Problems connecting to CRM web service

TheMSsForum.com: The Microsoft Software Forum

Hello Everyone,

I'm writing a tool to push data into CRM through the web service. However,
the CRM server is on a different domain. Running into problems with
authentication.

Code as follows:

CrmService service = new CrmService();
service.Url = "http://192.168.189.135/MSCRMServices/2006/CrmService.asmx";
service.Credentials = new
System.Net.NetworkCredential("administrator","password","domain");

service.PreAuthenticate = true;

etc ...

Originally, when I didn't have the "service.url" line my first call to the
CRM service came back with Logon Failure message. After reading the
newsgroups I added the URL and now I can make "1" call successfully.

All additional calls will result in the same Logon Failure message.

Any ideas?

Hi Michael,

Try service.PreAuthenticate = false;

Or omit the complete line. While recommended by Microsoft in the beginning,
it is now known to cause problems.

Actually I tried both of those ... same thing

I've noticed that after the first call the credential values are reset to
empty which leads me to think it's a caching issue?

any thoughts.
