The "NCP" name resolution
method on Novell Client for Windows 7 actually performs something
that was a hard-coded and non-optional behavior on the Novell Client
for Windows XP. The "NCP" name resolution method is what
ends up consulting the existing NCP connection table on the
workstation to determine whether we already have a connection to a
NCP server name or eDirectory tree name matching the name that is
being requested for resolution.
On Novell Client for Windows XP/2003 this was a test always performed before handing off the name resolution request to perform "an actual name resolution attempt" (via DNS, SLP, or whatever was enabled). In the Novell Client for Windows 7 this is implemented as "just another name resolution method", at peer with SLP, DNS, etc., as another source of where "we know of an address for that name" may come from.
It is not advisable to disable the"NCP" name resolution method in the Novell Client for Windows 7.
