A few weeks ago the domain controllers in our Lab domain was attempted to be migrated from FRS to DFS. The domain is at Windows 2008 R2 functionality level and the DC's are on Windows 2019. When the migration was initiated with Dfrsmig this error appeared every 5 minutes when it tries to migrate SYSVOL:
DFSR was unable to copy the contents of the SYSVOL share located at C:\Windows\SYSVOL\domain to the SYSVOL_DFSR folder located at C:\Windows\SYSVOL_DFSR\domain. This could be due to<g class="gr_ gr_222 gr-alert gr_gramm gr_inline_cards gr_run_anim Grammar only-ins replaceWithoutSep" data-gr-id="222" id="222">lack</g> of availability of disk space or due to sharing violations.
Additional Information:
Sysvol NTFRS folder: C:\Windows\SYSVOL\domain
Sysvol DFSR folder: C:\Windows\SYSVOL_DFSR\domain
Error: 367 (The process creation has been blocked.)
Replication between the two domain controllers <g class="gr_ gr_265 gr-alert gr_gramm gr_inline_cards gr_run_anim Grammar multiReplace" data-gr-id="265" id="265">were</g> working without any issues. I've tried just about everything to fix the problem, adjusting permissions on the folders, running the Robocopy command manually (which did copy all the folders and files without error), deleting all GPO's not being used, running DCGPOFIX, removing all DC's except one, even performing a System State restore to a new DC (with an auth restore of AD and Sysvol). Rolling back the migration and starting again.<g class="gr_ gr_1532 gr-alert gr_gramm gr_inline_cards gr_run_anim Style replaceWithoutSep" data-gr-id="1532" id="1532">Nothing</g> has corrected the issue.
Has anyone seen this error or have any suggestions?
