i am having trouble promoting an additional DC at one of our sites. the site currently has an existing DC. i have DNS pointing first to the local site DC and secondary to hub location, and tried with both DNS pointing to hub DC. after going through the dcpromo wizard the configuration of AD begins for a few moments then errors out with the following error:
The operation failed because:
Active Direcotry could not create the NTDS Settings object for this domain controller CN=(FQDN of my DC) on the remote domain controller (my existing site DC). Ensure the provided network credentials have sufficient permissions.
"The data area passed to a system call is too small."
Now, of course i immediately thought of my rights. i double-checked for sanity's sake - i am still a Domain Admin (noone changed my rights). Another engineer with Domain Admin tried it as well and got the same issue.
i can't find anything with Google to answer this sufficiently. Any ideas as to what this error is pointing to?
