question about nltest result


Recommended Posts

O:\>nltest /sc_query:acro.ca

Flags: 30 HAS_IP HAS_TIMESERV

Trusted DC Name \\acrodhcp.acro.ca

Trusted DC Connection Status Status = 0 0x0 NERR_Success

The command completed successfully

O:\>nltest /server:acrofiles2 /sc_query:acro.ca

I_NetLogonControl failed: Status = 1355 0x54b ERROR_NO_SUCH_DOMAIN

O:\>nltest /server:acrodhcp /sc_query:acro.ca

Flags: 30 HAS_IP HAS_TIMESERV

Trusted DC Name \\acrofiles2.acro.ca

Trusted DC Connection Status Status = 0 0x0 NERR_Success

The command completed successfully

acrofiles2 is a dc which is also the operations master.

acrodhcp is a dc as well.

this is a mixed mode win2k domain.

my question is, which ever dc authenticates me is the one i establish a secure channel with correct? then that is why acrofiles2 failed, because acrodhcp authenticated me?

then how come :

O:\>nltest /server:acrodhcp /sc_query:acro.ca

Flags: 30 HAS_IP HAS_TIMESERV

Trusted DC Name \\acrofiles2.acro.ca

Trusted DC Connection Status Status = 0 0x0 NERR_Success

The command completed successfully

this command produced a trusted dc name of \\acrofiles2.acro.ca and not acrodhcp.acro.ca?

sorry i havent been using nltest before, but i'm just curious at the results.

thanks for the reply,

i just have one more peculiar question.

out of curiosity i ran this command on my print server (no active directory installed on it)

O:\>nltest /server:acroprint /sc_query:acro.ca

Flags: 30 HAS_IP HAS_TIMESERV

Trusted DC Name \\ACRODHCP

Trusted DC Connection Status Status = 0 0x0 NERR_Success

The command completed successfully

does anyone know why when i run the same command on acrofiles2 (my operations master dc) i get this:

O:\>nltest /server:acrofiles2 /sc_query:acro.ca

I_NetLogonControl failed: Status = 1355 0x54b ERROR_NO_SUCH_DOMAIN

?

i'm just curious as to why every server has produced some sort of positive result and this one gives an error? and its towards my first dc i put up in my domain.

If you receive the following error, ERROR_NO_SUCH_DOMAIN while using the Nltest tool to query the secure channel, this is usually indicative of the inability to find a domain controller for that domain. Run nltest /dsgetdc: <DomainName>: to verify whether you can locate a domain controller. If you are unable to find a domain controller examine DNS registrations and network connectivity.

The Netdiag tool helps to isolate networking and connectivity problems by performing a series of tests. If you are unable to resolve a name, you might be experiencing DNS registration or consistency problems. To confirm this, answer the following questions:

When you run Netdiag, do you receive any DNS error messages?

To verify the DNS registration for your domain, the best tool to use is netdiag /debug, which must be run on all domain controllers.

To refresh all DHCP leases and re-register DNS names for computers, use the ipconfig /registerdns command. To refresh and re-register DNS names for domain controllers, stop and start the Net Logon service. By default, the Net Logon service automatically re-registers DNS names every hour.

Using DNSCMD to Check Consistency

Dnscmd.exe is a command-line tool that you can use to view the properties of DNS servers, zones, and resource records. To be able to check your DNS server configuration, use the Dnscmd tool or the DNS Manager console to obtain information about the DNS server and obtain statistics about its performance.

Dnscmd is also used to manually modify DNS server properties, to create and delete zones and resource records, and to force replication events between DNS server physical memory and DNS databases and data files.

O:\>nltest /dsgetdc:acro.ca

DC: \\acrofiles2.acro.ca

Address: \\192.168.4.44

- Opening \Device\NwlnkIpx failed (found on both dc's to have the same output)

- Trust relationship test. . . . . . : Skipped (this output frm acrofiles2 my first dc)

- Trust relationship test. . . . . . : Passed (this output from acrodhcp my 2nd dc)

Test to ensure DomainSid of domain 'ACRO' is correct.

