NW 6.5.7 server, in DMZ.
Server runs GW Webaccess only. We don't use NW for file/print as we are an Active Directory shop. eDirectory ( strictly used for Groupwise domains.
This server holds no replica.
I've got three other servers on the internal network holding replicas.

Is it safe to delete the unknown objects in C1 and use NSS to update eDirectory?

Thanks in advance
