Setting Primary and Secondary WINS Server Options

                        The information in this article applies to: 
               Microsoft Windows NT Workstation versions 3.5 and 3.51 
               Microsoft Windows NT Server versions 3.5 and 3.51 
SUMMARY 
If a Windows NT server is running the Windows Internet Naming Service (WINS) 
and is participating in WINS database replication on the network, special 
consideration must be taken configuring where the WINS server points to for 
it's own name resolution (this parameter is set in the Network section of 
Control Panel, in the Configuration section of TCPIP Protocol). 
It is highly recommended that a WINS server point to itself as Primary and 
Secondary WINS in the TCP/IP configuration. If another configuration is used, 
you may experience random instability in making certain network connections. 
MORE INFORMATION 
When any WINS enabled computer is booted it must register a variety of 
services with WINS. Commonly a computer has a Primary and Secondary WINS 
address configured in the TCP/IP setup. If the Primary WINS does not 
respond to the registrations, the computer tries the Secondary WINS. 
For additional information on the services that can be registered, please 
see the following article(s) in the Microsoft Knowledge Base: 
ARTICLE-ID: Q119495
TITLE     : List of Names Registered with WINS Service
Generally, most clients and servers should be configured with a Primary and 
Secondary WINS address, however caution must be taken with how a WINS server 
is itself configured. A WINS server eventually register its services in its 
own local WINS database, regardless of whether it points to itself or 
not (either Primary, Secondary, or none). Registering with itself and another
WINS server can cause problems when it comes to replication and renewal of 
these entries. 
For example, if you have a WINS server ("Srv1") that points to itself as 
Primary and points to another WINS as Secondary ("Wins2"). When Srv1 is 
booted, it usually tries to register its services before its own WINS Service 
is started. Since those registrations fail, it tries to register them at Wins2. 
If Wins2 is available, it accepts the registration requests. However, not all 
the services are registered at Wins2, because as these registration requests 
are made, Srv1 continues to check its local WINS service. Once the service 
is running, it switches back to it and continues registering locally. 
After replication has occurred between Srv1 and Wins2, both databases show 
this ownership: 
Srv1:  Owns his Srv1<20>, and Domain<1c> (if it is a domain controller)
Wins2: Owns all other Srv1 registrations, and also owns Domain<1c> from Srv1
This potentially problematic condition is referred to as "split registration." 
At this point, Srv1 has reverted to re-registering locally, however it takes 
a while before you can see it. Meanwhile, Srv1 and Wins2 are replicating the 
split registration mappings to other WINS servers. Eventually these replicas 
should be reconciled at the remote WINS (that is, the Wins2 replicas are 
replaced by the newer Srv1 replicas). However, before reconciliation is 
finished, client connection problems may have occurred, including the 
inability to connect to a WINS server that split its registration (in this 
example, Srv1), or the inability to resolve the domain<1c> name that Srv1 
registered. 
The exact conditions that lead to failure are varied. If your WINS servers 
are running Windows NT version 3.51 with Service Pack 4 (or greater), 
these conditions should only be temporary. However, the problem may be more 
severe depending on your replication scheme or if you are running pre- Service 
Pack 4 WINS servers. 
Another faulty configuration is setting a remote IP address (in this example, 
Wins2) as Primary while setting the local WINS (Srv1) as Secondary. In this 
case, Srv1 will eventually stop refreshing its NetBIOS lease at Wins2, and 
will begin registering locally. Depending on your WINS replication scheme, 
this may cause connection problems. 
WORKAROUND 
It is recommended that a WINS server point to itself as Primary WINS and as 
Secondary WINS. This will avoid split registrations and other problems. 
STATUS 
Microsoft has confirmed this to be a problem in Windows NT version 3.5 and 
3.51. We are researching this problem and will post new information here in 
the Microsoft Knowledge Base as it becomes available.
