CRM 4.0 - IFD- HTTP Error 401.1 - Unauthorized: Access is denied
Mark Smyth
file. External access to the CRM works correctly but when trying to access
CRM from the LAN where the CRM server is contained we are prompted for a
username and password 3 times before this 401.1 error.
What this also means is that the CRM Email router cannot connect to the
deployment.
Checking the settings of CRM with the IFD tool shows all to be correct. We
have another live environment and a test environment that works, both were
installed normally and then used the IFD to change the settings.
We used the xml file to deploy CRM as the IFD was not the recommended
solution at the time.
Has anyone else seen this and got a solution. (Please do not recommend any
hotfixes unless you know they will work as we are very current on what
hotfixes their are).
Yes, all the group memberships are correct as far as PrivUsers etc.

the web site properties for Microsoft CRM, make sure that Windows Integrated
Authentication is enabled, along with Anonymous access.

From what I can see this is not a permissions problem either with settings
in IIS or the physical permissions on the files and folders. I have compared
them with a working environment.

whether user credentials are entered or not? Is the 401.1 error the "page
cannot be displayed" error with the number at the bottom, or is it only one
line of text at the top of the page? Are there any other sites on that
server that use Windows authentication? Does this happen when you are on the
CRM server and use localhost?

resolved it. It had to do with the IP address range that I entered was
incorrect in the IFD tool. Once I corrected the IP address range of the
"private / internal" CRM address range it started to work. Give that a go and
let me know if it works.

Hei Richard
We have the same problem, but in our case is it only one line of text
at the top of the page.

I'm also getting this error. Although I tick the "remember my password" in
the login window it keeps asking for the password like 20 times before
displaying the error. Sometimes some components are displaye, like the
toolbar, while the rest are replaced witht the error message.
I only get this error when trying to access over the internet from a pc that
is on another domain. I modified the IE settings to ask for username/password
every time but this didn't fix the problem.
I think it's a client problem, can anyone help please.
Thanks,

If setting Anonymous access doesn't work, I'd recommend that you try
installing and running the IIS Diagnostics utility
(http://www.microsoft.com/downloads/details.aspx?familyid=9bfa49bc-376b-4a54-95aa-73c9156706e7&displaylang=en)
on the CRM Server. If the diagnostics results for authentication shows that
keepalives are disabled on the site, install a copy of the IIS Resource Kit
on the server and use the Metabase Explorer to check the "AllowKeepAlive"
setting on the CRM website. That needs to be set to 1 or Kerberos/NTLM
integrated authentication won't work (Remember, IE always tries anonymous
first before it tries to authenticate . Without a keepalive, IE will create
a new HTTP/TCP session and use anonymous again and again until it times out.)
While you are in the Metabase Explorer, also look and make sure that
"NTAuthenticationProviders" is set to "Negotiate,NTLM". If the Negotiate
part isn't there, IIS won't accept Kerberos. Make sure you configure the web
site to allow editing of the metabase before you use Metabase Explorer to
change anything.
I had literally tried everything before I came across the IIS Diagnostics
Toolkit (down to packet tracing which clued me into the problem). This is a
great tool for troubleshooting authentication and IIS configuration problems.
