SMTP - Fully qualified domain name

[PVK_Labview]

Hi,

I have a simple SMTP vi, from which I could able to send an Email from my PC but not able to send an EMail using the same program from my colleague's PC. 

The error from the Putty states that there is no fully qualified domain name receiving. 

But when I compare the network settings of mine and colleague, everything looks similar including domain.

Kindly help me on what should I look into. 

Note: I am using Windows 10.... My colleague using Windows 7

Thanks in advance

AFAIK this message is about the email addresses you specified, not the network settings.

Are you sending to and from the same addresses on both PCs?

I used my company outgoing SMTP server. 

I used my work Email to send to my Gmail email and it worked and also I could able to send to all my colleagues from my PC. I have attached my vi also.

But I dont understand why the same program not working in my colleague's PC!!!
