Undocumented SID_AUTH_CHECK result...

[Sorc.Polgara]

I am occasionally getting IP Banned from the server temporarily after sending 0x51.  The am positive that the packet is correctly sent and assembled.  The result I am recieving is not documented on BnetDocs, however there is a comment concerning it on there but not quite answered.

Here is the recieved packet

FF 51 0C 00 00 02 00 00

Now the result code (DWORD) in the packet is

00 02 00 00

Does anyone have any information on what this result means? why I am getting IP banned temporarily?

According to my bot:

case 0x200:
    throw new InvalidCDKey("Invalid cdkey");


Edit: BNetDocs says the same thing
