TCP Header Checksums Displayed as Corrupted (using Network Monitor)

OK,so I was troubleshooting and odd issue with an FTP server and one of the things
that caught my attention while using Network Monitor (on a Windows 2000 server)
was that some(actually almost all) of the TCP checksums (originating from the server)
were found to be incorrect.


At first I thought I was having a networking problem,yet someone pointed out the fact
that since the calculation was being offloaded to the NIC Network Monitor may be
calculating the checksums incorrectly.
