A customers FSMO role holder DC (DC-A) was infected with ransomware. However, the best back up they have is 1 month old from Windows Server Backup. The problem is that prior to infection there was some FSMO role organizing as DC-A was holding "most" of the FSMO roles, except the Schema and Infrastructure, which was held by DC-B. 3 Weeks ago those 2 roles were transferred from DC-B to DC-A, so all the FSMO roles could be held by 1 DC (DC-A). The problem is since DC-A has been restored back to the state it was a month ago, it now thinks DC-B is holding the Schema and Infrastructure role and DC-B thinks DC-A is holding those roles. How should I go about correcting this? Should I seize the roles from another DC? There's a total of 7 DC's, 1 in each of the 7 branch offices.
