From the the application manager server, try to access the \\DCname\Admin$\SysWOW64 share on the affected server.
Then try to copy a file over to that share location.
If a file is unable to be copied over to this location,
then this permissions issue is also the reason that the Administrative service is unable to be installed.
Resolve the permissions issue on the affected server and then try to install the Administrative service.
You may want to compare share permissions from a good server to resolve this issue.
