File transfer hangs (not one byte sent)

I have an FTP site running on my server that has some HTML files. I can use
IE to navigate to the FTP directory using the FTP directory URL, and it
successfully shows me a list of files. But if I try to fetch one of the .htm
files over this FTP connection, the server just hangs. I checked the
security on the files, everything is fine.

I also have a client who is relying on me to host a very important web site
that Fortune 100 companies participate in, as an emergency hosting because
the shared web host we were relying on before was overloaded. This client's
web site is on the same server as my FTP server in the paragraph above. So
here, the same hanging problem is occurring with some of the .aspx files on
this site. I developed the site, and I am certain that there are no ASP.NET
infinite loops, because we've tried rebooting the server and sometimes
afterwords it will still hang but after a bit sometimes it will load the
page.

So both HTTP and FTP are suffering from IIS hanging sometimes on individual
files (always on FTP, and sometimes on HTTP).

I have the server right here, like four feet away from me. It is not a
network issue.

Server's running Windows Server 2003 Standard.

Any ideas?

Thanks,
Jon

Use IISState to look at the inetinfo.exe process when FTP hangs and post the
log here.

If you are running IIS6 in "IIS5 Compatibility Mode" (such as from an
upgrade or intentional configuration), then use IIS State to target either
inetinfo.exe for Low Isolation apps, or specific dllhost.exe for Medium/High
Isolation apps, and post the log here. If running IIS6 in native Worker
Process Isolation Mode (clean install or intentional configuration), then
use IIS State to target the w3wp.exe serving the particular App Pool that
the hanging application is using.

"Hanging" is a pretty generic phenomenon with arbitrary cause (infinite loop
in user code is one cause, but so is network timeout), so more info need to
be gathered with IIS State during the "hang" to help determine the root
cause. Often, it isn't exactly IIS that is hanging -- IIS is usually a
victim since it hosts and runs other code which is hanging. It's like
saying "Windows crashes" when the DVD player running on Windows happens to
crash.
