a) Is the World Wide Web Publishing Service started?

b) If nothing is appearing in the IIS Logfiles, then the request is not
getting to IIS, or something is happening to the request when it gets to
IIS. I would suggest the former. Check to ensure you don't have a firewall
enabled (or similar) that's stopping the requests from getting to IIS. Try
using telnet and seeing if you can open a connection to your server on port
80:
telnet>open yourservername 80

If you made a request to OWA and it does not show up in the IIS web logs,
then your request is not making it to the server running IIS, which
indicates a networking issue. Nothing you can do on IIS to fix this sort of
external infrastructure problem.

Now, if you tell me that a user on another machine can get Outlook to
connect to Exchange on this server just fine, yet OWA on IIS from this same
server does NOT work, then we can start looking at other things.

Also, turn off IE's "Show Friendly HTTP Errors" option to report the actual
error page/code (if you see it).

Also, make sure that IIS is actually running and listening on port 80 to
service the HTTP requests for OWA.
netstat -ano   should show what is listening on port 80.
net start W3SVC     should succeed.

But it works until 5:52pm Aug 9.  Nothing changed  (I know famous last
words).
Cannot get pages from inside or outside to inside address or outside
address.

Yes, exactly,  EVERYONE can get to exchange thru Outlook 2003 just fine.
Mail using the OL2k3 client is working without problems.  Only IIS is being
bad.

I did this, restarted IE, still get page unavailable, Cannot
find server or dns error.

netstat shows that port 80 is being listenned on.
I stop w3svc, port 80 not in use for listenning
I start w3svc, it comes up fine, but no pages.

Does "logs" include the windows event log?

Check there for errors that occur when the service is started, and for
errors at the exact moment you try to open the page on another machine.

[ Post a follow-up to this message ]

Yep, checked event logs - nothing.

I DID find a log called httperr on Windows\system32\logfiles

that keeps showing:

2005-08-09 20:02:29 - - - - - - - - - 1_Connections_Refused -
2005-08-09 20:02:39 - - - - - - - - - 1_Connections_Refused -

2005-08-11 13:54:49 - - - - - - - - - 4_Connections_Refused -

I mean hundreds of these starting at the time the web server stopped serving
pages.  So what could cause the web server to stop serving pages and get a
connection refused?   It even happens on the local machine running the iis6

Well, after seeing the Connections_refused error in httperr1.log, I got to
ms and see that it means:

"The kernel nonpagedpool memory has dropped below 20MB and http.sys has
stopped receiving new connections."

from this article:
http://www.microsoft.com/technet/pr...s/remstorg.mspx


My task manager shows kernel non-paged pool at  189952(K) so I am assuming
the error means 200MB

Anyway, now how do I fix it?  I've tried stopping http and https, and w3svc,
with no help.

The machine has 1g of memory and is only a file server and exchange server.

Is this machine running with the /3GB switch (for Exchange).

No, it means 20MB _free_.
The value you see is 189952K _in use_, which seems rather high to me (just
checked on a server here, and it's only 30316K).

The maximum nonpaged pool is 256M on Win2000, on NT4 it was 128M.

Actually there are two separate address ranges of 128MB each.  With the
/3GB switch, one of these is dropped and the maximum falls back to 128MB.
You're obviously above that, so I assume you're not using /3GB ;)

You can try playing around with the Session Manager\Memory Management
registry values, but I don't think it's a good idea.  Increasing the
nonpaged pool size reduces the size left over for the paged pool and system
PTE's, and all of that has to fit in 491MB + 448MB (the sizes of the two
address ranges).
