When running the runas.exe command, you cannot specify the password on the command line. This small application fixes that.
Example of starting Microsoft SQL Server Management Studio
RunAsX.exe /dl:MyDomain\MyUser /p:Password1 /f:"C:\Program Files\ManagementStudio\Ssms.exe"
Command line swithes:
/dl (or /DomainLogin) - domain login, e.g CompanyDomain\username
/p (or /Password) - password
/f:{file to execute) - file to execute
/a:{arguments to pass to file} - not working at the moment
