User cannot log into Mac on Windows network

Hello

We have a Tiger 10.4.10 Macintosh joined to a Windows domain.
Users can log into this machine with a user name and password just as they would on a Windows machine. Most users that is.

The main user of the Mac machine (she has a Windows domain account) now cannot log in. She types in her username and password which is accepted, then the desktop wallpaper appears and then the machine just hangs. The only way to recover is to switch off and back on again. The strange thing is other Windows domain users can still log in OK and I can log in with the local admin and Windows domain admin too.

I've tried renaming the Preferences folder of the user in question but it didn't do much. Now when you log in as her you just get the default wallpaper instead of her normal wallpaper and nothing else. It still hangs and the only way to recover it is to switch off and back on again.

Does anyone know how we can resolve this?
Info on the web about corrupt profiles/login problems seems to be very thin on the ground.

Thanks.

I'd try starting up the Disk Utility and doing a verify and repair (if needed) of the disk permissions and a verify of the main disk as well.

Barring anything found by the utility that fixes the issue, I'd log on as a local admin (although you may need root to do this) and rename her user folder.  Then have her log on again with her AD creds ... which should in essence create a new account folder set for her. See if everything works... if it does, she'll probably have rights to copy back important documents or other files that she needs.

Thanks jhyiesla

I'd already tried the renaming trick and it didn't work but the permissions did look a bit strange, I'll give the Disk Utility a go and let you know.

OS X works pretty well with AD, but personally I don't think it was until about 10.5.2-.4 that they really got it working right... and then broke part of it again in 10.5.5 and repaired most of it in 10.5.6... but that was mostly about SMB sharing.

I'm attaching a link that my be helpful from an AD overview perspective:

You might also try unbinding it from AD and then binding it again to see if that makes any difference.

Hello again.

I've performed a repair of permissions errors and fixed two naming errors it found when I checked the disk by booting using a install disk. I then renamed the users profile folder as suggested but no joy this user still gets a blank screen when they log in.

The disk utility seems to suggest that the next step is a re-install.
Would that be your next move or is there something else we can do?

Sorry I hadn't refreshed the screen before I submitted that last comment. I'll take a look at that link and give re-binding a go.

Thanks

If the rebinding doesn't work a reinstall would probably fix the issue, but always hate to do that if it's not necessary as it's a rather extreme option... even on a Mac. And if you choose to do an archive and install... you're probably just archiving the problem folders.

When you did the rename thing,  did you rename her user home folder right under the primary HD and then Users?   When she logs on she should then get a whole new user home folder... if there is corruption, it's probably somewhere in there.

A little puzzled but resting a bit easier now. It seems to have resolved itself.

When I did the folder rename the second time around and logged the user back in I could hear persistent disk activity. Previously I couldn't hear anything. I decided to leave the machine grinding; I came back to my desk and wrote my previous post and when I went back to the Mac the thing had logged in.
I logged out to make sure it wouldn't do the same thing again and this time it went straight in.

I'm assuming it was a combination of the disk errors and some kind of network issue (never got to do the re-binding).

Thanks very much for your help and the links. I'll keep them on hand for next time :)
