The access to my MS CRM 4.0 from an outside web browser is http://crm.company.org:5555 or if accessing the CRM site from inside my office it is http://company05:5555.
I am trying to set this service up on a computer within the office network.
Since we don't have your credentials for testing, we assume that your CRM is using Windows integrated authentication.
Please try to use the following settings:
Auth Type: Windows Integrated Authentication
Web Service URL: http://crm.company.org:5555/mscrmservices/2007/CrmService.asmx
Username: Your username
Password: Your password
Windows Domain Name: Your Windows Domain Name
If the above configuration does not work, we can try to check it if you give us a read-only credentials (or minimum privilege) to login to your CRM.
