IIS6 APS Thread
Is there an explanation somewhere as to how IIS6 determins how many ASP threads its actually going to use?I have configured IIS6 to have 20 threads (ASPProcessorThreadMAX) but it uses them all.
I am using the MACT test tool to stress test and with 50 concurrent users I quite often see only a single ASP thread being used the other 49 are on the Requests Queued. The Request Wait Time in Perfmon can be averaging around 5 or 6 seconds and there is plenty of spare CPU.
The application quite often has long running queries(15 to 20 seconds per request)and rather than use another thread IIS will quite often just keep ticking along with the threads its using with the result that the Request Wait Time can jump significantly.

I am writing a new asp.net program. Here in, the user has to click on a
button on a web page, and a new excel sheet should open up.
I could do it successfully using Office 2k3 PIA's for the click event handler for the button. Then I decided to create a new thread and complete the process of creating an excel sheet in the new thread itself.
But I am getting the following error.
An unhandled exception of type 'System.UnauthorizedAccessException' occurred
in Unknown Module.
Additional information: Access is denied
But, the code executes successfully when i remove the thread and directly
code it in the click event handler for the asp button.
What might be the problem?? How can I give access permission to the thread??
Should set some permission in the Internet Information Services Manager.

Does the issue posted in http://support.microsoft.com/?kbid=243543 apply to IIS 5.0 and IIS 6.0 whereby storing objects in session or application objects causes thread affinity thus removing all benefit of a thread pool

Here's a question that I've not been able to get a definitive answer to.
Creating an STA object (such as a typical VB6 object) and assigning to the
ASP Session store is a bad thing.
It's a bad thing because it forces IIS to affiliate the Session with the
Thread on which the STA object is created.
This means all subsequent requests for that session can only be handled by
that worker thread and can therefore result it in poor performance as
requests queue up to access the thread they are affiliated with.
My question(s) is/are this:
Is this affilation now set in stone for the life time of the session?
Does removing the STA object from the session remove the affiliation or is
IIS/ASP just not that clever?

I am using ASP + IIS + MS access, when running the following codes:

I'm currently testing a version of Win2003 to evaluate a migration of our
NT4 server, but I got some troubles with Office Web Component 9 (office
2000), it seems it doesn't work anymore, and I can't find the issue.
When I make a Set objSpreadsheet = Server.CreateObject("OWC.Spreadsheet"), I
got an error :
Server object error 'ASP 0177 : 800401f3'
Server.CreateObject Failed
/test/include/./include_asp/excel-class.asp, line 10
800401f3
So I thought it was a "Web service extension" problem, prohibited por
default by IIS6, I authorized MSOWC.dll but nothing changed...
Then I decided to setup OWC11 and it seems to works fine.... even if I don't
authorized it... (is it a normal behaviour ?, shouldn't I be supposed to
autorized it ? )
I can't understand my problem with OWC9 is there some incompatibility with
IIS6 ? Code:

code inside is BLANK) will return a error labeled "The requested resource is
in use. ".
I've tried many things like re-installing IIS 6, allot of things. PLEASE

I migrated an application from NT4 (IIS4) to 2003 (IIS6).
The application only works when the components are registered with regsvr32.
One of the webpages doesn't work-- when I fill the form out and hit submit I
get "compx error '800af10a' Insufficient memory to perform operation.
/submit.asp, line 283"
I've tried going through and changing permissions but haven't had any luck.
I also tried setting the Web Site to use an Application Pool that I created
to run as System Mode but that didn't make any difference.
Everything works when I select "IIS5 Isolation Mode".
Knowing that it works under IIS5 Isolation mode how can I determine what is
causing the message so I can run it under IIS6?

I migrated a VID6 application from Windows NT 4 to Windows 2003 Server (IIS4
to IIS6) which was developed using ASP and VBScript and I now I am getting an
error message as follows:
Microsoft OLE DB Provider for Visual FoxPro error '80004005'
There is not enough memory to complete this operation.
/hinojosa-web/iPD2.asp, line 377
The line mentioned above refers to the execution of a query to generate a
recordset which will be displayed to the user who is requesting data. This
issue does not always happens, it does only after accesing the web site
several times.

Set oVar = Server.CreateObject( "MSWC.PermissionChecker" )
The PermissionChecker component works flawlessly in IIS5.0, but we're migrating to IIS6.0 and it no longer works because IIS6 no longer supports it. Has anybody gotten around this issue?

