IIS: Error 503 on port 80

On an IIS server, with a simple static web page, I constantly got: HTTP Error 503. The service is unavailable I did not get any entry in the IIS logs and when stopping the respective app pool, I got the same message.

And - bingo - , on port 81, the web site worked. After digging for a while, I found that port 80 had an "ACL reservation". Read more [...]

Windows: How to check and set Symlink Permissions

If you have clicked on a Symbolic Link (SymLink) in Windows and got the following error message:

"The symbolic link cannot be followed, because its type is disabled"

fsutil behavior set SymlinkEvaluation R2R:1 R2L:1

Windows: How to create a Symbolic Link

With the onboard tools of Windows, you can only create symbolic links with the command line (unless you download some third-party GUI tool). The syntax is as follows:

mklink /D "c:\inetpub\External" "\\server\share"

This will create a folder c:\inetpub\External and it will point to a share on a server. You can delete c:\inetpub\External via normal File Explorer, it will only delete the Symbolic Link, not the destination share.

After installing Windows Server 2019 Standard, I tried to activate it with a MAK key from the Microsoft Volume Licensing Portal.

The key part is "installation of a Windows Server role or feature". So this was not talking about a normal pending reboot Read more [...]

Windows: "The request was aborted: Could not create SSL/TLS secure channel"

I recently had a problem on an Office Web App Server (Windows Server 2012 R2). To show a document in Web View, it had to fetch it from another server via HTTPS. This failed. The ULS log showed: "The request was aborted: Could not create SSL/TLS secure channel" When I used Internet Explorer from the Office Web App Server, I could connect to the other server via HTTPS no problem. So the certificate was not the problem, it was trusted on the Office Web App Server. After hours of searching, I Read more [...]
