Try to setup a clean DNN 10.1.2 website and always get a timeout during the big INSERT statement of the table "lists". The statement inserts about 5000+ rows into the database and the DNN InstallWizard throws an error after approximately 40 seconds. I can see that about 2800+ rows are already inserted. So I know that everythings works (Website/SQL-Server/Rights/...) but it just takes to long.

Where can I increase the timeout for the complete install script or the insert command. I tried a lot of settings in the webconfig and the SQL-Server the last two days but find no solution. Can anybody please help me and guide me a way where to increase the time limit for the installation wizard script. Thanks in advance for any recommendations.

I am also wondering that the 5000 rows are a problem for the server, because it is a VM with 4 vCPUs and 24GB RAM (OS is MS Windows Server 2025 Standard, SQL-Server is MSSQL2022 Express).

Regards,
Wolfgang

I have installed DNN without issues on way worst machines, the whole install process should take 30 seconds to maybe a minute or 2. I would investigate for server performance issues...

Yes, this is a weird issue.
That server is way faster than my local VM and I have never seen this TBH.

SQL Express does have some processing limits, so it cannot use all of the resources available, but it shouldn't be an issue in this situation, unless the server is already overwhelmed with other activity?
