This is a short post, and mainly for my own reference in the future. I run a MacBook Air at work and have Windows 7 running on a VirtualBox VM. It’s a long story as to why, but my Windows VM is not joined on our work domain (Active Directory). Most of the time this isn’t a big deal but occasionally there are times I really do need to run a program in the context of my Active Directory domain user. A good example is SQL Server Management Studio, because to connect to servers with “Windows Authentication” it assumes you are already running SSMS in the context of the Windows user you will be connecting with. Since my box isn’t even connected to the domain, this is a problem. To get around this, I changed my SSMS shortcut to use the following command. This command opens a command prompt, asks me to enter my password, and then opens a program in the context of the user I specify.
C:\Windows\System32\runas.exe /netonly /user:MYDOMAIN\username "C:\Program Files (x86)\yada\yada.exe"
