Hi @coskun_0070,
Thank you for your patience. I know how frustrating this can be, especially for something as simple as an installation. As Alana stated, this is the first time we have really seen this issue and your architecture is a very typical setup for our users. Normally the only thing you need to do is specify your SQL Connection string to your SQL Server and this install without issue.
Typically when installing using the Inedo Hub, if you have the connection string using Integrated Authentication it will use the current user's account to connect to the database and any file access needed while installing. Once it is installed, it will then use Network Service by default, but you can change the account the service and IIS run as. If you specify a SQL auth based username and password in the connection string to your SQL server in Inedo Hub, Inedo Hub will then use that account to connect to SQL server, the current user for any file access needed during the installation, and then it will default the Service and Web App to run as Network Service.
With all that being said, I don't think it is the Network Service account that is having issues because that will only be used after the installation. This almost sounds like the .NET Framework failed to install some needed components to connect to SQL Server. That would explain why installing SQL Express fixed the installation issue for you. Would it be possible to install SQL Server Express on your server then try to install ProGet using Inedo Hub with a connection string using sa
pointing to your SQL Server instance on the other machine?
One last thing to try is to temporarily turn off Windows Firewall on your server. I'm wondering if Inedo Hub got blocked trying to communicate to SQL Server and that is causing this issue as well.
Thanks again for your patience and for working with us on this issue.
Thanks,
Rich
