Batch Scripts

I am trying to run/create a batch script for the users on my domain to install a program that will download and update flash and java. I have the .exe stored on the network share and currently have most of the script written. The part where i need help is to have to .exe run as one of our network administrators. Below is the code I have, where/how do I tell it to run as domain.local\networkadmin plus the account's password.

@echo off
cd C:\
mkdir CCFlash
copy \\toohey\CareCloud\CCFlash.exe C:\CCFlash
START C:\CCFlash\CCFlash.exe /silent S:\IT\CCFlashReports\reports.txt /repair


All help is appreciated.

EDIT: This script will run on XP Pro and Windows 7 Pro machines. 32 and 64 bit.

Take a look at the runas command, it should give you what you need

RUNAS USAGE:

RUNAS [ [/noprofile | /profile] [/env] [/savecred | /netonly] ]
/user:<UserName> program

RUNAS [ [/noprofile | /profile] [/env] [/savecred] ]
/smartcard [/user:<UserName>] program

RUNAS /trustlevel:<TrustLevel> program

/noprofile specifies that the user's profile should not be loaded.
This causes the application to load more quickly, but
can cause some applications to malfunction.
/profile specifies that the user's profile should be loaded.
This is the default.
/env to use current environment instead of user's.
/netonly use if the credentials specified are for remote
access only.
/savecred to use credentials previously saved by the user.
This option is not available on Windows 7 Home or Windows 7
Starter Editions
and will be ignored.
/smartcard use if the credentials are to be supplied from a
smartcard.
/user <UserName> should be in form USER@DOMAIN or DOMAIN\USER
/showtrustlevels displays the trust levels that can be used as arguments
to /trustlevel.
/trustlevel <Level> should be one of levels enumerated
in /showtrustlevels.
program command line for EXE. See below for examples

Examples:
> runas /noprofile /user:mymachine\administrator cmd
> runas /profile /env /user:mydomain\admin "mmc %windir%\system32\dsa.msc"
> runas /env /user:user@domain.microsoft.com "notepad \"my file.txt\""

NOTE: Enter user's password only when prompted.
NOTE: /profile is not compatible with /netonly.
NOTE: /savecred is not compatible with /smartcard.

Sorry for confusion - the runas is a replacement for the regular start command

you should also be able to add the parameters from you start instruction in you original script, but you may need to "play" with the quotes to get it to accept them
