I have an OES2 SP1 VM that's crashed & eDirectory has been corrupted - I get a -618 error when ndsd loads. From what people on the eDirectory forum have said, the way to fix it is to remove the server from the tree with ndsconfig -rm & then add it back into the tree.

This cool solutions article 15748 seems to be a good guide. It was also suggested that I ask here about possible ramifications of doing this on OES.

The server is largely just a file server, though it also runs Netstorage & has iPrint installed & configured, though I'm currently using a different server for printing.
