TCPIP Delay

Points of My Scenario
1. I am admin of a Windows domain (Server 2003 AD)
2. Member servers run Server 2003 or Server 2008 R2
3. One of my 2008 R2 member servers consistently shows delayed response contacting systems: When I ping a host for the 1st time from this server, I get one "Reply from <itself>: destination host unreachable", followed by 3 proper replies.
4. This server periodically sends groups of files to another system, but the 1st file in the group always gets dropped (just like the 1st ICMP/ping packet).
QUESTION: How do I stop this behavior (first data packet dropped)?

ipconfig /flushdns

Verify that you can do an nslookup from the Windows 2008 machine to the machine you are doing the file copies and that the lookup doesn't take a long time (should happen as soon as you hit enter on the keyboard.  If you have to wait for even a second that's too long).

To xDUCKx: I did a "ipconfig /flushdns", and I checked nslookup - sucessfully. However, the issue still remains.

Resolution: server moved to same subnet as target host.
