Hello,I have deployed CRM 4 list Web part on our SharePoint server, when I modify the web part, I enter the CRM server name (ex. http://CRMServer ), then when i enter the username (domain\username) and password, I get an error message (Your credentials are not valid or no such user exists in Microsoft Dynamics CRM. Sign in with correct credentials or contact your CRM administrator.) The Dynamics CRM is installed on a different server than the SharePoint server. Has anyone, encountered this issue before?? What's the solution?

Hello Andre,Thanks for your reply,I have done the steps listed in the article, but no user the problem still appears. The authentication used on the SharePoint server is NTLM. The CRM Server is on a different subnet, does this has something to do with it?
