DnsServer starts but immediately fails - Event ID 1026

[mwherman2000]

When I try to start the DnsServer from the DNS Server App (Service > Start), I get the service started message but the service immediately fails (stops). DNS Server is being installed with compiled DnsServerSetup supplied with the project.

Application: DnsService.exe

.NET Version: 7.0.5

This is a fresh installation of DnsServer 11.1.1 on a Windows 11 Pro laptop. DnsServer has never been installed on the machine previously.

start.bat works properly

Thanks for the post. It seems that you have missed pulling the latest code for TechnitiumLibrary repo. Pull the code for it and then follow the steps to generate the windows setup.

[mwherman2000]

We pulled it around noon today and followed Step 3 in these instructions: https://github.com/TechnitiumSoftware/DnsServer/blob/master/build.md#for-windows

[ShreyasZare]

Ok then it seems that for some reason, an older version of the DLL file is being installed. Try to compile both the solutions again in release mode and publish the system tray app and the windows service projects again.

No luck

Exception Info: System.IO.FileNotFoundException: Could not load file or assembly 'TechnitiumLibrary.Net, Version=8.2.1.0, Culture=neutral, PublicKeyToken=null'. The system cannot find the file specified.

Is this a problem with TechnitiumLibrary.Net missing or being the wrong version? ...or if TechnitiumLibrary.Net has a dependency on another assembly, can this also be part of the problem?

I need to leave this for this evening but we still need to figure this out.

What is the correct/most recent version of TechnitiumLibrary.Net?

The error message comes same for both conditions. Check if the file exists in the installation folder. If it exists then its the wrong version issue.

The recent version is 8.2.1 which the DNS server process is expecting.

[mwherman2000]

This looks all correct...

[ShreyasZare]

I am not exactly sure why its not working. However, there are some extra Technitium Library DLLs in the screenshot you posted that should not exists in the installation folder. You should have only the following DLLs files shown below:

Have you copied all the DLL files from the library project's bin folder here?

Are you using the exact output files generated when you publish both the DnsServerSystemTrayApp and DnsServerWindowsService projects from the DnsServer\DnsServerWindowsSetup\publish folder?

[mwherman2000]

I've fixed the problem and it may have been my "user error" all along. My apologies for the firedrill.

We're about to add about a dozen custom resource records for our Web 7.0 project and in the past versions (from years ago), we'd link the TechnitiumLibrary projects into the DNSServer.sln solution so that we could compile and edit both sets of projects from the DNSServer solution. I think this messed things up. So we're back to keeping the 2 solutions completely separate.

My apologies.

Good to know you got it working.
