Ip Header Checksum Error

We have created a socket program (using winsock control) in Visual Basic under windows 2000 platform . And using this application we are transfering data from a PC to our custom Board through 1000 base T Fibre Optic Ethernet card...

While transferiing data from Pc to the Board .. we are getting IP Header Checksum Error

Ethernet II: Header checksum 0X0000: [incorrect,should be 0Xf2a0]

What is the cause of this error.. does any changes need to be made in the VB application to clear this error.. or any compatiblity problem

can any one help me to sort out this problem?

Which component in this configuration was made by Cisco?

What is reporting this problem? If you are sniffing traffic on the same system that is producing the traffic, then you might be encountering a common issue: if the IP driver has been set to offload checksum calculations to the ethernet card, then packets that gets sniffed before being submitted to the cards will not have had their checksum updated yet.
