• I was not able to find an open or closed issue matching what I'm seeing

This issue is very similar to 2753 and 1345 but not identical.

Setup

• Which version of Git for Windows are you using? Is it 32-bit or 64-bit?

$ git --version --build-options

git version 2.41.0.windows.3
cpu: x86_64
built from commit: 4a1821dfb0c2160a4fcc85d2845f095c54339578
sizeof-long: 4
sizeof-size_t: 8
shell-path: /bin/sh
feature: fsmonitor--daemon

• Which version of Windows are you running? Vista, 7, 8, 10? Is it 32-bit or 64-bit?

$ cmd.exe /c ver

Windows Server 2019 Standard

Microsoft Windows [Version 10.0.17763.4737]

• What options did you set as part of the installation? Or did you choose the
  defaults?

> type "C:\Program Files\Git\etc\install-options.txt"

Editor Option: VIM
Custom Editor Path:
Default Branch Option:
Path Option: Cmd
SSH Option: OpenSSH
Tortoise Option: false
CURL Option: OpenSSL
CRLF Option: CRLFAlways
Bash Terminal Option: MinTTY
Git Pull Behavior Option: Merge
Use Credential Manager: Enabled
Performance Tweaks FSCache: Enabled

• Any other interesting things about your environment that might be related
  to the issue you're seeing?

File shares are fronted with Windows Distributed File System, making them accessible in a single namespace.

Details

• Which terminal/shell are you running Git from? e.g Bash/CMD/PowerShell/other

Issue occurs when running from Git Bash, CMD and PowerShell. Issue occurs when using navigating to share via UNC path or by mapping a network drive and using drive letter.

• What commands did you run to trigger this issue? If you can provide a
  Minimal, Complete, and Verifiable example
  this will help us understand the issue.

cd \\domain.contoso.com\dfs\share
git clone https://github.com/git-for-windows/git.git git-for-windows

• What did you expect to occur after running these commands?

I expected the clone to succeed to the DFS share.

• What actually happened instead?

Downgrading to Git for Windows 2.18.0 (per the issues I referenced at the beginning) seems to resolve the issue but is not feasible for our environment.

This ticket looks like it would benefit from #4528, i.e. upgrading to v2.42.0(2) and setting windows.appendAtomically to false.

Thanks for the suggestion, but no difference in behavior so far (now testing on a local Windows 10 PC):
