User-ID service account attempting to login to the wrong domain?

[jgorman]

To start, the User-ID is working fine servicing our Corporate VPN, however...

We have multiple domains in our environment, production, corporate and staging. None of them have trusts between them and the User-ID Agent is only installed on our Corporate Domain, domain controller. The below error messages are appearing on pretty much all of our servers in the Production domain. We would like to know why the User-ID Agent service account user is attempting to log into our servers in the Production domain from our Corporate Domain controller, and how to keep this from happening. Any help would be greatly appreciated.
