Awesome! I don't normally leave comments, but this just saved me too much time not to voice my appreciation. Well Done.

I thought I should add to Ravi's problem with McAfee Virus scan.. This problems also occurs when Norton AntiVirus Auto Protect is enabled. So, when installing IIS remember to switch your virus scanner OFF!

So you got the same error again?

I was getting all of the above. However my event log also showed that MSDTC was not starting up. My fix script was as follows: :: repair MSDTC cd c:\windows\system32\ msdtc -uninstall msdtc -install msdtc -resetlog :: repair IIS Package cd c:\windows\system32\inetsrv rundll32 wamreg.dll, CreateIISPackage regsvr32 asptxn.dll IISRESET Ran in under a minute and worked like a charm. This was my first time using ASP on this XPSP2 box, so it may never have been working. The MSDTC errors go way back in my log. I cannot provide any insight as to the all important when did it started. Root cause(s) remain unknown...

Success!!! Here is what I found on my HP dv8000z. It looks like the MSDTC service was never installed. All I did was: uninstall IIS. run msdtc.exe -install run msdtc.exe -resetlog start msdtc service install iis run aspnet_regiis -i In IE I type /localhost and get the welcome page. I start VS, create a C# Web App that defaults to /localhost/WebApplication1 and I go back to IE /localhost/WebApplication1/WebForm1.aspx and it works. Thanks all for all the info. Because this is showing up on the HP boxes, I suspect they just neglected to install MSDTC service when they set the boxes up. Anyway, I hope that helps someone else. I was anticipating a long afternoon but didn't have to edit the registry at all and it took about 15 mins. Good luck all. Frank

Thanks Ray for sharing your solution.

I had a slightly different problem. My ASP just would not execute...no error messages to lead me on, the page just loaded forever. I tried all the fixes noted above, but it still did not work. I even reinstalled with McAfee disabled and did all the fixes again. By chance I picked up a tip through another forum that my GLOBAL.ASA file could be the problem, so I renamed it and WHAM, the ASP ran like a dream! However, that was not the end of my misery because no database access was possible without GLOBAL.ASA, so I continued my research and discovered that the Function FrontPage_FileExists(fspath) was the guilty party. I modified it as follows: Function FrontPage_FileExists(fspath) On Error Resume Next FrontPage_FileExists = False set fs = CreateObject("Scripting.FileSystemObject") 'begin of replacement part if (fs.FileExists(fspath)) then FrontPage_FileExists = True end if 'end of replacement part 'begin of deleted part ' Err.Clear ' set istream = fs.OpenTextFile(fspath) ' if Err.Number = 0 then ' FrontPage_FileExists = True ' istream.Close ' end if ' set istream = Nothing 'end of deleted part set fs = Nothing End Function Again, that was not the complete solution as I got an ODBC error as follows: Microsoft OLE DB Provider for ODBC Drivers error '80004005' [Microsoft][ODBC Driver Manager]Data source name not found and no default driver specified. The solution to that is too long to describe here, but you can find it at: http://support.microsoft.com/kb/306345/EN-US/ After doing what they told me I restarted the IIS using IISRESET and I was SOLVED!! I hope this helps somebody as it is invaluable information that can take days to find...

Unwilling ASP'

Ray — Tue, 12 Sep 2006 21:04:25 GMT

My problem is that my ASP pages just will not execute on XP Pro...no error messages or anything, they just freeze up and do nothing. It's the most frustrating thing I have ever encountered!!! I disabled McAfee, uninstalled and reinstalled, ran all the tips above (no errors), set security permissions, did the works. Pure HTML works fine, but when I load an ASP page the browser loads forever...a permanent FREEZE with no error messages. Is there somebody who can shed some light on this behaviour? Please... Ray

Thansk for the great tip. I ran the cited KB and dll commands in the top post and it FINALLY works after 2 days of searching for the answer.

I don't know what is loaded with dv8000z. is it XP Pro, are you having the 'class not registered' error msgs or ? have you install IIS ?
