Stripped it from the PATH. No change.

Funny you mention that. I either do a "SET PATH=C:\cygwin\bin;%PATH%" within
my cmd or include the cygwin path in the Windows Environment.

1. I call CMD.exe
2. If not already in the PATH, I add C:\cygwin\bin (as the first entry)
3. If asked for, I adjust CYGWIN ;)
4. I call any command (bash, ls, true, ...)
5. The command seems to start up
6. The command shuts down without any output
7. The %ERRORLEVEL% is 128

Whatever I do in step 2 and 3, it changes nothing.

That was what I did first, before I started digging. The bash prompt even
doesn't pop up. For your clear view: If I double-click the batch in Windows,
a cms.exe console windows pops up and goes away. So it looks like the
command really gets invoked. But invoking bash by double-clicking
cygwin.bat, is not any different from manually starting cmd.exe and calling
bash.

Also, adjusting CYGWIN within the batch makes no difference.

Since this wouldn't be the first time that I've been bugtracking for days
something that could be resolved by a restart, I restarted the (production!)
server yesterday. Also made no difference.

One more thing, I used FileMon to check for any files that are searched for
but not found. While executing e.g. ls, I found that SECUR32.DLL was sought
for in the cygwin/bin dir. I was not sure this was done by the cygwin
command, but I put it in that place anyway. Again, nothing changed. After
closing FileMon, I was unable to do any further investigation, as the prog
will not start again (Access Denied).

I really don't know what else I can check or try. I could restart the server
(at the end of the day), and do some further FileMon actions.

This is giving me a severe headache.
