After you
install any of the Microsoft Application Center 2000 products that are listed in
this article, the node type is set to
4 (M-node,
Mixed). Additionally, a new registry entry with a value of
4 is created under the following registry key:
HKEY_LOCAL_MACHINE\System\CurrentControlSet\NetBT\Parameters\NodeType
This means that after the installation of Application Center, the
members of the cluster are using an M-node type of WINS name resolution. When
this usage occurs, the computer name is broadcast first, and then the DNS
server is queried. The installation of Application Center overwrites the
default key value of
8 (H-node type, hybrid) in the following registry key:
HKEY_LOCAL_MACHINE\System\CurrentControlSet\NetBT\Parameters\DhcpNodeType
This change may cause two problems:
Application Center 2000 installation makes this change in
the registry to guarantee good name resolution in an Application Center 2000
cluster.
If you want to change this, you can reset the node type back
to
Hybrid after the Application Center 2000 installation is complete.
However, you must guarantee that all the NetBIOS names of all cluster members resolve to
their management network adapters by using either WINS, Lmhosts, or DNS.
Additionally, you may also want to completely disable Application Center 2000
name resolution.
