Microsoft Windows NT 4.0 manual Troubleshooting User Profiles with the UserEnv.log File

nection, those credentials are also stored here. Note that this includes only the domain and user account name; the password is not included. When the user receives this profile and logs on, Windows NT attempts to reconnect the drive, but the alternate credentials are sent rather than those of the logged on user.. Note that if the UserName value contains a blank string, the credentials of the logged on user are sent (which is the desired behavior in this case).

To avoid inadequate credentials or wrong credentials being sent, use one of the following approaches:

∙Avoid having to supply alternate credentials when you create the connec- tions to network resources in the shared profile by granting the user creating the template profile sufficient permissions in advance.

∙Before modifying the profile to be a mandatory profile, run a REGINI script that removes the credentials from the UserName value. Do not delete the value, only the string data.

Troubleshooting User Profiles with the UserEnv.log File

The UserEnv.log is an invaluable tool for troubleshooting the process of load- ing and unloading User Profiles. Each step in the User Profile process is recorded in the log, including informational and error-related messages.

The checked version of the UserEnv.dll is the same dynamic link library (.dll) as the retail version, except that it contains debug flags that you can set and use with the kernel debugger. This file, which is included in both the Windows NT Device Driver Kit (DDK) and the Windows NT Software Devel- opment Kit (SDK), when used in conjunction with a registry entry, generates a log file that can be used in troubleshooting and debugging problems with roaming profiles and system policies on Windows NT 4.0 clients.

To enable logging:

1.Rename the file UserEnv.dll in the %systemroot%\SYSTEM32 directory to UserEnv.old or to a unique name of your choice.

2.Copy the checked version of UserEnv.dll to the %systemroot%\SYSTEM32 directory of the client machine that you want to debug. The checked version of the UserEnv file must match the version of the operating system and Service Pack installed on the client computer.

3.Start REGEDT32 and locate the following path:

HKEY_LOCAL_MACHINE \SOFTWARE

\Microsoft

\WindowsNT

\CurrentVersion

\Winlogon

4.Create a new value called UserEnvDebugLevel as a REG_DWORD type. Assign the hex value 10002.

5.Reboot the computer.

Logging information will be recorded in the root directory of the C drive as UserEnv.log. You can use Notepad to view the log file. A sample log is pro- vided next.

Windows NT 4.0 specifications

Microsoft Windows NT 4.0, released on July 29, 1996, marked a significant milestone in the evolution of Microsoft's operating systems. As the successor to Windows NT 3.51, this version brought a range of enhancements and features that appealed to both enterprise users and consumers.

One of the standout characteristics of Windows NT 4.0 was its introduction of the Windows 95 user interface, which significantly improved user experience and accessibility. This graphical interface made it easier for users to navigate the operating system, transitioning from the more complex interfaces of previous NT versions. The integration of familiar elements such as the Start menu and taskbar helped bridge the gap between professional and personal computing environments.

Windows NT 4.0 was built on a robust and secure architecture. It utilized the NT kernel, which provided improved multitasking and stability compared to its predecessors. This operating system was designed to handle multiple user sessions simultaneously, making it suitable for servers as well as workstations. The inherent stability of NT 4.0 made it a favorite in enterprise environments, particularly for critical applications and systems.

Another defining feature of NT 4.0 was its support for a wide range of hardware, making it versatile across various machine configurations. It included compatibility with numerous devices and peripherals, which facilitated its adoption in diverse settings.

In addition to user interface enhancements and hardware compatibility, Windows NT 4.0 introduced powerful networking capabilities. The operating system supported TCP/IP natively, alongside NetBEUI and IPX/SPX protocols. This meant that it could seamlessly integrate into existing network environments, providing essential services for file and printer sharing, domain management, and remote access through features like Remote Access Service (RAS).

Security was another key focus area for Windows NT 4.0. Built around security principles, it employed a discretionary access control system, allowing administrators to define user permissions and manage access to resources effectively. This was particularly appealing to businesses that needed to enforce strict security policies.

Windows NT 4.0 also included improved support for backup and recovery, through the inclusion of the NT Backup utility. The operating system allowed for the creation of scheduled backups and simplified data recovery processes, enhancing data integrity and reliability.

As NT 4.0 entered its later years, it laid the groundwork for future Windows operating systems, influencing the design of later versions, particularly Windows 2000. It combined user-friendly features with enterprise-level robustness, ultimately shaping expectations for modern operating systems across various industries.
