Questions[iis-6](server)

I am deploying my web application on iis6. I kept receive this "windows security" pop up to enter user name and password.. I have already disabled anonymous user, and checked integrated windows authentication but it just wont "automatically" login.

What should i do?

I have check the security settings-local intranet zone: "login as automatic logon only in Intranet zone". Also my production server is a standalone server, and hence might not hold AD account and credentials.

I've got a WCF component that I wrote in VS 2008 (using .NET framework 3.5) installed on a Windows 2003 Server. I've been having some problems using one of the methods, and in an effort to try and debug the problem I've been advised to add some diagnostics to the Web.Config file. Now, this WCF server doesn't get used much at all at this point, so can I just make the edits in the Web.Confilg file, and then run a test with my new client app? Or do I have to stop and restart IIS on the Windows 2003 Server?

The IIS worker processes are taking lot of memory on our servers. I want to limit the memory each application can use. I am confused whether I should set a limit on Virtual Memory Limit, or Private Memory Limit. Each application in our IIS is on its own application pool.

If I set private memory limit to 500MB and virtual memory limit to 3GB. When does the application pool recycle? Does it recycles after reaching 500MB or after reaching 3GB.

I have an ASP.NET application running on a client server (W2k3, IIS6, .NET 2.0). FWIW, this is a Test instance, it hasn't been moved into Production yet. So it is not running under SSL, load balancing, etc.

When I access one of the pages on their server from our office, the page gets hit once. Inspecting the IIS logs (c:WINDOWS\system32\LogFiles\W3SVC1) show a GET for that page, then I push a button on the page and the log file shows a POST. This seems to be working fine so far.

Now when I remote into the client's network and access the page from one of their local machines, the log file shows a GET, then I push the button on the page and the log shows two POSTs at the same second. The first one shows status (sc-status, sc-substatus, sc-win32-status) 200 0 64, the second shows 200 0 0.

In the log file, both POSTs are identical. Basically the log looks like this (except I masked some of the data):

#Fields: date time s-ip cs-method cs-uri-stem cs-uri-query s-port cs-username c-ip cs(User-Agent) sc-status sc-substatus sc-win32-status

The problem is, the page is getting hit twice. The database performs an operation for the first request, then the second request detects that a duplicate operation is being performed and throws an error message. The users think their operation failed, but it actually succeeded.

The error description of sc-win32-status 64 is: "The specified network name is no longer available." This leads me to believe, given that both POST requests show an HTTP status of 200, that the server is successful in serving the request, but the client is never notified and resubmits the request.

• How can I troubleshoot this?

• Any ideas what could be causing this behavior on their internal network only?

• I should mention, this is happening at two separate client sites, but does not happen at six of our other client sites, or in our office, or connecting to any of our eight clients over the web.

• What could be making this reproducible 100% of the time on their local network but 0% of the time anywhere else?

Update: I found a very small number of the duplicated POST requests had sc-win32-status of 995 instead of 64 as originally reported. The error description of sc-win32-status=995 is: "The I/O operation has been aborted because of either a thread exit or an application request." This doesn't make any sense (considering I have full access to the code). I still don't understand how or why this issue is occurring, but the new error code leads me to believe it may not be a network issue after all and I am now investigating the possibility of a random code bug.

My Windows Server 2003 Std server refuses to server ASP.NET content. It serves regular html just fine but anything .net, even a one line html file with an ASPX extention fails silently.

Things I've tried:

• Nothing in the event log or IIS WWW logs when it fails.
• Fiddler shows no response
• I reinstalled .NET with
  • C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727>aspnet_regiis.exe -U
  • C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727>aspnet_regiis.exe -I
• I give obscenely high permissions on everything I can think of (full control, read, write, etc.) to all possibly relevant users (IUSER*, ASP.NET, etc.).
• I confirmed that ASP.Net v1 and v2 Web Service Extensions are "allowed" in IIS
• Confirmed that the Server Manager had IIS and ASP.Net roles enabled

Again: this is the scenario:

• http://localhost/Test/Default.htm <-- Works great!
• http://localhost/Test/Default.aspx <-- Bombs silently with no message at all

Any guidance will be much appreciated!

Solution: I reinstalled per the instructions below and it works now. Thanks all!
