I have suddenly gotten quite a special problem. I am thinking the error might have to lay with a update to Windows Vista.
I base this on the fact that from I was running NIS09 in beta until about a month ago I had no problems with NIS09 and booting and logging onto the domain server.
I have tried reinstalling several times, doing diffrent aproaches. And the problem first comes up when I add the computer to the domain. Before that I have no problems. Reinstalling NIS09 after boot is also causing no problems, the only issue is that I will have to remove NIS09 before reboot ore using safe mode before I will be able to get a successfull boot into windows. If I forget it will hang for a period of 10-15 min before showing the login screen, and after entering login information it will again hang but it will not get any further.
System in question is running Windows Vista x64, all updates for Windows installed and same goes for NIS09 when tested with rebooting.
