Well, the intraforest domain migration was an epic fail. I showed up on site, RDP'd into the target DC, and ran the ADMT utility, selected the group migration wizard, selected the source domain, <any domain controller>, selected the target domain, and selected HDQ-DC, but received the following error message:
"The specified domain either does not exist or could not be contacted."
So, I confirmed that I could ping the source DC, BRDC1.brick.sca.local, and I also confirmed that I could RDP into it. I checked that DC locally, and confirmed ADDS and DNS services were running. So I thought, let me check the trusts.
From the HDQ-DC DC, I opened AD Domains and Trusts and right clicked on the parent domain and noticed the trust. Remove was greyed out. I selected properties and confirmed the trust type is set to Parent-Child. I clicked on Validate, and recv'd the following error:
"Windows cannot find an AD Domain Controller for the Brick. sca.local domain. Verify that an AD Domain Controller is available and try again."
From the Brick DC, I open AD Domains and Trusts, and right clicked on the parent domain and received the following error in the properties box:
"The AD Domain Services object could not be displayed. Information for this object is not currently available possibly due to a network or AD Domain Controller failure."
I then, right clicked on the child domain and selected Validate. I entered my Enterprise Admin credentials and recv'd the following error:
"The outgoing trust was successfully validated. The Secure Channel (SC) reset on AD Domain Controller \\DC4.sca.local of domain sca.local to domain Brick.sca.local failed with error - There are currently no logon servers available to service the logon request."
I selected Yes, to reset the trust passwords and it errored out with "The trust cannot be repaired because there are currently no logon servers available to service the logon request."
Sorry for posting such a long thread, but I wanted to provide experts with the steps that I had taken and the errors that occurred at the exact points in which they occurred. Please, in simplest of terms, provide me with steps on what I need to do to resolve this.
What do I have to do in DNS? What do I have to do in Domains and Trusts? What do I have to do in Sites and Services?
