Hi,

We have integrated our portal developed in ASP.NET 2.0 with MS CRM
3.0 using the web services exposed by CRM.

We are able to insert the records successfully in Account and Contact
Entity but while in update code fails with The Request Failed with
HTTP status 401 Unauthorized

We have tried all PreAuthenticated = True, Impersonation = True,
default credential etc....but no Luck.

Kindly, help us in over coming this strange problem.

Thanks & Regards
Bharat Arora

Hi Bharat,

The information you told, are too few telling you something "precious".
I suggest some things, but I don't know is it useful for you,
- you should create crm webservice proxy using wsdl.exe instead of Visual
Studio 2005 add web reference dialog. The difference, wehn you are using
directly Vstudio, the Vstudio builts in automatically the authentication
method. may be it is incompatible.
- the scenes behind might be infrastructural problems. For discovering
authentication problems in IIS, you should use iisdiag (IIS diagnostic
toolkit - free download from Microsoft).
- You must install ms crm into a new website other than your application
lays and unregister aspnet 2.0 scriptmaps before installation. (in 2.0
framework dir run aspnet_regiis.exe -k W3SVC/<crm website id>/ROOT if they
are registered already.
- possibly may have problems with website and AD integration. before MS CRM
installation you can create a website for ms crm, and set explicitly NTLM AND
Kerberos authentication on the website. Defaultly all website uses implicit
authentication which sometimes not enough. Use adsutil.vbs for querying and
setting NTLM and Kerberos in your website
- You must use another app pool in your aspnet 2.0 website than CRMAppPool
- If you have Windows 2003 R2 server, you must read the new IIS security
settings and facilities in Technet pages
- Please try to get information in the MS CRM Deployment list as well,
because your problem might have infrastructural causes.

Good or solve problems seemed with the VS.NET 2005 with the following
steps:

You must create a new alone POOL for the application in vs.net 2005
that uds have created.

On the other hand, I also trataria of placing
OService. Credentials = new System. Net. NetworkCredential
("administrator", "pass@word1", "crm");

Slightly this way in the credentials for fault, it tries with the user
that your using these.

Agree yourself that the MSCRM runs under Framework 1.1 and the
application throw in VS.ET 2005 this one in 2.0
