You can use Rebuild on files that reside on Fileshare servers, but only with a limited range of Rebuild options. The format of the command line for using Rebuild through Fileshare is:
rebuild in-file[,out-file] -z:server-name {/l|/n} {/k|/u}
where:
| server-name | The name of a Fileshare server. All occurrences of server-name must refer to the same Fileshare server. |
You can also specify a Fileshare server without using the -z Rebuild option. The format of the command line for this is:
rebuild $$server-name\in-file [$$server-name\out-file] {/l|/n}
