[Samba] Solved: foo.bat works, but just 'foo' causes "not recognized as an internal ..."

[Tim Baverstock]

Hi folks. First time posting.

I've managed to puzzle the following out. I found a few other articles on 
the web that asked the same question, but my search terms didn't throw up an 
article with an answer, so I thought I'd write the following:

Where s: is a samba share that otherwise works for read/write:

----------------------------------------------
S:\misc\logs>foo.bat
'foo.bat' is not recognized as an internal or external command, operable 
program or batch file.
S:\misc\logs>echo @echo > foo.bat
S:\misc\logs>foo.bat
ECHO is on.
S:\misc\logs>foo
'foo' is not recognized as an internal or external command, operable program 
or batch file.
S:\misc\logs>set PATH=.;%PATH%
S:\misc\logs>set 
PATHEXT=.COM;.EXE;.BAT;.CMD;.VBS;.VBE;.JS;.JSE;.WSF;.WSH;.cmd;.bat;.exe;.Bat;.BaT;.BAt;.baT;.bAt;.bAT
S:\misc\logs>foo
'foo' is not recognized as an internal or external command, operable program 
or batch file.
----------------------------------------------

The file is created on the Unix side as 'foo.bat' - case preserved.

Both 'FileMon' by SysInternals and setting the Samba log level to 7 or so, 
showed Windows looking for FOO"* (rather than FOO.* which is more what I'd 
expect), but one of the lines in the logfile said 'wcard=FOO"*' which 
suggested it knew it was a wildcard.

It turns out that if I create FOO.BAT on Unix, running 'foo' on its own 
abruptly starts working.

Shame it took me over three hours to reach this point.

You'll notice the PATHEXT change - I had an inkling it was a case issue.

So... the problem's that the share is 'case sensitive = Yes' and cmd.exe 
helpfully uppercases executable command names typed in without extensions, 
but I'm sure you all knew that anyway.

Hopefully the various search engines will know about it too, henceforth.

Other reading suggests that for my application, the share should be set 
'case sensitive = No' 'preserve case = Yes'.

Cheers,

Tim
