TCP 3 Way Handshake - retranmission

I have a issue with a client copying data from a server (Windows is the OS)

I did a capture and noticed a large number of TCP retranmissions

This also includes the 3 way hand shake with retranmissions

client sends syn - 5 retranmissions is done of this packet

server send ack to the syn - 3 retranmissions done of this packet

client ack - 3 retranmissions done

TCP Retranmissions occurs through out the copy of the file and in the end Windows gives us with an error copying the file

What could be the root cause of this packet loss or some kind of assymetric routing

The round trip between in the handshake is 20 milliseconds
