When i try to open Microsoft Dynamics AX client from the local system am getting a pop window like “Microsoft Dynamics AX client has topped working” with 2 options
Check online for a solution and close the program.
Is this every time you try to open the client on that machine? I imagine the client configuration to the AX server is setup properly and it was working initially?
If so you could try this: in Windows Explorer go to C:\Documents and Settings%USERNAME%\Local Settings\Application Data and locate the file(s) that are named ax_{GUID}.auc. Delete those and restart the client.
