i want to run a batchfile with a runas command in it. Is it possible to link the password in Batch file? For example: runas /profile /user\domain PASSWORD thanks in advance for your answers
Answer
An Alternate Solution
It looks as though runas does not allow what you want (without severely compromising security... see below). However, there is a third-party utility called PsExec which does allow this. From the Sysinternals PsExec page:
Usage: psexec [\\computer[,computer2[,...] | @file\]][-u user [-p psswd][-n s] [-r servicename][-h][-l][-s|-e][-x][-i [session]] [-c executable [-f|-v]][-w directory][-d] [-<priority>][-a n,n,...] cmd [arguments]
(Note: the idea to use PsExec came from Lauren7060's answer to this question on Spiceworks).
So, something like:
psexec -u MYUSER -p MYPASSWORD MYBATCH.BAT
should do what you want.
What Doesn't Work
As you found, runas normally prompts the user to enter the password. Interestingly, you can either pipe data into runas:
echo password | runas ...
or redirect input from a file:
runas ... < PASSWORD.TXT
and runas will not prompt for a password. However, I could not get runas to accept the password as valid, however I formatted the data. In the latter case (redirecting from a file), I tried both with and without a line-ending, but neither worked. My guess is that the pipe/redirect is enough to stop runas prompting for a password, but that it doesn't really read anything from stdin. This is partially supported by this article on the Tech Torials website that describes a method where you can use runas without it prompting for a password, but only if you set the account's password to an empty string.
