IPX name resolution services (Bindery and NDS)
Domino servers can use either Bindery, NDS, or both for IPX system name-to-IPX net/node address resolution (IPXs NCP protocol services). Bindery services are dynamic in nature. As such, any loss of communication between the Domino server and the NetWare server or other NetWare server can cause loss of access. NDS objects once initialized are static in nature, so as long as the system can access the NDS tree, it can locate the Domino server.

Note An IPX node address is often the same as the MAC address of the network adapter card. When crossing bridges between Token-Ring and Ethernet or between Token-Ring and FDDI there may be issues where the MAC address and the IPX node numbers are not consistent with the NDS tree objects of the Domino servers. When Notes clients or Domino servers are accessing a Domino server on the other side of the bridge via NDS, they must have consistent MAC and node addresses from their network segment ({Least/Most Significant Bit order} LSB/LSB or MSB/MSB, not MSB/LSB or LSB/MSB).

The following table offers some basic guidelines in using Bindery and NDS services:

NetWare 4.1, 4.11 or 5.0 (Bindery and NDS)*XX
*Domino servers can support only one Bindery context entry that the Notes client and/or Domino server systems can access.

** Recommend filtering Bindery service advertising protocol (SAP) services over WAN links if there are any Bindery-only devices present on the network.
