• Losing Windows Authentication intermittently

  - by Mark Robinson

  I'm running a website on IIS6 / Server 2003 which uses Integrated Windows Authentication on a local intranet. I can browse to the site but get intermittent "Object null" errors when calling the following C# code which is called on every request: .... GetUserIdFromPrincipal(User) .... public static string GetUserIdFromPrincipal(IPrincipal principal) { return principal.Identity is WindowsIdentity ? (principal.Identity as WindowsIdentity).User.Value : principal.Identity.Name; } (Apologies for the code sample but was torn between SF and SO but think this is more to do with server config). So as the error is intermittent clearly Windows Auth is working on some level but after navigating around the site for several clicks I get the null reference error meaning IPrincipal is null (I thought this should never be null in ASP.NET). The error only happens on this newly built VM. The code is fine on other machines. Does IIS request the Windows Auth details on each request? What would cause such an intermittent problem? Any help or suggestions would be much appreciated.

• IIS replication - Is it possible

  - by Ian

  Hi All, I have a requirement for a client that I have a centralised system that all his satellite branches can work on. Currently this is a ASP.net web forms app running under IIS 7 on win 2008 RC 2 using an SQL backend. The client has now requested that each branch have a local server, so that in the event that the internet connection is down, the branches productivity does not suffer. His other request is that everything can be updated via the central hub and using some mechanism the updates filter down to the individual sites. What are my options here? I see the following as possible options: Multiple redundant internet connections controlled by load balancers SQL replication for the DB (What is better, snapshot, merge or transactional) Roll my own IIS sync service the periodically checks if there is a new version of the web app and downloads it (I hope there are better option than this) Something way better I don’t yet know about (I hope this is the one I need) One of my clients concerns are that the branches are often in very remote areas where everything from technicians to internet is hard to find and very scarce. Any ideas, suggestions, tips etc are welcome. Thanks all

  Possible Duplicate: What does Windows 8 mean for the future of .NET? Ok, I read this question and someone pointed that C# will be sidelined in next version of windows. There is a link in that question pointed at another link, i.e. this one: Dumping .NET - Microsoft's Madness Is that true that .Net will be dumped by Microsoft in Windows 8? Someone with insider information please share with us your opinions. I'm deeply worried about this.

• 503 Error After Microsoft Request Routing Is Installed - 32 bit 64 bit madness

  - by KenB

  I have a requirement to install the Microsoft Request Routing component for IIS 7.5 running on a Windows 2008 R2 SP1 64Bit machine. After installing Microsoft Request Routing via the Web Platform installer our ASP.NET 4.0 application gets a "HTTP Error 503. The service is unavailable." The Windows event log error details says: The Module DLL 'C:\Program Files\IIS\Application Request Routing\requestRouter.dll' could not be loaded due to a configuration problem. The current configuration only supports loading images built for a AMD64 processor architecture. The data field contains the error number. To learn more about this issue, including how to troubleshooting this kind of processor architecture mismatch error, see http://go.microsoft.com/fwlink/?LinkId=29349. I can make this error go away by changing the application pool to run in 32 bit mode by changing the "Enable 32-Bit Applications" setting to true. However I would prefer not to have to do that to resolve the issue. My questions are: Why is the Microsoft Request Routing feature trying to load a 32 bit version, isn't there a 64 bit version for it? How do I resolve this issue without having to change my application pool to a 32 bit mode?

• When Your ASP.NET MVC Custom Error Doesn't Render...

  You've put [HandleError] on your controller and you've set <customErrors mode="On"> in the web.config file. So why do you still see the yellow screen of death?

• IIS 7 much slower than IIS 6

  - by JoeJoe

  I have a asp.net 3.5 web application running fine on Windows2003 IIS6. I published same exact application to IIS7.5 (Win2008R2) on a faster box (i5,8Gram) and it is significantly slower. 5-6 sec per page vs. 1-2 sec per page. During that time the Task Mgr CPU is always under 10%. Both attach to same database on other box. Benchmark is consistent from any other client browser or machine. I have connection pool on both, compression on both. Same network subnet. Forms authentication (no SSL yet). Can you give me steps on how to troubleshoot where the delays are being inserted or settings in IIS7 that I may have overlooked. Just using defaults. There is only 1 web site on each box. I understand the roles of an Application as defined in IIS has changed. There is no special Application defined in IIS.

