ASP on IIS was working, suddenly it ain't!

Hi,
I'm a complete IIS newbie. I installed IIS 5.1 on XP Pro the other day, ran iisstart.asp and it was working fine. Didn't do anything to the configuration, just read through a bit of the documentation.

I came back today and suddenly it's not working. I open http://localhost/ and get a 500 Internal Server Error

or

"Server Application Error. The server has encountered an error while loading an application during the processing of your request. Please refer to the event log for more detail information. Please contact the server administrator for assistance."

No ASP pages seem to be working. I created a flat HTML file and that loaded ok, but no ASP.

Looking at the Application Event Viewer there are a lot of COM+ errors, is that related?

As I said, I'm a complete newbie and have no clue why this is happening. As I didn't change any settings I don't see why it would just stop working. I've fiddled around in the IIS Control Panel and reinstalled IIS but to no avail.

Can anybody help me?

Thanks in advance.

Some more info on this. Having checked the Event Log there seem to be two issues when I try to load an ASP page in IIS:

----------------------

Warning
The server failed to load application '/LM/W3SVC/1/ROOT'. The error was 'The server process could not be started because the configured identity is incorrect. Check the username and password.
'.

AND

Error
DCOM got error "Logon failure: unknown user name or bad password. " and was unable to logon .\IWAM_MYCOMPUTERNAME in order to run the server:
{3D14228D-FBE1-11D0-995D-00C04FD919C1}

Does this shed any more light on the problem?

Thanks Doug.

I ran synciwam.vbs using wscript and cscript and got the following:

"Error: 1AD: ActiveX component can't create object"

At the bottom of that page you linked to, it gives instructions for opening up Component Services > Computers > My Computer > COM+ Applications

I tried this and when I click on Computers to expand that, the entire Component Services window disappears! Surely that's not normal. I can't get to My Computers > COM+ Applications

Makes me think something more serious has happened but I have no idea what to do....

I have had similar problem before...

I stopped the antivirus restart the machine the asp worked

Unfortunately it turned out to be a more serious problem for me - COM+ was damaged in some way and was spitting out all sorts of errors in the event log.

Had to do a full Windows reinstall to sort it out. I think the problem originated when I accidently knocked the plug for the computer out of the wall...not advisable!

If your web server is exposed to the internet via a full-time connection you need to keep all your windows updates current. Unpatched IIS's can be hacked, you may recall the Nimda/Code Red attack of a few months ago.

Windows update is the first thing I do everytime I reinstall the OS. Thanks.

Greetings,

I'm a new member. This is my first post.

I ran into the exact same problems as Niall on this issue with XP and IIS 5.1. I'm at the step where Niall was on February 4th, 2004, 06:31 AM.

i.e. I tried running synciwam.vbs using wscript and cscript and got the following:

"Error: 1AD: ActiveX component can't create object"

My Component Services crashes in the windows program just it did for Niall.

Is there another workaround besides reloading Win XP?

Having the same problem also. IIS not displaying .asp page. When I try to access "Component Services" , it dissapears. Event Viewer show a bunch of errors on
"COM+ System Application service terminated unexpectedly"
and W3SVC warnings.

Anyone know a way to fix this, I dont want to go through Installing winXP
