AFP corrupt and suddenly not working

Thank you JennC

for your hint to look under the shares -->settings - but unfortunately no successs

 ------

Are you disabling and re-enabling the FTP on the admin page's list of shares where you can change permissions?

• No until your hint I only tried under System-->Settings-Services
  Error:

  Service operation failed

  Unable to start or modify service

  Code 15002030001

• But, trying under shares gives also an error for Shares-->documents-->settings-->network access AFP on/off
  Error:
  Folder operation failed
  1002030001
  Commit failed

 If so, do you get the same error message when you enable FTP on another share? 

I also tried FTP (on/off) on another share than "Documents" - tried it on "Music" --> but unfortunately the same error.

Error:

Service operation failed

Unable to start or modify service

Code 15002030001

Thank you for thinking along - even if this doesn't give the solution - any further ideas to save my data and re-enabling AFP Service?

Yours NAS-SAN-NAS

(BTW - for me AFP is the Service in question as I need it in a MacOS Environment - so hope you didn't get me wrong - FTP is not the protocoll that I need to work)