• Problem running MVC3 app in IIS 7

  - by mjmoore99

  I am having a problem getting a MVC 3 project running in IIS7 on a computer running Windows 7 Home-64 bit. Here is what I did. Installed IIS 7. Accessed the server and got the IIS welcome page. Created a directory named d:\MySite and copied the MVC application to it. (The MVC app is just the standard app that is created when you create a new MVC3 project in visual studio. It just displays a home page and an account logon page. It runs fine inside the Visual Studio development server and I also copied it out to my hosting site and it works fine there) Started IIS management console. Stopped the default site. Added a new site named "MySite" with a physical directory of "d:\Mysite" Changed the application pool named MySite to use .Net Framework 4.0, Integrated pipeline When I access the site in the browser I get a list of the files in the d:\MySite directory. It is as if IIS is not recognizing the contents of d:\MySite as an MVC application. What do I need to do to resolve this?

• Server redirect

  - by Tyy

  I have asp.net app XYZ which requires SSL. I am supposed to work with IIS that has only one Web Site - DefaultWebSite - containing multiple apps and virtual directories (3rd party). So, my app is located at domain.com/XYZ. I have to meet these conditions: 1.) requesting DefaultWebSite (domain.com) will run my app. It could redirect to ../XYZ, but I would rather not to. If it has to be done this way, requesting DefaultWebSite or my app over both HTTP and HTTPS will always ends up with redirecting to https://domain.com/XYZ 2.) I can't touch any other apps or virtual directories, can't create additional Web Site, can't set DefaultWebSite to require SSL, ... EDIT: 3.) transmitted data (GET or POST) must be preserved I tried to: set Web Site root directory to my app, but it this caused other apps to crash because of my Web.config (not sure why). set up HTTP redirect on DefaultWebSite to https://domain.com/XYZ. This seems to work correctly, but this doesn't work if user requests my app directly (redirected to domain.com/XYZ/XYZ, or redirect loop). set up Default Document, but this seems to work only if it is located in the Web Site root directory. I know I could write simple .aspx with Response.Redirect, but... is there any better solution? Am I missing something?

• Connections to IIS sometimes get stuck in CLOSE_WAIT state

  - by randomhuman

  Our application includes an ASP.Net web service that only needs to deal with a handful of clients. As such, the 10 incoming connection limit of Windows XP Pro is generally not a problem. However, on one particular server, connections are occasionally becoming stuck in the CLOSE_WAIT state. These connections build up over time and eventually new client connections are refused because the maximum number of connections are used up. From my googling it sounds like a failure of the webservice to properly close the connection can cause this problem, but as it works just fine on hundreds of other Windows XP pro machines I can't see it being a bug in our code. It also ran fine on the affected machine until some shenanigans on the part of the end user (I think they set about deleting duplicate files in order to reduce their disk usage, but they did not exactly come clean about it). What could the user have changed to introduce this problem? Is there any way I can force connections that are in CLOSE_WAIT to time out rather than letting them hang around? I have seen suggestions to reduce TcpTimedWaitDelay, but that only relates to the TIME_WAIT state, and changing it did not have any effect.

• The fastest way to resize images from ASP.NET. And its (more) supported-ish.

  Ive shown before how to resize images using GDI, which is fairly common but is explicitly unsupported because we know of very real problems that this can cause. Still, many sites still use that method because those problems are fairly rare, and because most people assume its the only way to get the job done. Plus, it works in medium trust. More recently, Ive shown how you can use WPF APIs to do the same thing and get JPEG thumbnails, only 2.5 times faster than GDI (even now that GDI really ultimately...Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors?

