The Scenario
I am attempting to migrate a server from one domain to another using the Microsoft ADMT (Active Directory Migration Tool). The ADMT is running as a Domain Admin account on the destination domain.
The Problem
ADMT reports the following error when attempting to run the pre-check
“ERR2:7674 Unable to determine the local path for ADMIN share on the machine ‘<server_fqdn>’. rc=-2147024891”
The Pre-check fails and the migration tasks stops.
The Solution
Add the user account you’re logged in to the ADMT server (and running the migration task) as to the local admin group of the server you are trying to migrate. ADMT will detect the change within 1-2 minutes.
