SYMPTOMS
When you use site connectors or multiple servers in a site where Internetwork Packet Exchange (IPX) is the only protocol that is used, if a Novell Bindery server does not exist, remote procedure call (RPC) fails between the two servers that are only using IPX.

Exchange Server RPC over Sequenced Packet Exchange (SPX) tries a getaddressbyname by using bindery lookup. This process fails because a Bindery server is not available; Service Advertising Protocol (SAP) lookup also fails because an SAP Agent is not present to respond.



RESOLUTION
To resolve this issue, use either of the following methods:
 * Enable Gateway Services for NetWare (GSNW) on the servers, and then make sure that you have a Netware server available that supports bindery functions. This method is the preferred method because bindery is more efficient than SAP.

-or-
 * Install GSNW and the SAP Agent on both servers. This method is not the preferred method because SAP is essentially a broadcast. However, this method is the only method you can use if a Bindery server is not available.