Secure channel for domain 'ACRO' is to '\\acrofiles2.acro.ca'.

Secure channel for domain 'ACRO' was successfully set to PDC emulator '\\acrofiles2.acro.ca'.

i have the following services disabled on my operations master dc (acrofiles2)

With BleachBit you can free cache, delete cookies, clear Internet history, shred temporary files, delete logs, and discard junk you didn't know was there. Designed for Linux and Windows systems, it wipes clean thousands of applications including Firefox, Microsoft Edge, Google Chrome, Opera, Safari, and more. Beyond simply deleting files, BleachBit includes advanced features such as shredding files to prevent recovery, wiping free disk space to hide traces of files deleted by other applications, and vacuuming Firefox to make it faster. Better than free, BleachBit is open source. BleachBit has many useful features: Delete your private files so completely that "even God can't read them" according to South Carolina Representative Trey Gowdy. Simple operation: read the descriptions, check the boxes you want, click preview, and click delete.

This maintenance-focused release includes bug fixes, updated translations, and a range of safe enhancements. This release fixes a Windows security issue that could allow arbitrary file deletion during privileged cleaning (reported by Zeze with TeamT5). It also adds new cleaners (including a DNS cache cleaner, Claude Code, and Visual Studio Code forks), support for multiple Chrome and Edge profiles, new deep scan options for developer directories like node_modules and venv, and safer, faster file shredding. All Platforms Added cleaners for Claude Code, DNS cache, and many Visual Studio Code forks. Added support for multiple Chrome and Edge profiles. Chrome can now clean downloaded AI models. Deep Scan can optionally remove venv, __pycache__, node_modules, and .angular directories. Deep Scan is faster by skipping directories on the keep list. File shredding is safer, faster, and leaves fewer recoverable traces. Improved handling of cookies, symlinks, Unicode filenames, external processes, and configuration files. Improved Expert Mode warnings and long warning dialogs. Fixed crashes related to cleaner detection, invalid Unicode, and malformed cleaner data. Clipboard is now cleared automatically after shredding files via paste operations. Linux Added AppImage support. Added cleaners for Visual Studio Code, Codeium, Librewolf (.deb), Transmission (Flatpak), and Profanity. Improved Linux trash detection, including Snap-installed applications and mounted drives. Fixed Wayland root CLI issues and several Snap-related problems. Improved package dependencies, AppStream metadata, and desktop file handling. Fixed startup crashes when Python Requests is unavailable. Windows Fixed a security vulnerability that could allow arbitrary file deletion when cleaning with elevated privileges. Added %WindowsSystem% variable support. Improved clipboard clearing using native Windows APIs. Improved installer experience on unsupported Windows versions. Reduced installer size and improved application robustness. Fixed Unicode handling, filename anonymization, Git revision reporting, and splash screen stability.

    • DriversCloud 12.1.6 by Razvan Serea With DriversCloud (formerly My-Config.com), you can explore your computer easily, safely and free. The application quickly scans your PC and identifies the hardware and software components. DriversCloud then establishes a list of the different drivers compatible with your OS and hardware. Download the drivers needed for the proper functioning of your computer. To detect your drivers, DriversCloud also displays a detailed summary of your hardware and software configuration, analyzes your BSOD, monitors in real-time your PC voltages and temperatures and lets you share your configuration online. Once the hardware components have been detected, you will be able to obtain with just a few clicks the latest drivers corresponding to the identified hardware. You can record your configuration on the site for free, and can get the corresponding URL to post the configuration to technical forums, e-mail and social networks. You can also download the detection result (the configuration) as a PDF file. To protect the user's privacy and data confidentiality, a 4-level confidentiality system was created that filters the XML marks and gives control to the user. The default level can be modified in the preferences. Using the maximum level will prevent the user from publishing his configuration and generating a corresponding PDF file. In non-connected mode, each XML configuration is stored on the server for one day (for practical reasons). However, you are given the opportunity to manually delete it. Created in 2004, and continually improved, My-Config.com has established itself on the web as a free service to PC users running Windows and Linux operating systems. The service is designed to work with the most common Internet browsers (Edge, Firefox, Chrome, Safari).
