The Best Damn Windows Server 2003 Book Period- P77:The latest incarnation of Microsoft’s server product,Windows Server 2003, brings many new features and improvements that make the network administrator’s job chapter will briefly summarize what’s new in 2003 and introduce you to the four members of the Windows Server 2003 family: the Web Edition, the Standard Edition, the Enterprise Edition, and the Datacenter Edition. | 726 Chapter 20 Planning Implementing and Maintaining a Name Resolution Strategy potentially improved by lengthening the amount of time an entry would persist in cache beyond the default 10 minutes. Preventing Split WINS Registrations A WINS server is also a WINS client to itself. A common configuration error is to specify a different WINS server to use as an alternate WINS problem with doing this is that during startup of the WINS server it will try to register its names with the WINS servers configured in the TCP IP properties. Because the WINS server service won t start until NetBT has initialized this causes the WINS server to attempt to register with the alternate or secondary WINS. However it will continue to try to register these mappings in the local WINS database. Once the local WINS database is available the WINS server will switch to it to register the remaining mappings. This results in what is known as a split registration where name mappings are registered in and owned by two different WINS servers. A split registration for WINS servers can cause intermittent problems with WINS name resolution. Performance Issues As mentioned earlier in the chapter a typical WINS server can handle WINS registrations and name resolution requests for up to 10 000 clients even if the WINS server has only modest amounts of CPU power and RAM. WINS traffic for each registration and name resolution request is relatively small. However a number of factors can affect the performance of WINS server. These factors include the presence of other services running on the WINS server the performance of database maintenance on the WINS server various WINS server settings and the flooding of the network with NetBIOS name registration requests. In this section we ll look at WINS server performance issues. Hardware Considerations Even a modestly powered computer can handle a large number of registrations and name resolution requests. However WINS can generate intensive CPU and
