This is the error I get, if you happen to know why :

I restarted my machine and all is well now. I have another problem now though. I have a small ASP.NET application which contains a Login module. When I start my application from visual studio in debug mode, I can authenticate, which is not the case if I call my login module from Cassini Explorer. After that if I try to restart my application from VS2005, I receive a message telling me the resource I am trying to access is already used by another process.

Any ideas?

This might help, the error I generate is the following, I am the only administrator on my machine :

Hello, DevMo!

From your stack trace it seems that you are using Integrated/Windows authentication in the SQL connection string. If that's the case, the difference in behavior between IIS, VS WebDev server and Cassini is understandable, becasue they (and hence your app) run under different user accounts. UltiDev Cassini runs under "Local System" account, while IIS runs under "NETWORK SERVICE", and VS2005 WebDev runs under your personal account. To resolve this you have a couple of options:
- Use SQL login instead of Integrated login in your SQL connection string - a simple but less secure option as you may have to save password in the connection string.
- Create a new login in SQL Server corresponding to "Local System" windows account and map an appropriate database user to the login.

Please let us know if you were able to resolve this issue.
Best regards,

Just to let you know, I am still confronted to this problem. Question: Which of the two solutions you are suggesting is best suited to the following situation.

Our application will have to be deployed from a CD on a computer without Internet connection. Our Setup module will eventually include Cassini merge module as well as SQL Express. I need to make sure our users will not encounter this problem after installing our solution. Our target audience will have no technical skills whatsoever. They will barely know how to put a CD in their computer.

So which of the two solutions will guarantee a reliable configuration on the front-end machine?

Thank you.
DevMo

Another thing :

If I start my ASP.NET application from VS2005 the URL : http://localhost:1324/ASPNET/Default.aspx is called and I can authenticate and run my application without problems. However if I start my application from the Cassini Explorer, the following URL is called : http://MachineName:16742/Default.aspx (The port was configured by Cassini), I get the following error :

Cannot open user default database. Login failed.
Login failed for user 'AUTHORITY NT\SYSTEM'.

I am totally lost here as I am not a system administrator but a project manager trying to evaluate Cassini for an eventual use on some of our medium scale solutions.

Thank you.

Hello, DevMo.

It's very hard to provide an advice on architecture from far away, but (without taking any legal responsibilities) we'd think you will be better off using database user instead of windows user in your connection string if you are shipping the solution on a CD to unplugged users. The problem you are facing should go away after you start using database user to access the database.

We do have an article explaining how to make DotNetNuke, a very popluar open-source ASP.NET 2.0 application, work with Cassini. The article does not go into how to redistribute them together, but it will give you an idea about how database can be configured in SQL Server 2005 in order to be accessible from Cassini application.

Thanks for the quick reply. I will keep you posted on how things go for us. I will eventually post a solution as I understand it, it might help others. As for the legal responsibilities, you do not have to worry with us. We just believe in your solution and we want to support it. We do not have the time nor the will for legal stuff. We think, you will eventually be a major player in the ASP.NET arena if you are not already. So keep up the great work.

Thanks
