LDHashDir not being created on preferred server

Hi All,

We have an issue which has started recently where the LDHashDir folders/files are not being created on any of the preferred servers.

Content replication shows that it completed successfully and all seems fine.

If i create a new package and then run content replication to get it out to preferred servers, the LDHashDir is not created

Running 9.6 with SP1

Any ideas anyone??
