Default web site error "Service Unavailable" for OWA works
in [IIS]
|
From: Allyn on 18 Jul 2007 00:42 We have a Windows 2K3 server running Exchange. When going to the default web page, a browser gets a reaspons "Service Unavailable." However, the OWA site (off the default web page) works. I had a redirection in the default web page, which has worked for a couple of years, but a few months ago everything directly in the default site has stopped working. This server is a DC. I've gone through the various posts. One reference ADFS, which isn't installed. Another posts referenced http://support.microsoft.com/Default.aspx?id=842493, which I followed but to no success. Thanks for any guidance.
From: Ken Schaefer on 18 Jul 2007 01:30 Service Unavailable is a generic error message probably coming from http.sys indicating that the website requested is not available. OWA (from memory) runs in a separate web application pool, so that's why it's probably not affected. Please look in: a) The Windows Event Log and b) the httperr.log file (in c:\windows\system32\logfiles\httperr) and post any relevant error messages that you see in those two logs. Thanks Cheers Ken "Allyn" <Allyn(a)discussions.microsoft.com> wrote in message news:7EB42BD8-8DAA-4906-A32C-5F5DA6100F9E(a)microsoft.com... > We have a Windows 2K3 server running Exchange.

From: Allyn on 18 Jul 2007 02:08 There are two events in the event viewer, and I've tried several fixes on Google to date. Event ID: 2268, Could not load all ISAPI filters for site/service. Therefore startup aborted. Event ID: 2214, The HTTP Filter DLL \\?\C:\IISDebugTools\IISCHAgent.dll failed to load. The data is the error. Regarding the httperr file, here is what is in this since a reboot this evening: #Software: Microsoft HTTP API 1.0 #Version: 1.0 #Date: 2007-07-18 05:18:40 #Fields: date time c-ip c-port s-ip s-port cs-version cs-method cs-uri sc-status s-siteid s-reason s-queuename 2007-07-18 05:18:40 68.15.104.222 1298 172.16.100.11 443 HTTP/1.1 GET /favicon.ico 503 1 AppOffline DefaultAppPool 2007-07-18 05:18:46 68.15.104.222 1297 172.16.100.11 443 HTTP/1.1 GET /favicon.ico 503 1 AppOffline DefaultAppPool 2007-07-18 05:18:46 68.15.104.222 1299 172.16.100.11 443 HTTP/1.1 GET /favicon.ico 503 1 AppOffline DefaultAppPool 2007-07-18 05:18:51 68.15.104.222 1301 172.16.100.11 443 HTTP/1.1 GET /favicon.ico 503 1 AppOffline DefaultAppPool 2007-07-18 05:19:14 68.15.104.222 1302 172.16.100.11 443 HTTP/1.1 POST /exchange/adsne/Drafts/No+Subject.EML/?Cmd=addattach&Embedded=0&Target= 400 1 BadRequest ExchangeApplicationPool 2007-07-18 05:19:14 68.15.104.222 1303 172.16.100.11 443 HTTP/1.1 GET /favicon.ico 503 1 AppOffline DefaultAppPool 2007-07-18 05:19:27 68.15.104.222 1306 172.16.100.11 443 HTTP/1.1 GET /favicon.ico 503 1 AppOffline DefaultAppPool 2007-07-18 05:19:59 68.15.104.222 1302 172.16.100.11 443 HTTP/1.1 POST /exchange/adsne/Drafts/No+Subject.EML/?Cmd=addattach&Embedded=0&Target= 400 1 Connection_Dropped ExchangeApplicationPool I went into Internet Services Manager and saw the DefaultAppPool had terminated to an unspecified error.

From: Ken Schaefer on 18 Jul 2007 02:26 For each of the two events that you are seeing in the Event Log, please open the event. There is a "copy" button (it looks like two pieces of paper). Please press that, and past the entire event details here. Informtion such as "the data is the error" is helpful information (it is usually a hResult that can help tell us whu the filter failred to load). The second thing to check is what ISAPI filters you do have configured for the default web site.

From: Allyn on 18 Jul 2007 02:30 Just for grins (I wish I had a better reason) I elected to remove IISCrashHangAgent from the IIS configuration, and everything works fine. I've rebooted, and the default web site comes right up. The errors are gone from the event viewer and the httperr file as well. Thank you.
