- Profiles don't load when users log on to a computer for the first time. Or, you log on to a computer where policy then deletes the cached profile after a date interval when you log off.
Note Logons that use mandatory user profiles or Virtual Desktop Infrastructure (VDI) may also be affected.
- Profiles don't load when users log on by using cached user profiles.
- Services don't start because of profile load failures. Affected services include but are not limited to the following:
- Local Service
- Network Service
Process Monitor may indicate that a CreateFile operation fails with an ACCESS DENIED result to the following path, depending on how file access is constrained:
See the failure details that are displayed in Process Monitor.
- Check whether the READ ONLY flag is set on the NTUSER.DAT or USERCLASS.DAT file for the profile that fails to load.
New user profiles are derived from C:\users\default\ during first-time account logons. If profiles fail to load with signatures that match those that are described in the "Symptoms" section, check whether the Read-Only bit is enabled on the NTUSER.DAT and USRCLASS.DAT files in the profile directory for the users or service accounts in question.
NTUSER.DAT in Windows Vista and later versions of Windows is located in C:\users\default\ntuser.dat. Earlier operating systems have other paths, such as C:\Documents and Settings\<username>\ntuser.dat.
The USRCLASS.DAT file is typically located along a path like C:\Documents and Settings\<user_name>\Local Settings\Application Data\Microsoft\Windows\UsrClass.dat or C:\Users\<user_name>\AppData\Local\Microsoft\Windows.
In Windows Explorer, right-click the NTUSER.DAT or USRCLASS file for the relevant default user or cached user profile. The Read-only check box should be cleared. It this check box is selected, it will cause profile load failures.
- Check the NTFS File System permissions setting on the NTUSER.DAT or USERCLASS.DAT file in the cached profile directory that fails to load.
Be aware that in the following screen shot, the test user, CONTOSO/testUser, has full control over NTUSER.DAT (not shown) and USRCLASS.DAT. Everyone is not listed in the ACL Editor group.