I've used DynuFTP and am happy with it but now the host server needs upgraded to IIS6 and Win2003. After they did this I get the error that I'm pretty sure is from DynuFTP:
Active Server Pages error 'ASP 0115'
Unexpected error
/cms/Upload.asp
A trappable error (E06D7363) occurred in an external object. The script cannot continue running.
Has anyone run into this? Seems like an IIS6 compatibility issue.

we just upgrade a win2k server to win2k3. First we depromoted it, then we made the upgrade. The webs with ASP worked OK.
Then we made the DCPROMO and promoted it. After restart ASP's won't work.
The message on IE is:
"ya se está utilizando el recurso especificado"
something like "the specified resource is already in use"

Part of the content of one of our web pages uses wingdings and Chr(239)
through Chr(242) (which are little arrow outlines, though that's not really
important.)
It worked just fine in Windows 2000 Server, but now under Server 2003 it
seems that characters above 127 get converted somehow, and our code no
longer produces the desired effect.
Does anyone know how to make it send our content without modification, or
how to encode it in a way that it makes it out to the browser with the
intended character value (as opposed to some thoroughly useless conversion
to a 7 bit value)?

Im trying to find why my hosted server won't maintain session state.
Its not a web farm (not load balanced), its all the same server
An application requires a session to be set and then recalled (like you do
:)
However, since the server software was upgraded from IIS 5 to 6, the working
code no longer works.
(ie - login with session variables but get logged out immediately the page
changes)
Using simple code like <%=session.sessionid%> on the IIS6 server, and
refreshing the page shows a new ID most times - it should be the same id??
Testing on the old server (IIS5) would keep the same session id.
Where do I start looking and what pertinent questions do I need to ask my
host?

I am trying to set a webserver to use French regional settings for testing
ASP pages.
According to http://support.microsoft.com/kb/q306044, for IIS5, this is a
matter of changing the regional settings for the authenticated user, and if
this user does not have a user profile then the default regional settings.
Unfortunately, this does not seem to be working in IIS6, in that I have
change the default user's settings and I am still getting English dates. Can
anyone tell me if this is because the way IIS chooses its settings has
changed for IIS6 or just because I have done something wrong?

I am using traditinal asp in IIS6 and seem to be experiencing memory leaks problems that I did not have or at least did not seem to notice as much when I was running the same code under IIS5.
There may beunclosed connections/recordsets and/or connections/recrodsets that
have not be set = nothing in the code. Two questions
1. Is IIS6 less forgiving of this?
2. If you do not close recordset or connection objects or set them equal to nothing is there some sort of garbage collection going on in asp that will release the memory anyway.

My company is in the process of moving servers and I am one of the developers in charge of making sure it runs smoothly. Currently, we are on a Linux server that runs Chilisoft ASP. We are moving to a 2003 Server with IIS6.Several of our scripts use the recordcount property of recordsets.
On the new server, recordcount seems to be shaky. We have managed to get it working on one of our websites fine, but on another site on the same server it does not. Both sites are configured in the same manner. We did have to add "objConn.CursorLocation = adUseClient" before opening each connection, which made it work for the first site, but adding the same line of code on the other site seems to have no effect.

I have an ASP app that grabs the logon user, and then I use GetObject to query the user's security groups. On a Windows 2000 server running IIS5, this works excellent. I then copied it to a different networks, Windows 2003 server running IIS6, and now I get permission denied on GetObject. How can get around this?

My sessions variables are resetted without any more information from time to time. I am calling /Alive.asp every 5 minutes. (Doesn't really do anything by itself, it is here only to keep alive the sessions) And from time to time, a Session_OnStart is called again ! (And my Session variables are resetted) I've checked this with the AppendToLog in the Session_onStart
- The cookie ASPSESSIONID has not changed
- It's not a session timeout (20minutes)
- There is nothing in the eventlog about pool recycling
(Default settings for this)
Have you any idea ?

We've been using Index Server and IIS4 and the corresponding objects to
search our sites. Everything fine.
Now we have set up a new server running IIS6 and the search results always
return "null" for Characterization, DocSubject and some other properties. I
found out that they were not cached. But turning caching on and initiating a
reindex didn't help either. Code runs fine on IIS4.

I have a problem with our web servers and memory etc.
We have one application pool with a few websites in it and the w3wp.exe is
consuming about 800 mb memory now.
First we had a rule for recycling the application every x minutes or when
it's using more than 600 mb memory but when the recycle is activated the
w3wc.exe process hangs and the cpu usage goes to 100% until we execute an
iisreset.exe.
That's the reason why we disabled all the recycling options and configured
only one worker process for that application.
All the websites in the application pool use the same code, only they have a
different skin.
The website also uses xml/xsl transformations.
Is it normal for an application to push the w3wc.exe process to about 1GB???
If this is the case i really want to know how much memory dedicated hosting
companies need in their webservers :-)
We are storing some information in the application cache, but this is only
for the entire website and not per user... in plain text so the amount of
data would be no greater than 100KB at most.
The application is in classic ASP.
We walked thru the entire code and checked for correctly closing all sql
recordsets, email components etc etc etc...
What is the best approach to find out what is using so much memory and why
the recycle does not work correctly?
