Why does NetBoot Desktop Admin application produce the following error message? "Unable to save changes. File system error, sorry a system error occurred. -43"

The error message is usually caused by a server crash while using the NetBoot Desktop Admin application from a client. This error message occurs after the system is restarted and NetBoot Desktop Admin is restarted from a NetBoot client.

There is no workaround for this condition. Your only option is to reinstall Mac OS X Server and the NetBoot software.
