CRM 4 Outlook Client Lost Connection Problem…

crosspost from http://blogs.msdn.com/rextang

Most of my testing CRM 4 environment were built upon Windows 2008 Server / IIS7 (both 32bit and 64bit) . The server and outlook client installation works fine without problems. started from this week I am making prototyping env. using Windows 2003 Server R2 with IIS6 and after done the installation, the Outlook client kept telling me “Lost Connection to CRM Server” popup messages in the notification area of Vista. the message said

“Unable to Connect. Lost Connection to Microsoft Dynamics CRM. Microsoft Dynamics CRM will restore the connection when possible. To stop retrying, right-click and select Sign Out”.

had a searching and found this thread about the solution. basically it seems that the outlook client agent just can not have access to CRM web server with proper permissions. by enabling CRM Website with anonymous acess right (via IIS management console). the annoying popup message disappeared. problem solved.

wondering if enabling annonymous access will affect the security of the CRM site, but since trying access from other computer using IE the form authentication poped out correctly, should be no problems doing settings in this way.

also wondering why in IIS7 there was no problems like this…
