The User Profile Service failed the logon. User profile cannot be loaded

[nephilim]

For some reason, after doing a disk clean up and defrag etc, and running all updates on the computers over half term, we have major issues with the computers, they are refusing to log in stating "The User Profile Service failed the logon. User profile cannot be loaded" and then logs off.

I am at a loss as our system is crippled, and rolling back the machines to a previous point has not fixed this. Any and all help appreciated

Oh and we have tried what MS put on the website about the autofix thing.

Did you delete the user folders from c:\users ? If so then you'll need to tidy up the registry as well (HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\ProfileList
), otherwise windows thinks that's there's a locla profile that no longer exists.

Try user the local Users applet in the Control Panel to delete some test users from an affected system, then see if they can log on. I had this recently when I switched from roaming to mandatory profiles, deleting the roaming profiles from the PCs fixed it. Your mandatory/roaming profile may also be broken.

This happens to us randomly but a reboot usually fixes it, its not a wide spread problem though.
You got any firewalls?
Also DO NOT DELETE THE WHOLE PROFILE LIST KEY, only subkeys that are relevant

[nephilim]

mounters, what do I do with that registry key????

[nephilim]

also, is there a way to do this via GPO?

Remove the guids sub keys of any users whose local profile you deleted.

I don't think that you can do it through group policy.

No firewalls to cause this issue, which is annoying to say the least, I have deleted the Sub Keys, and profiles, but still having the issue. GAAAHHHHHHHH

Have you checked that the user profile service is starting up, maybe through remote management console.

Doing MSTSC to the server, the user profile services is on automatic. I might restart the server when the kids have left to see what that does to it.

You need to check it on the actual machine that you have a problem, also have you done the obvious of checking for malaware or virus infection. I would also try a SFC /scannow to see if any system files have been corrupted.

[nephilim]

well I can log in with SOME users but not others, which is annoying...so I would assume the services are running fine

Ok logon to the machine which you can and look at the event logs for any errors when you tried a user that failed. It should give you some errors to work on.

According to this a faulty application which is hanging in the registry/profile will stop it from loading.

If you get an event ID number for the users which are failing you can google it.

I have actually seen this in a different issue, we had a TS server (2008 R2) and when certain staff logged in they got the same error. The problem turned out to be an invalid profile path being set for the TS profile variable in their account (or GP I suppose)
