Solution:
1.First thing to check is whether the business connector on your IIS machine is set up and pointing to the correct AOS.
2.Check Ax Client configuration for business connection .
3. Open Dynamics AX, Go to AOT->Classes->SysDevelopmentProxy and compile it .

4 Verify the following task.
The Business Connector proxy exists in Active Directory.
The Business Connector is a member of the dbcreator role in SQL Server.
The Business Connector proxy is a member of the Performance Monitor Users,
Power Users, IIS_WPG, and WSS_WPG Windows groups.
The IIS application pool identity for your SharePoint 80 site uses the
Business Connector proxy (see “Configure IIS for SharePoint Services and Enterprise portal”
in this white paper).
You are a member of the Admin group in Microsoft Dynamics AX and a member
of the Administrators group on the server.

5.Full compile AOT in last

6.Check for domain setting for bcproxy account.
its should be never expired password type account.

7. Install .net Framework 2.0,3.5,4.0 etc.

8.Uncheck  the Anonymous user of "IIS \ Directory Security \ Authentication and access control
"Add the BCProxy user to the local Administration group on the IIS server.
Then restart IIS and AX.
