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
[quote]
FF 51 0C 00 00 02 00 00
[/quote]

Now the result code (DWORD) in the packet is
[quote]
00 02 00 00
[/quote]

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
