pool as Network Service with full control.

Answer 5

What login are you connecting to SQL Server as? You need to connect with a login that has sufficient privileges to create a database. Network Service is probably not good enough, unless you go into SQL Server and add them as a login with sufficient rights.

3. Click Security > Login > choose your login where you want to create DB > right click then Properties > click server roles > then checklist 'dbcreator'.
4. Close and log in back with your login account.

This worked for me, and hope will help you.

Answer 7

I know, it is an old question, but no solution worked for me. Here is what I did:

USE master 
GO 
GRANT CREATE TABLE TO PUBLIC

Repeat this with every permission you need, for example GRANT CREATE DATABASE TO PUBLIC, ... You must have the server role "public" (yes, I am captain obvious).

Note 1: GRANT ALL TO PUBLIC is deprecated, does not work anymore in 2017.

Note 2: I tried to build an msi installer using the wix toolset. This toolset calls a powershell file, wich creates the databases, ... Just to give you some background information :)

Addition to @Kho dir answer.
