I know there are still some issues with update to windows 2004. Our user have problem with this update. It is always stuck in 49 %. We are using WSUS.
I search problem and there is info, some PC have problem, because this update is compactible with some drivers.
So Im putting sample of drivers here, which could cause problem. See linkt bellow (link to 2 files with report). This should be reported to developers but I dont know If this is correct forum.
If not, please let me know where I should put this question.
