Darren, I have noticed in my testing that this error appears on the first logon, if a user profile does not exist. The user can then subsequently logon without this error. I am testing to see if this error appears when a user profile already exists. I have been able to fix the issue by deleting the history and then loading the hive of the user profile experiencing the problem. We image our desktop computers, however there are many different variations in the images. We are working on standardizing, but you know how that goes. It may be that there is something built into our image that is contributing to this problem. I find it interesting however, that it appears to be occurring only on first logon. All desktops are XP SP1. Do you think it could have something to do with how GPO is applied, asynchronous\synchronous? Regards, Cynthia Berridge IT Dept.

The latter is going to be tough to deal with for 5,000 users because they have to be logged on in order to delete those history subkeys, but by default, normal non-administrative users don't have access to those keys. I really wonder if this is the true problem and if so, why its happening on such a large scale. Have you been able to fix the problem by deleting history on a single computer and user yet?

Event ID 1047 from Userenv is logged in the event logs. I have followed instructions according to Microsoft Article 319006 and deleted the History sub keys from the registry as well as deleting any existing profiles from the desktop. The error continues to appear. Does anyone know how to detect and repair this problem on a large scale? I have about 5,000 computers to work with. Thank you, Regards, Cynthia Berridge
