TwinCAT is not finding EtherCAT. WHY?

I am not getting why twinCAT is not finding EtherCAT but it ialways displaying RT-ethernet. I also followed the steps frow the beckhoof website, finally in command prompt i am getting the msg as"The requested service has already been  started"  but still it's showing RT-Ethernet.  I have tried it in both windows xp & windows 7 but i am facing the same problem.

Has the EEPROM device on the EtherCat slave been programmed with the ESI information? If this file hasn't been downloaded then the slave will come up as RT-Ethernet device. The ESI file can be downloaded to the drive via TwinCAT.
