Troubleshooting context issues seems the right track. Consider:
-Start a_script.bat using %windir%\system32\runas.exe ([/noprofile |
/profile] [/env] [/netonly] Play with parameters to set and explore
context issues.
-Use the (well respected) psexec.exe from Sysinternals to confirm
remote execution using another means.
-Also from Sysinternals get and use ProcessExplorer, FileMon, TDIMon
and TCPMon
Other (possibly insulting to mention, please forgive) win batch
troubleshooting steps:
-REM out "@echo off" if any.
-Place a strategic "pause" in the batch to hold the command window open.
-Direct output from commands in the bat to a file "set >
c:\temp\bat_out1.txt" then look at the creator, owner, etc.
Prophylactic measures & things that effect the user context behavior:
-Check "launch folder windows in a seperate process" in
Explorer/Tools/Folder Options/View or you will not be able to run
explorer.exe as an alternate user.
-Uncheck "use simple file sharing" in same as above.
FWIW Getting runas to to fire cmd.exe, then a .bat can be tricky, I use
this to wrap runas, maybe it will help:
<rnas.bat>
:: Wrapper for runas.exe
:: If called with a parameter use it as target, otherwise start cmd.exe
:: !Note: /savecred is is convenient, but not very secure!
:: LAST EDIT EBS 2006-02-10
::@echo off
:: !Change _USER to domain and user to run as!
set _USER=domain\user
if %1! == ! (
%SYSTEMROOT%/system32/runas.exe /savecred /noprofile /user:%_USER%
"cmd.exe cd /D c:\\\_utils\"
goto END
) else (
%SYSTEMROOT%/system32/runas.exe /savecred /user:%_USER% "%~f1"
)
:END
::DIAGNOSTIC
pause
exit
</rnas.bat>
