Corrupt User Environment new user issues

Your profile settings (desktop icons, application settings, and so on) are reset to the default. If you look in the %SystemRoot%\Profiles folder, you should see your profile directory has been renamed to %SystemRoot%\Profiles\Username.bak, and a new default profile has been stored in %SystemRoot%\Profiles\Username. This is done to allow a user to log on successfully if the profile has been corrupted or does not load for some other reason.

If the registry size limit has been exceeded, a system pop-up message indicating this will be presented to the user during the first logon attempt when this occurs. The following message will be displayed:


System Process - Low on Registry Quota: Your system is running low on
registry quota. Start the System option in the Control Panel and choose
the Virtual Memory button to increase the registry quota.

During subsequent logon attempts, profile load errors will occur and the following application events will be logged:

   Event ID 1000 userenv RegLoadKey failed with error 1009 for
   C:\WINNT\Profiles\username\ntuser.dat

   Event ID 1000 userenv The operating system was unable to load the
   locally stored profile.  A new local profile will be created. (1009)
                        

Although the user profile registry keys may fail to load for a number of reasons, one status code is always returned indicating that the profile is corrupted. The Registry Size Limit (RSL) may have been exceeded. The RSL is a user-defined quota that places a maximum upper limit on how large the registry can grow. When this limit is approached, a message stating this in the Application Popup dialog box will be presented to the user. Because the loading of a user profile (stored in Ntuser.dat) consumes Registry Quota, this may contribute to the exhaustion of this resource.

RESOLUTION:
A User Profile does not load if the RSL has been exceeded. This is by design. To work around this problem, the RSL can be increased to avoid the restriction. To do this, follow these steps: 1. In Control Panel, double-click System.  
2. On the Performance tab, click Change in the Virtual Memory section.  
3. In the Virtual Memory dialog box, in the Registry Size section, the current registry size and the maximum registry size are displayed. Modify the current RSL in this section.  
Microsoft recommends increasing the RSL only enough to accommodate the current Registry and a small amount of growth. For additional information, please see the following article in the Microsoft Knowledge Base:

System Is Running Low on Registry Quota
Windows 2000
Windows 2000 includes a UserEnv enhancement so that the user profile is not deleted if or when the profile is not corrupt. A pop-up message is provided indicating insufficient resources. The user is then logged off if the user does not have local administrative privileges or the user is logged on when administrative privileges are identified. The administrator can then increase the registry size limit and log on again. The user profile used prior to the problem is still being saved on the local computer unless it has just been copied.

Note A restart is required after RSL has been increased either by using Control Panel or by editing the registry, because this change does not happen dynamically and you may still experience the following event:
Event Type: Error
Event Source: Userenv
Event Category: None
Event ID: 1000
Date: Date
Time: Time
User: NT AUTHORITY\SYSTEM
Computer: ComputerName
Description: RegLoadKey failed.
Return value: Insufficient system resources exist to complete the requested service for C:\Documents and Settings\ntuser.dat.
