Q. I want to manage a remote DNS server that is in an untrusted domain so need to send credentials. How can I do this?
A. The easiest way to do this and it applies to any remote management is to create a new mmc.exe instance as the remote user then add the DNS (or any other) snap-in to it. To launch a mmc.exe instance as a different user use the following (changing the domain and username to that of your remote domain and user).
PS C:\> runas /user:savtechhgs\administrator /netonly mmc.exe
Enter the password for savtechhgs\administrator:
