We can not scan the workstations

We can not scan the workstations

Hello,

We contact with you, because we use Service Desk Plus-MSP version 7.6 and we are making the scanning of workstations on different accounts, but it shows the message us:

 

“Error : No response received from workstation. Probably the workstation might be switched off or does not exist.”

We have checked that the error that it shows us, it has been on computer with Windows 7 Professional of 64 bits.

 

We do ping, we have enabled TCP port 7, we configured the ports RPC and  the settings DCOM, but the problem persists.

 

What should we do to fix it?
 
Regards
