LabView over Ethernet

Hi everybody

I'm wondering about a minor anomaly. When i try to connect as client (Arduino) to a Server (LabView) i think the Arduino is connected but until the Connection is acepted and established it takes approx. 5s. Does anybody have some experiences with that?

I'm using an Arduino Mega 2560 with Ethernet Shield and a static IP.
On the PC Side i'm using a normal Win7 64-Bit OS with the LabView 8.2 Version.
