Ok, this has happened to two of the users at my work place and I do not know why it is happening. The user would log on to Windows and XP would create a new profile folder with .000 added to it. The user has not done anything different and is using the same password. Only way I can fix the problem is to delete the new 'user.000' folder and rename the original folder from 'user' to 'user.000'. I would then have to re-direct all Outlook PST files that was from the user folder to the user.000 folder. I've seen this happen on NT machines before and in the past, all I did was delete the new profile. We ran spyware and anti-virus and the computer is very clean. Does anyone know why this might happen and is there a way of fixing it? I assume I can go into the Registry somewhere to fix. Thanks in advance.
