SYMPTOMS
If you create many IP address resources with the "Enable Netbios" option enabled, one or more resources may fail if the total number of Netbios enabled addresses on the system exceeds 64.

In Event Viewer, you may see the following event ID:

Event ID 1044

Source: Cluster Svc

Text: Cluster IP Address could not create the required Netbios interface.



CAUSE
This behavior occurs because Netbios has a table limit of 64 IP Addresses. In most cases, this number of IP addresses might be used for World Wide Web or FTP resources which do not require an entry in the Netbios table.



RESOLUTION
To resolve this behavior, allow the "Enable Netbios" option to be checked only on IP Address resources that have a Network Name resource dependent on it, or when the address is used with Netbios.

Note This behavior may also occur in Windows Server 2008 Enterprise and in Windows Server 2008 Datacenter



STATUS
This behavior is by design.
