HTTP 500 error 0x800700aa loading .asp pages RRS feed

    ISAPI_START 21:01:40.516
    CALL_ISAPI_EXTENSION DllName="C:\Windows\system32\inetsrv\asp.dll" 21:01:40.516

    This is the failed request tracking entry that points to the problem (I think). Although, I don't know how to resolve "The requested resource is in use."
    This happens for every .asp page -- all .htm pages are fine. This application was working at one point, but something happened recently to prevent it. I don't know what.

    Here is the entry in the IIS log that pertains to this request:
    #Software: Microsoft Internet Information Services 7.0
    #Version: 1.0
    #Date: 2007-11-13 21:01:40

    Things I tried and checked:

    • 32 bit apps enabled in IIS
    • allocated app to classic .net pool
    • tried hitting a basic/stripped ASP page to test
    • reinstalled IIS
    • reinstalled ASP
    • checked all permissions for IUSR in application directory and in inetsvr directory
    • tried using an administrator account instead of IUSR
    • UAC is off
    • ran regsvr32 on asp.dll and other related DLLs
    • enabled the tracing and got that message above
    • system and application event logs have no related entries
    • unplugged pc, threw across room, plugged back in -- same error

    My system:

    • IIS 7
    • Vista Ultimate x64
    • 2gb RAM
    • Athlon 64

    Can anyone tell me what I should look for to correct this? Thanks in advance.

    Edit: procmon shows this when I hit the page -- it's all I can dig up that might have something to do with this:

    Ok I think I fixed it. After I followed the followign steps it worked for me.

    In IIS Manager choose View Application Pools
    then choose Set Application Pool Defaults.
    Then under Process Model set Identity to LocalSystem.


    Let me know if it works

    A good toss always makes you feel better. :) You've tried quite a bit, thanks for posting.  I don't have an Vista 64 bit box handy, can you check ISAPI and CGI restrictions and make sure ASP is enabled.  That is one thing that stands out right now.

  • User-799039264 posted

    ASP is indeed "allowed" in the restrictions. I guess I forgot to mention that one.

    This is not something we have seen and there seems to be no way to get to the bottom of this without debugging it - so your options are

    a) Come up with repro steps which can help us repro this problem in-house

    b) call up microsoft support and ultimately get someone from support to debug the problem

    c) reinstall and (hopefully) the problem goes away

    I am at wit's end. I'm rebuilding the machine. It was working before and I don't know why it won't now. For me, every ASP page fails. Even a page that has one line of code in it for testing. Extremely frustrating.

  • User-1012857663 posted

    Yes...I am runnign through the same problem. This was working a couple weeks ago no problem...every ASP page now gives me that error. Htm files are ok though. I tried different directories and the same problem. Just so frustrating when you know something worked a couple days ago and now it does not. Vista is evil. 8-)

    Note that you would probably not want to run the application pool as LocalSystem in a production environment, this would increase your exposure to any security issue - this indicates that there was something that NetworkService could not get permission for, surprised that you did not see anything in the process-monitor logs.

  • User-799039264 posted

    Setting this up with Vista has been absolutely painful. I made it work for local testing purposes and it's now using SpecificUser instead of NetworkService or LocalSystem so that I can specify an administrator account on the machine. If I don't do this, none of my database calls work.

    I couldn't get SQL Server 2005 to install on Vista either and have VMware running XP x64 so I can connect to it. The setup is nuts, but it works. My production environment is third-party hosted and does not involve Vista... so none of this is an issue.

    I have the same problem, but after changing the identity of the application pool from "NetworkService" to "LocalSystem", all ASP pages start working, but any asp application that uses the Application, Session or Server objects now fail (and that is pretty much all ASP applications).

     I now get an error like this:

    "error '8002801d'
    /Default.asp, line 4"

     Where on that line is either code using Application, Session or a Server object. All other code above that works. These pages used to work about a week ago. I did not change anything in the ASP files or anything else. Please help, I have tried everything, including uninstalling and reinstalling IIS and ASP. It still does not work.

    Well this is the first time I see 'resource in use' for IIS 7 :)

    If it works via LocalSystem, then I suggest you check if NetworkService has read&execute permission for asp.dll. If it is then need to figure out where networkservice having access issue. Get Procmon from MS and trace it.

    I have a similar problem.  I set up and was working and what I did was I run a test website in visual studio 2008 and then I couldnt view classic asp pages again .  generating error 500 .  Tracing gives me  ErrorCode: 0x800700aa.  It also tells me that  Execute_request_handler: The requested  resource is in use(0x800700aa)  I checked and found out that asp.dll was not set up but can also not be found in the resources available to add.  Strange.  I am using vista business.

     I am having a nearly identical problem. My classic asp pages work until I use one of the Application, session or server objects, then I get the '8002901d' error as well. Checking Event Viewer / Windows Logs / Application, I have the following entry each time the page is executed

    "Error: The Template Persistent Cache initialization failed for Application Pool 'ASP.NET 1.1' because of the following error: Could not create a Disk Cache Sub-directory for the Application Pool. The data may have additional error codes.."

    These asp pages worked fine until I installed Vista Service Pack 1, then all fail. I've already lost the restore point to before SP1 was installed, and uninstalling SP1 did not resolve. I've tried every suggestion I could find on the web for IIS 7 setup, but nothing so far has fixed this for me.

    HOLY CRAP!!! 

    I've been trying to resolve this problem for months. I finally gave up on classic ASP on my Vista machine and kept another older box around specifically to maintain 1 application. I just came across this post last night and now I'm off and running.

    Can't thank you enough, alopez2007. I had to register here just to give you a shout... really... thanks a bunch!

    This is late but here is an instance of the problem:

    One of our PSS guys just troubleshooted this issue with a customer. Here is the reason.

    The issue was that McAffee  overwrote the entry  below for Vbscript.dll with its own entry but this was not removed when McAfee was uninstalled.   <?xml:namespace prefix = o ns = "urn:schemas-microsoft-com:office:office" /><o:p></o:p><o:p> </o:p><o:p> </o:p>HKEY_LOCAL_MACHINE\SOFTWARE\Classes\CLSID\{B54F3741-5B07-11cf-A4B0-00AA004A55E8}\InprocServer32<o:p></o:p>    (Default)    REG_SZ    C:\Program Files\McAfee\VirusScan\scriptsn.dll<o:p></o:p>

    Hope this helps

     Replace that registry key with C:\Windows\system32\vbscript.dll to fix the issue. It's confirmed in my case as well.

    what if my registry entry has oleaut32.dll for InprocServer32. Should that be updated to vbscript.dll? I have other pools servicing asp pages fine, just this classic pool is failing so i am hesitant to make a registry change that could break other applications/pools. Thanks.

    Saddly yes. I am unable to reinstall as production currently running under this pool aspx pages work fine. I have tried/verified the registry entry as stated in thread. Swapped the users for the pool, from ApplicationPoolIdentity to LocalSystem to even one of our domain administrators. Hesitant, but today going to try taking a backup using the appcmd and then running the application from a Integrated Managed Pipeline Mode rather then Classic and see what works/breaks. We have other pools on the box that are in this Integrated Mode that have no issues. Not sure why this one is different. Original person who set-up has moved on. Let me know if you have any bright ideas. Thanks!

    To clarify, aspx works fine, but asp pages are getting the resource is in use issue. Seems to be the type of page, cause i have made my test asp pages be simply just html and they aren't working. Thanks!

  • User-1725224607 posted
    Moved the application to a different pool which has asp working and that didn't resolve the problem. Didn't `convert` the application using appcmd. Just moved it. So not sure if that made a difference. Good not it didn't break anything either. Thanks

    So looks like when i comment out <authentication mode="Windows" /> and change the pool identity to localsystem the asp code starts working. The aspx code then fails. Any one see a way to have my cake and eat it too? What is this authentication mode and how can i use it so both asp and aspx pages are happy :)
    Friday, January 7, 2011 3:31 PM

    should say comment out the line that has: authentication mode="Windows"

    Somehow, somewhere, the access permissions were messed up. Forget how you can reset all to the default setup, but here's some info on the account/security changes. http://learn.iis.net/page.aspx/140/understanding-built-in-user-and-group-accounts-in-iis-7/

    it is not recommended to run as localsystem unless it is necessary, you should use back the default app pool id, and then use procmon to trace the asp related error, I mean it should be permission related and procmon should be able to trace it.
