Windows NT Setup for Windows NT 3.51 Fails When Deleting User Profiles (175544)
The information in this article applies to:
- Microsoft Windows NT Workstation 3.51
- Microsoft Windows NT Server 3.51
This article was previously published under Q175544 SYMPTOMS
Selecting Options | Delete user profiles..., from Windows NT Setup for
Windows NT 3.51 results in the following error message:
No user profiles were found on this machine.
-Or-
The following Dr. Watson error message is displayed:
An application error has occurred and an application
error log is being generated.
Setup.exe
Exception: access violation (0xc0000005), Address: 0x77f52edb
CAUSE
The stack trace shows the access violation occurs in GetUserAccounts.
The GetUserAccounts function enumerates the user profile summary
information from the following registry key:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT
\CurrentVersion\ProfileList
NOTE: The above registry key is one path; it has been wrapped for
readability.
The receive buffer for the enumeration is set to a fixed length. For the
case of approximately nine or more user profiles, the fixed buffer gets
overwritten during enumeration, which results in the Dr. Watson access
violation.
WORKAROUND
To work around this problem, delete the user profile(s) manually using the
following procedure:
WARNING: Using Registry Editor incorrectly can cause serious problems that
may require you to reinstall your operating system. Microsoft cannot
guarantee that problems resulting from the incorrect use of Registry Editor
can be solved. Use Registry Editor at your own risk.
For information about how to edit the registry, view the "Changing Keys And
Values" Help topic in Registry Editor (Regedit.exe) or the "Add and Delete
Information in the Registry" and "Edit Registry Data" Help topics in
Regedt32.exe. Note that you should back up the registry before you edit it.
- Start Registry Editor (Regedt32.exe), and select the following subkey:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\WindowsNT
\CurrentVersion\ProfileList
NOTE: The above registry key is one path; it has been wrapped for
readability.
- Click Save Key from the Registry menu to create a backup copy of this
parent key.
- Within this key, select the subkey that represents the user profile that
you wish to delete.
You can typically determine the user name for the profile subkey by
referring to the ProfileImagePath value of that subkey. Make a note of
that profile's ProfileImagePath value, because this information is used
in a later step to delete the actual user profile.
- Delete the user profile subkey.
- From a command prompt, start File Manager. Go to the path referenced in
the ProfileImagePath value of the user profile subkey just deleted, and
delete the file referenced at the end of the ProfileImagePath value.
RESOLUTION
Obtain the updated Setupdll.dll from Microsoft Product Support Services.
