I've looked at the code, but I'm afraid I have no clue where this might come from. Without a debug level 10 log or a way to reproduce it I don't know how to fix this.

Sorry,

log level 10 plus tcpdump between PC and PDC

> Without a debug level 10 log or a way to reproduce...

Hi,

it looks like, it happens whenever WinXP machine is first turnup in the morning and user tries to login into the domain. I hope that attached loglevel 10 and ip tracedump between PC and PDC in "Comment #4" can help somehow.

Thanks, got it reproduced here. Expect a fix soon.

Two days of testing and i can say that this problem no longer exists. Volker, it was incredibly fast replay and fix. Thank you. Also i'm going to ask Debian to apply this patch into stable.

I have at least another problem, which does not occure on all computer (#6097 was also caused by minority of all PC). So during the weekend i would report another bug.

Thanks Volker for amazing speed!
