I have to move servers and change the IP. During the process, there comes a point I need to log on using my cached domain credentials since I don't yet have network connectivity (we're not provided local admin accounts). Normally, I RDP into the server beforehand which caches the credentials so I can again logon while not having any connectivity to the network. Is there a way to script this with Powershell?
You'd probably want to test this to be sure, but I believe Windows should cache your credentials regardless of how you authenticated. Rather than trying to script a logon via Remote Desktop, try mapping a drive with "net use". Then you can simulate the IP change by unplugging the network cable of your test machine, and see if it lets you log on.
This command will authenticate to the server and prompt you to enter a masked password at a command prompt (or PowerShell console):
Initially, I have network connectivity and I use that in order to cache the credential for when I do not. Rather than using RDP to cache my credential, I would rather just run a script against a bunch of machines.
