From CA technical Hotline I've got an email with some missing DLL's attached.
Copying these into the ITM directory and rebooting the server fixed the problem. - Error: 0x8004011d - See ME266312, ME282964, ME821889, ME822579, and ME896703.
The server network card had 100 full duplex and the switch port 100 half duplex.
The switch port was changed to 100 full duplex and Autonegotiate disabled and all is workking fine after without any reboot.
