You're in the
iis security
group:IIS 6.0 NT Authorization problem, slow response
iis security:
appeares in client browsers. IE processes pages normally without errors, but with delays(sometimes long delays). We have 2003 server system with MSSQL2k on it and asp/asp.net applications running. Previously we had win2k and iis 5.0 and same trouble. IIS uses only NT4 file security when client requests file. My log looks like this(below is only one! real life page request e.g. click on link and result in browser without errors), somehow ie requests 3 times one file but client doesn't even imagine this. username LogTime processingtime TMS\Edvard 2004.11.04 13:58 265 - 2004.11.04 13:58 0 - 2004.11.04 13:58 0 servicestatus win32status target 200 0 /abons/seek.asp 401 0 /abons/seek.asp 401 -2146893042 /abons/seek.asp Searched all net, no answer..only releated symptoms found on support.microsoft therefore please help me to find answer to questions below: Any one knows hot to receive in 832911 article listed trouble hotfix? And how to solve article 297210 if i have iframes in pages, but no chance to rewrite code without iframes or no chance to use other than NT authorization?
The reason those 401 errors show up in the log file but not IE is because
they are part of an expected authentication handshake. Modern browsers do a LOT of such type of processing on your behalf such that multiple request/response of various status code could be automatically negotiated even if all YOU saw was clicking on a single hyperlink. The sequence of 401.2 -> 401.1 -> 200 is expected when the browser negotiates the 3-way handshake with the server for Integrated Authentication. However, it's not supposed to happen on every single request -- if that happens, it suggests that *something* is closing the connection aggressively. Some possibilities include the web application is coded that way, maybe you have KeepAlives disabled on IIS, or maybe the client is intentionally re-negotiating. If you also saw the problem on IIS5 prior to IIS6, it is almost certainly not a problem with IIS but rather with something you did. 832911 has nothing to do with your situation. 297210 mentions the behavior is by design for security reasons (opening a cross-frame must re-authenticate), so you have no choice if you use IFrames and Integrated Authentication. So far, everything you have said is "by-design". What do you mean by "every 1-5 seconds I receive in IIS 6.0 log 401 errors..." -- is the browser making any requests? Are you sure those 401 errors are caused by your browser and not someone else? Can you give more context, such as a network trace, of your claimed slow response? -- //David IIS This posting is provided "AS IS" with no warranties, and confers no rights. // [quoted text, click to view] "Janis Buks" <Janis Buks@discussions.microsoft.com> wrote in message Every 1-5 seconds I receive in IIS 6.0 log 401 errors but none of themnews:1562A277-3C5E-4A54-B2ED-514A2F2ED972@microsoft.com... appeares in client browsers.

Thank you for your reply, I think problem is not in network side...either it
is IIS +NT4 domain server miscofiguration either asp applications are lame. Maybe this will show whats going on in my asp appplications when they are slow IISState log: *********************** Starting new log output IISState version 3.0 Tue Nov 02 15:52:20 2004 OS = Windows 2003 Server Executable: w3wp.exe PID = 304 Note: Thread times are formatted as HH:MM:SS.ms *********************** Thread ID: 0 System Thread ID: bbc Kernel Time: 0:0:0.15 User Time: 0:0:0.46 *** ERROR: Symbol file could not be found.

I do not think authorization has anything to do with your slows response.
You have several requests which are stuck waiting for a non-existent thread -- so they are going to hang until some timeout happens. I noticed some DB calls made by your ASP pages. I suggest you at least install this QFE to remove one possible hang possibility on WS03. http://support.microsoft.com/default.aspx?scid=kb;en-us;838306 -- //David IIS This posting is provided "AS IS" with no warranties, and confers no rights. // [quoted text, click to view] "Janis Buks" <JanisBuks@discussions.microsoft.com> wrote in message Thank you for your reply, I think problem is not in network side...either itnews:CDAA5449-B322-4116-BD5C-8BD5E1EB4443@microsoft.com... is IIS +NT4 domain server miscofiguration either asp applications are lame.

IISState shows only that what I already know, how i could point out the
problem? "You have several requests which are stuck waiting for a non-existent thread" and this is the problem so far. I don't know why but IIS proccesses pages sometimes very very slow (even simple html not asp) Here is the asp code example that we have in average all our pages: <% var qstring="dsn=mydsn;uid=user;pwd=pass" var ServerConnection=Server.CreateObject("ADODB.Connection"), RecordClone, query; //Initialize server connection function CreateServer() { ServerConnection.Open(qstring); } //Finilize server connection function DeleteServer(){ ServerConnection.Close(); ServerConnection=null; } //Function than runs sql query and in case of error parses error description function runSQL(query) { try { RecordClone=ServerConnection.Execute(query); return RecordClone; } catch (exception) { Response.Write("<!--ERROR WAS ON PAGE: "+exception.description+"-->"); } } CreateServer(); .... var data = runSQL("select xx from yy"); //lots of simple queries runSQL("update xx set yy=zz"); .... DeleteServer(); %> Nothing special as you see. ODBC connection, some simple queries, html output and thats all. Same sql queries which I launch in asp, through query analyzer runs in 0 secs We have windows2003, sql2000, iis6 and asp/asp.net applications on it, also sometimes we access sql server through access 2000/xp applications.Previously we had win2k and iss5 same trouble.

Try asking microsoft.public.inetserver.iis , which has more traffic than
this newsgroup. There are people who knows how to optimize/write ADO code there. I think you have issues with your pages/data-access and not security. Many people run the same sort of things as you do without issues. -- //David IIS This posting is provided "AS IS" with no warranties, and confers no rights. // [quoted text, click to view] "Janis Buks" <JanisBuks@discussions.microsoft.com> wrote in message IISState shows only that what I already know, how i could point out thenews:9AC84828-56F1-4957-A035-DAB7C92AD435@microsoft.com... problem?