• Old network login passed to IIS

  - by 300 baud

  Let me start by saying that I am not a server guy - I am a developer. But I develop and manage an ASP.NET application that uses Windows authentication. I've run into the problem I am about to describe before, and I would just like to understand how to remedy it since I am the one who always gets the original support request. A user, let's call her JaneDoe, has just gotten married and her login has been changed to JaneJones. We have an application that uses Windows authentication to store the user's login name to a table and then redirects the user to another non-Windows authenticated site with a GUID which points to the table entry we just made. When the user reaches the second site, we read in the login name from the database using the GUID that was passed. Then, we look up the login name in another database where we track application permissions. The problem is that the user is logging into her workstation as JaneJones, but the Windows authenticated site is still receiving a login name of JaneDoe. Is this a domain controller issue? Is it a workstation issue? What's the best way to resolve this?

• Putting the Con (COM1, LPT1, NUL, etc.) Back in your URLs

  One annoyance that some developers have run into with ASP.NET MVC is that certain reserved filenames are not allowed in URLs. The specifics of this restriction are accounted for in an interesting blog post entitled Zombie Operating Systems and ASP.NET MVC. This actually wasnt a restriction on ASP.NET MVC but was built into the core of ASP.NET itself. Fortunately, ASP.NET 4 fixes this issue with a new setting. In web.config, simply add <httpRuntime relaxedUrlToFileSystemMapping="true"/> to...Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors?

• WCF errors in VS 2010/.Net 4 using sample publish/subscribe app from IDesign website

  - by Bill

  I am attempting to compile/run a sample WCF application from Juval Lowy's website (author of Programming WCF Services & founder of IDesign). The application is an example of a publish/subscribe 'traffic-light' application that requires using VS 2010/.Net 4. This is my first attempt at using anything other than VS 2008/Net 3.5. Initially I recieved the following binding error: "Configuration binding extension 'system.serviceModel/bindings/ netOnewayRelayBinding' could not be found."

• Uploads fail with shorewall enabled

  - by JamesArmes

  I have an Ubuntu 8.04 server with shorewall 4.0.6 installed. When I try to upload files using FTP, SCP, or cURL the file upload stalls almost immediatly and eventually times out. If I turn off shorewall then the uploads work fine. I don't have any rules that specifically allow FTP and I'm not too concerned with it, but I do need to be able to upload via 22 (SCP) and 80 & 443 (cURL). This is what my rules look like: COMMENT Allow Server to respond to any web (80) and SSL (443) requests ACCEPT net $FW tcp 80 ACCEPT $FW net tcp 80 ACCEPT net $FW tcp 443 ACCEPT $FW net tcp 443 COMMENT Allow Server to respond to SNMPD (161) requests ACCEPT net $FW udp 161 COMMENT Allow Server to respond to MySQL (3306) requests (for MySQL Graphing) ACCEPT net $FW tcp 3306 COMMENT Allow Server to respond to any SSH connection attempts, and to SSH out. SSH/ACCEPT net $FW SSH/ACCEPT $FW net COMMENT Allow Server to make DNS Requests out. DNS/ACCEPT $FW net COMMENT Default "close" anything else. Ping/REJECT net $FW ACCEPT $FW net icmp #LAST LINE -- ADD YOUR ENTRIES BEFORE THIS ONE -- DO NOT REMOVE I expected the top four ACCEPT lines to allow inbound and outbound traffic over 80 and 443 and I expected the two SSH/ACCEPT lines to allow inbound and outbound trffic over 22, including SCP. Any help is greatly appreciated. /etc/shorewall/policy contains the following (all lines above are commented out): # # Allow all connection requests from teh firewall to the internet # $FW net ACCEPT # # Policies for traffic originating from the Internet zone (net) # Drop (ignore) all connection requests from the Internet to the firewall # net all DROP info # THE FOLLOWING POLICY MUST BE LAST # Reject all other connection requests all all REJECT info #LAST LINE -- ADD YOUR ENTRIES ABOVE THIS LINE -- DO NOT REMOVE
