Servers: OES2 Sp1 linux and OES nw65sp8.

I used the dnipinst -r and then dnipinst to move the locator object
to a new context. but then when the schema is extended again its not
possible to assign dhcp services to a Linux oes2 server again.
seems that they missed addning the oes2 sp1 schema to dnipinst

Howto reextend the schema for oes2 sp1 ?
