Question

Iphone and SBS 2003 connection failed

Asked by: shaun1610

Looking for much sort after help!

Problem is that i cannot connect a iphone 3g with our sbs 2003 server and running out of ideas!

i can access the following from the internet (and iphone web browser) via a certificate procured with comodo:
https://mail.<servername>.co.uk/exchange
https://mail.<servername>.co.uk/oma

Active sync is enabled in exchange and for the users.

When i try to connect with the following settings, I get an Exchange account verification failed:

Email: <name>@<servername.co.uk
Server: mail.<servername>.co.uk
Domain: <domain>
Username: <username>
Password: <password>

The DNS settings all appear to be correct (initially I did not have an A record for <servername.co.uk> although always had one for mail.<servername>.co.uk.

In addition, i just ran the https://www.testexchangeconnectivity.com/ utility and the failures were:

Certificate name validation failed
Attempting to resolve the host name autodiscover.<companyname>.co.uk in DNS - The Host could not be resolved.

This is strange as the certificate is fine for mail.<companyname>.co.uk as proven via the iphone web browser and the host name is set up correctly, the a host points to the correct server from a nslookup????

Really appreciate any ideas / advice - but I'm not most technical!!

Thanks in advance,
Shaun

Do you have ports 443 and 993 (TLS) open through your firewall?

 

by: shaun1610Posted on 2009-11-06 at 05:01:36ID: 25758699

Hi there, yes both. 443 is proven via the correct https:\\mail.<servername>.co.uk  access

 

by: ajwukPosted on 2009-11-06 at 05:08:59ID: 25758735

Does the account logon name in AD match the malibox alias (Exchange General tab for an AD user account)? This can cause account verification failures for mobile devices/IMAP etc.

 

by: shaun1610Posted on 2009-11-06 at 05:17:26ID: 25758788

Yes exactly

 

by: ajwukPosted on 2009-11-06 at 05:22:12ID: 25758808

It may be something funny with forms based authentication then. Try turning this off in Exchange.

Exchange System Manager... Servers > Server Name > Protocols > HTTP > Exchange Virtual Directory (properties).

Uncheck "Enable Forms Based Authentication" See attached.

 

by: shaun1610Posted on 2009-11-06 at 05:29:04ID: 25758849

Sorry no joy with that. Do you think the issues relates to the below..

In addition, i just ran the https://www.testexchangeconnectivity.com/ utility and the failures were:

Certificate name validation failed
Attempting to resolve the host name autodiscover.<companyname>.co.uk in DNS - The Host could not be resolved.

This is strange as the certificate is fine for mail.<companyname>.co.uk as proven via the iphone web browser and the host name is set up correctly, the a host points to the correct server from a nslookup????

 

by: ajwukPosted on 2009-11-06 at 05:34:40ID: 25758886

Do you get the DNS resolution failure while on GPRS/3G? It's not connected to an internal wireless AP or something is it?

BTW... did you restart IIS after making that change?

 

by: shaun1610Posted on 2009-11-06 at 05:45:54ID: 25758979

yes restarted and connection from iPhone still fails. Also, turned off the wifi on the iPhone and tried connecting and again failed. This is a nightmare!!!

 

by: shaun1610Posted on 2009-11-06 at 05:49:16ID: 25759005

Could it be getting confused with SSLs? as I have a ssl for mail.<companyname>.co.uk but not one for <companyname>.co.uk ?

Don't forget I'm using SBS 2003 and default web site with original configuration

 

by: SatyaPathakPosted on 2009-11-06 at 07:27:12ID: 25759892

Please find IIS authentication type and the SSL requirement for Ex 2003.

2) Exadmin : Integrated                                    NO SSL
3) Exchweb : Annonymous                              NO SSL
4) Exchange: Basic                                        SSL Optional
5) RPC     : Basic                                        SSL Required
6) OMA     : Basic                                       SSL Optional
7) Public  : Basic+Integrated                         SSL Optional

Hi there Satya,

This was useful in the setup. I implemented this and ran the tests and the results are below. Unfortunately these are the same as when i previously ran the tests + iPhone still would not connect with connection failure. Out of interest should I be using the domain details in the IIS settings you listed? and also, we using the domain on the IIS and iPhone should I be using <domainname> or <domainname>.local ?

feedback from exchange remote connectivity analyzer
Certificate name validation failed
Attempting to resolve the host name autodiscover.<companyname>.co.uk in DNS - The Host could not be resolved.

help appreciated

 

by: shaun1610Posted on 2009-11-06 at 09:49:34ID: 25761281

I have made some changes and re run the connectivity analyser and now only get one error:

Attempting to Ping RPC Proxy mail.sterlingservices.co.uk
  Cannot ping RPC Proxy
   Additional Details
  A Web Exception occurred because an HTTP 401 - Unauthorized response was received from IIS6  
 

Any advice here?
