On a NetWare 6.5 SP4 server:

When I enter dsrepair -a and go to Advanced Options, Global Schema
operations, Request Schema from Tree I get the following error:

ERROR: Unable to read local servers name and partition information.
Error -601.

I checked this on 5 different server of our tree and it is happening on
all of them.

The Novell Error Code reference lists many possible causes, but none of
them in relation to requesting a schema synchronization.

How do I trouble shoot this?

Thank you,
