Checksum incorrect

Subject:Checksum incorrect

Hi all,
using Indy and ICS I send TCP messages.
This seems to work but if I "sniff" the lan, using ethereal I see error messages like:

"checksum: 0xa441 [Incorrect, should be 0xeac9]"

I can't control the checksum with Indy or ICS, I only send command.

Why happens?
Is a problem?
What can I do?

Many thanks.
Giorgio.
