Refresh Cached AD Credentials through VPN to Trusted Domain

us flag

Our infrastructure has 2 domains, one is on premises and the other is in AWS, both Windows Active Directory. There is a one way trust setup so that the AWS domain can authenticate resources based on on-premises domain users, but not the other way around.

I work remotely and have joined my work computer to the on-premises domain using the on-premises VPN, but I have no reason to connect to the on-premises VPN for day-to-day tasks. All of my work is done using AWS resources but I am required to use and authenticate with a user account from the om-premises domain.

The cached credentials from the intitial domain connection on the work computer work fine for some time, but eventually stop working causing the trust relationship to break and I have to leave and rejoin the domain.

The network team has infomred me that the only way to prevent this is to routinely connect to the on-premises VPN to update the cached credentials.

Is there any way to update my cached credentials through the AWS VPN and not the on-premisis VPN?

Your user account credentials is not related to the computer trust relationship breaking.

So network guys are wrong? How do I keep the trust relationship from breaking?

Anyone saying that a user account can cause a computer account trust relationship to break is incorrect.

that's great to know, but what's the solution to preventing it?

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
