Update OS to Windows Server 2019 Problem

[krgluski]

Hi,

After updating the OS to Windows Server 2019, the LanSweepr does not work.

I get the message in browser:

This is a marker file generated by the precompilation tool, and should not be deleted!

How can I resolve this problem?

Best regards.

Hello there!

The marker file error you're receiving indicates that the aspx files behind the page you're browsing to currently cannot be read. The website aspx files are compiled in DLL libraries that are part of your Lansweeper installation, and these are also cached in the ASP.NET cache. This issue is usually caused by an anti-virus interfering with these files or .NET corruption. We recommend clearing the ASP.NET cache, which may already resolve the issue.

• Stop your web server service. Your web server service is either World Wide Web Publishing Service (IIS) or IIS Express.
• Empty the folders listed below on your Lansweeper web server.

C:\WINDOWS\Microsoft.NET\Framework\v4.0.30319\Temporary ASP.NET Files
C:\WINDOWS\Microsoft.NET\Framework64\v4.0.30319\Temporary ASP.NET Files

• Start the web server service again.
• Test the web console.
• If the issue persists, reinstall the web console to restore system files:  https://www.lansweeper.com/knowledgebase/how-to-reinstall-your-lansweeper-website/

To prevent this issue in the future, we recommend the following:

• If your Lansweeper server has anti-virus installed, check its logs to see if there were any detections recently, specifically on the Lansweeper\Website folder or the .NET folders listed above. You may need to whitelist those folders.
• If no anti-virus is present or no detection occurred, you can try removing and reinstalling .NET on your Lansweeper server. Ensure both the web server and Lansweeper Server services are stopped during this process.
