Security considerations when giving access to SQL Server db for a web application

- by rem

I need to expose our SQL Server 2008 database for an access from a asp.net web application. This is a new task for me, so I would like to know what basic security requirements are there for configuring software and hardware components of web server and DB Server. Is it OK to have both Web Server (Windows Server 2008) with IIS holding ASP.NET application and SQL Server 2008 on the same machine? Should I have to install additional firewall, like Forefront TMG? Should it be on separate computer? In case a web application is hosted on an external web hosting privider server and SQL Server DB on a our internal server what are "pro's" and "con's" of such configuration?

IPv6 scope id issue with IE

- by eych

I have an ASP.NET website that works with Firefox because FF doesn't need the % in the scope-id to be encoded (%25). The website also works on the same machine using IE because I can leave out the scope-id. However, to access the website from another machine in the network, I need to add the scope-id to the IPv6 address. For some reason, using the scope-id doesn't allow an authentication cookie to be created, and the website keeps going back to the login page. Anyone using IE7+ to access an ASP.NET website on a network using IPv6 with an encoded %?

Other computer can't connect to MySQL Database

- by user23950

I have a VB .NET program the uses a MySQL database. It works when the computer that has WAMP installed is the one running the program. The same program now displays an Unhandled Exception error when the computer it's running on does not have WAMP installed (and running). The only thing that is installed is the MySQL connecter net. How can I make this work? I have already tried opening port 20 by configuring the firewall. I did this for both TCP and UDP.

New Development Snapshot

I finished all the .NET 4.0 security model changes. If you build from source, you can now (optionally) build on .NET 4.0 and get native .NET 4.0 assemblies that use the new .NET 4.0 security model (and also experimental class gc support). The .NET 2.0 binaries also work on .NET 4.0. This is probably the final development snapshot before the first 0.44 release candidate and it has been tested more than a typical development snapshot.

Windows 7 Shortdate Format Ignored

- by Element

I am moving a copy of an ASP.net web application running on a windows server 2003 box to a Windows 7 Laptop. On the win server 2003 box the locale was set to United States and shortdate format was M/DD/YYYY. On the Windows 7 machine it is DD/MM/YYYY which is breaking the application. I have tried changing all the locale settings under controlpanel-regions to United States and rebooting with no luck. I also tried explcitly setting the shortdate format to M/DD/YYYY under the region settings but the web application seems to ignore it. How can I change the Windows 7 shortdate format so an ASP.net application will recognize it ?
