# FW: [Windows] safe.directory: unreachable UNC entry stalls every command in a repo that fails the ownership check (~25 s) 1 messages from 2026-10-07 to 2026-10-07. Participants: Daniel Gullberg.

On Windows, a repository on an SMB share mapped to a drive letter (P: = file://192.168.56.101/TestDir, Samba on a VM; files are owned by a different SID than the current user) is used with a global config that lists several safe.directory entries. One entry points to a UNC path on a host that is currently not reachable:   git config --global --add safe.directory \       '//192.168.1.190/dummy-test/repo.git'   cd P:\   git status What did you expect to happen? An entry that cannot match the repository being opened should not slow down the command. "git status" should take about 2 s, as it does without the entry. What happened instead? The first "git status" takes about 29 s. Repeated runs shortly afterwards take about 1.8 s (Windows seems to cache the failed host lookup for a while). Removing the single unreachable entry from the global config brings the first run down to about 2.3 s. Timings (same repo, same session):   with unreachable safe.directory entry:  29.07 s, 1.93 s, 1.78 s   entry removed:                           2.27 s, 1.58 s GIT_TRACE2_PERF shows the time is spent before the worktree is set up, with no git work in between:   13:43:00.798  main  ancestry: git.exe, powershell.exe, ...   13:43:21.973  main  worktree://192.168.56.101/TestDir   (exit after 26.2 s total, of which about 5 s are git work) A plain filesystem probe of the dead host root from PowerShell (Test-Path '//192.168.1.190/dummy/') also takes about 25 s to fail, so the wait appears to be the Windows network connect timeout. My hypothesis, not verified in the source: the configured safe.directory values are normalized (resolved to a real path) when checked, which makes Windows contact the unreachable host. The ownership check is only done when the repository is not owned by the current user, which is always the case on this share. Comparing the entry against the repository path first, and only resolving entries that could match, would avoid contacting unrelated hosts. Impact: tools that run git often, such as TortoiseGit, pay the delay repeatedly (our Commit dialog took ~30 s to update). Stale entries for old or offline network locations are common, so this is easy to hit. What's different between what you expected and what happened? An unrelated, unreachable safe.directory entry makes git commands wait about 25 s. Anything else you want to add: Reproduced with Git for Windows 2.56.0.windows.2 and 2.46.1.windows.1.
