back in september 2008 the blizz servers went down for some hours and when they were up again my namebot couldnt connect anymore. each time i try to connect it i get 5 min realm down. i guess this is because they updated something serverside?
anyone knows what blizz did change back there?

probably would help to explain what your bot did, so we could figure out what might have changed...... probably just a verbyte.

well its a diablo 2 namebot which creates charnames ^^. its still using the bnetauth.dll. and no the verbyte is correct. it was working fine till blizzard did some maintenance (no new patch or anything)

What part in the login sequence does the bot fail? It would be helpful to know this information, as you can pinpoint which part battle.net changed.

hm.
[12:48:44,770] Connecting..
[12:48:45,270] Connected
[12:48:45,330] You should never get this error.
[12:48:45,330] Disconnected.

after that im getting 5 min RD. is there any tool which shows the packets im sending? so i could see after what packet im getting RD.

also are there any other  bots which are using bnetauth.dll and still work?

In your packet buffer, place an AddChat after each packet is about to be sent.

Ex:

[code]
Private Sub SendPacker(ByVal PacketID As Byte)
  AddChat vbYellow, "Send packet 0x" & Hex(ID)
...
End Sub
[/code]

Something like that.

Can i see your packet log and codes ?
