ASP.Net hanging

[Marty McDonald]

For some reason, I can't run any ASP.Net apps on my machine. I can't open
them in VS.Net either, it hangs while trying to open a web project.
Non-asp.Net apps work, so I don't think the problem is IIS. I've restarted
my machine, still the problem persists. Everything was fine for several
months. Any ideas?
I'm using...
VS2003
Win2000 Professional

Hi Marty,

From your description, you found that you can't run any ASP.NET web
applications on your machine , also unable to open them in VS.NET yes?

As for this problem, I'd like to confirm some further things on it:
1. Since you mentioned that everything works well for several months,then
do you remember there is any new changes or updates on this machine which
may cause this issue?

2.Have you tried creating a virutal directory(configure as an application)
and put a very simple asp.net web application in it. And then visit the
page in the simple app from IE to see whether it'll hang. (Also, you can
also try visiting a simple classic ASP page to see whether asp page will
suffer the same problem)

3.If the problem is specified to ASP.NET, I think we'd like to do some
further research. But I think you can try resintall ASP.NET via the
"aspnet_regiis -i" command in the vs.net command prompt. Here is the
reference on ASP.NET IIS Registration tool in MSDN:
#ASP.NET IIS Registration Tool (Aspnet_regiis.exe)
http://msdn.microsoft.com/library/en...etiisregistrat
iontoolaspnet_regiisexe.asp?frame=true

Please check out the above items. Also, you can perform some other steps so
as to isolate the problem. If you have any new findings, please feel free
to post here. Thanks.

For item #1, there were no updates. For item #2, I did try other apps, they
did not work either. I tried item #3, and now everything works fine!
Thanks for the help!

Just for everyone's information... Here is a little more detail on exactly
what happened:
Yesterday while working on an ASP.Net app, I wrote code in global.asax for
the app, and I accidentally wrote an infinite "while" loop. So I stopped
the app. After that point everything stopped working, even after restart.
I don't think that would have caused my trouble, but FYI in case people are
interested.

I spoke too soon! At first, # 3 worked for me. Now, the problem is back.
I'm working to check if any updates were applied to our machines yesterday.
But I'm open to other ideas.

[Marty McDonald]

OK ! Now I have really solved the problem!
Whenever you simply open a project in Visual Studio.Net, an application
error is raised. I don't know why that happens. But this causes any code
in "Application_Error" of global.asax to be executed. In my case,
Application_Error had an infinite "while" loop. This explains why my
aspnet_wp.exe process used 99% of CPU. It explains why my other ASP.Net
apps (but non-ASP.Net were OK) would also hang after trying to open that
first app.

To solve the problem, I went to the bin of my app and deleted the dll which
contains my Application_Error handling code. Then, I was able to open the
app with Visual Studio.Net without problems. I altered by "while" loop so
that it would perform properly. Now, everything is OK.
