FIX: Domain In Windows 2000 Dfs Server Mode


Recently, some of our users encountered an error code with domain based dfs in Windows 2000 server mode. This issue occurs for a number of reasons. Let’s discuss it now.

g.Domain-based DFS Root integrates with Active Directory and thus enables DFS topology replication across the entire domain (but not folder duplication unless you tilt it specifically for replication). The domain-based DFS root must be hosted on a real domain member server.

When creating a fully-qualified namespace, you must choose one of two types of additional namespaces: a stand-alone namespace, just about any, or a domain-based namespace. If you choose a domain-based namespace, you must also choose a namespace mode: Windows 2000 Server Mode or Windows Server 2008.

Select Namespace Type

Select a stand-alone namespace if any of the following conditions apply to your environment:

  • Your agency does not use Active Directory Domain Services (AD DS).
  • Do you want to increase the size of the namespace witha failover cluster of any type.
  • You should create a good unified namespace with more than 5000 DFS folders in the domain because it does not meet the requirements for a domain namespace (Windows Server 2008 mode) as described later in this skill section / li>

Select a domain namespace if the following conditions apply to your entire environment:

  • You want to guarantee the namespace number using multiple namespace servers.
  • You want to hide this special namespace server name from users. This makes it easier to replace the namespace server or move the namespace to another server.

Select Domain Based Namespace Mode

When choosing each domain namespace, you must decide to use Windows 2000 Server mode, or perhaps Windows Server 2008 mode. Windows Server 2008 mode provides enumerated support based on access and increased scalability. The domain namespace introduced in Windows 2000 Server is referred to only as “Domain namespace (Windows 2000) “.

To use the Windows Server 2008 style, the domain and namespace must meet the following minimum requirements:

  • Forest applications are superior to Windows Server 2003 and even at the functional forest level.
  • Domain is using a higher Windows or Server 2008 domain level.
  • All namespace servers are Windows Server 2012 R2, Windows Server 2012, Windows Server 2008 R2, and Windows Server 2008.

If your environment supports this idea, select Windows Server 2008 mode when creating new domain namespaces. This mode provides additional functionality or scalability, and prevents possible namespace migration from Windows 2000 Server mode.

For more information about migrating your own namespace to Windows Server 2008 mode, see A Migrating a Domain-Based Namespace to Help You in Windows Server 2008 Mode .

If your environment does not support domain namespaces, Windows Server 2008 mode, use the existing Windows 2000 Server mode for the namespace.

Compare Namespaces And Modes

Namespace type and mode properties a are described in the following table.

property Standalone namespace Domain namespace (Windows 2000 Server mode) Domain namespace (Windows Server 2008 mode)
Namespace path Servername RootName NetBIOSDomainName RootName
DNSDomainName RootName
NetBIOSDomainName RootName
DNSDomainName RootName
Location of namespace information Personal computer registry and memory cache related to namespace servers Above in AD DS and memory cache on each individual namespace server AD DS and namespace server cache
Namespace size guidelines The namespace can now contain over 5000 folders with targets; recommended limit – 50,000 target versions All namespace objects in AD DS must be less than 5 megabytes (MB) in size for compatibility with non-Windows Server ’08 domain controllers. This means no more than 5,000 assignment records. The namespace easily contains over 5000 target folders; recommendthe maximum limit is usually 50,000 target folders
AD DS Functional Level Minimum Violations AD DS may not be required Windows 2000 Windows Server 2003
AD DS Dominion Minimum Functional Level AD DS is never required Windows 2000 mixed Windows Server 2008
Minimum Secured Namespace Servers Windows 2000 Server Windows 2000 Server Windows Server 2008
Access-based enumeration support (if enabled) Yes, includes Windows Server 2008 namespace server No Yes
Supported types for making namespaces available Create a kind of stand-alone namespace in case a good reliable cluster fails. Use multiple namespace servers for frequent namespace hosting. (Namespace servers must be in the same domain.) Use a namespace variable server to host the namespace. (Namespace servers must be in the same domain.)
SupportHow to use DFS Replication to replicate target folders Supported when hosted in an AD DS domain Supported Supported

To check the size of a meaningful namespace, right-click the namespace in a specific tree in the DFS Management Console, select Properties, and then view the computer’s namespace in the Namespace Properties dialog box. For more information about the scalability of DFS namespaces, see File Services Microsoft.



How do I find my DFS server domain?

2 reviews. Go to DFS Management Console, finally expand Namespaces and find the namespace whichyou are looking for. If you don’t, right click on Naemspaces and select Add Namespaces when you want to browse and select the namespace you are looking for. Once the person has a visible namespace, just tap on it.

Does DFS need to be on a domain controller?

Reduce data-driven shared resources by creating multiple DFS link destinations. DFS Data Replication is not ordered, but is recommended for dataset redundancy. Without Replication, DFS only provides this common namespace for shared resources. Do not host DFS shares on room controllers (DCs).

Should all domain controllers be DFS namespace servers?

This may sound tempting, but domain controllers should not disable the DFS Namespace service. Clients need to access the Domain Controllers DFS service to enumerate trusted domains, retrieve current domain controllers, and process requests to navigate to the Dominion namespace.
