fatal: unable to access 'H:\/.config/git/config': Invalid argument [Git on Windows 7]

I experienced a similar issue when not connected to my work network via VPN. Running the following from a command window worked for me:

net use H: /delete

This command actually deleted the H drive. If you actually use the mapped drive that is causing the issue, then this way could cause you other problems that would only be solved by remapping the drive (net use H:, followed by the mapped drive path). As a note, I did delete the HOME% variables (using "set HOME=" from the command line), but it did work until the command above was run.

A lot of solutions were presented. Conclusion: The problem is a remote HOMEPATH and HOMEDRIVE environmental variable and appears when you are not connected to your network.

IMHO the solution with no side-effects (when your HOME variable is not set) is setting your HOME environmental variable of your profile to an existing local path.

First check if HOME is set or not. Open cmd.exe (Command prompt) and type

set HOME

If you do not get a result, just for HOMEPATH and HOMEDRIVE, than HOME is NOT set. Go to control panel:

Press WIN-R and then type control. Go to users profiles and you find a link on the left sidebar to change the environmental variable of your profile. The rest should be self-explanatory. Add variable HOME with path e.g. c:\users\myprofile.

With this attempt you could let HOMEPATH and HOMEDRIVE untouched and get no side-effects when reconnected to your network.

Worked for me.

IMPORTANT: But you lose your git settings. So you have to copy at least .gitconfig from your remote network home drive to your new local HOME directory before you disconnect from your network.

net delete is not a must.

First check HOME setting, then change HOME and HOMEDRIVE to a existing dir.

c:\git\selenium-automation>set HOMEHOME=U:\HOMEDRIVE=U:HOMEPATH=\HOMESHARE=\\XX

then change HOME and HOMEDRIVE by

set HOME=c:\tmpset HOMEDRIVE=C:

c:\git\selenium-automation>set HOME

HOME=c:\tmpHOMEDRIVE=c:HOMEPATH=\HOMESHARE=\\XX
