Hi,

The process ID may be changed because windows will assign a unique process
ID to the w3wp.exe when it is created. From the troubleshooting result, I
think the account "network service" of your worker process should be the
cause for this issue. This account is a very weak account set to the worker
process of your site (the worker process is also called application pool
for your web site). This IIS article introduce the detailed information for
you on this IIS built-in accounts and other accounts:

For troubleshooting, I'd suggest you could specify the Local service/Local
system to the worker process which will give your worker
process(application pool) a very high privilege account to perform the
service which may resolve this issue. The article will introduce the
detailed configuration steps:

Please feel free to let me know if you have any further question on this
matter.

I changed the worker process in the Default Application Pool to run as Local
service and I am still getting the Service Unavailable Error.
I have also installed SP1 on the Windows 2003 Server. Please let me know if
there is anything else I can check.

Thanks,

Hi,

Many causes may stop the worker process and IIS will report "Service
Unavailable". I'd suggest please check the event viewer to see whether any
error message is recorded there. This is a must-step for us on this
troubleshooting.

Furthemore, there is one kb article published for one cause which may be
just yours:
842493 You receive a "Service Unavailable" error message when you browse an
IIS
http://support.microsoft.com/?id=842493

In addition, if the kb article can't resolve this issue for you, please
give me detailed information about your scenario, for example the site is
running ASP/ASP.net, any error message in the event viewer etc. The more,
the better to let me understand this problem. I will research for you on
this issue then.

Look forward to your update!
