New Administrator and synchronizing the folder

I synchronized a local folder with the server.
The server had a administrator.
I made a new administrator and transferred the rights to the folder.
Then I deleted the old administrator.
Now the windows client with the new administrator is not synchronizing the folder.
Do I have to upload it again?
Is there a way to synchronize the folder with the new administrator account?

Sorry for my bad English, i hope you understand what i mean :slight_smile:
