Problem:
You can use runas
command to run a command with specific user privilege.
(Note: You have to type password into command prompt):
C:\>runas /user:domain\username cmd
Enter the password for domain\username:
Attempting to start cmd as user "domain\username" ...
But, you will get error with a command with arguments:
C:\>runas /user:domain\username net start WebClient
RUNAS USAGE:
RUNAS [ [/noprofile | /profile] [/env] [/savecred | /netonly] ]
/user:<UserName> program
You can also use Start-Process -Verb runas
with the same aim without typing password (UAC dialog will pop up for privileges):
PS > Start-Process -Verb runas cmd
But you will get an error when you want pass arguments to the command:
PS > Start-Process -Verb runas net start WebClient
Start-Process : A positional parameter cannot be found that accepts argument 'WebClient'.
At line:1 char:1
+ Start-Process <<<< -Verb runas net start WebClient
+ CategoryInfo : InvalidArgument: (:) [Start-Process]、ParameterBindingException
+ FullyQualifiedErrorId : PositionalParameterNotFound,Microsoft.PowerShell.Commands.StartProcessCommand
Or you will get another error when you quote the command and arguments:
PS > Start-Process -Verb runas "net start WebClient"
Start-Process : This command cannot be executed due to the error: The system ca
nnot find the file specified.
At line:1 char:14
+ Start-Process <<<< -Verb runas "net start WebClient"
+ CategoryInfo : InvalidOperation: (:) [Start-Process]、InvalidOperationException
+ FullyQualifiedErrorId : InvalidOperationException,Microsoft.PowerShell.Commands.StartProcessCommand
Solution:
You should quote the command and arguments in runas
command:
C:\>runas /user:domain\username "net start WebClient"
Enter the password for domain\username:
Attempting to start net start WebClient as user "domain\username" ...
You should use -ArgumentList
option to pass argument in Start-Process
cmdlet:
Start-Process -Verb runas -ArgumentList "stop WebClient" net
