We recommend using no more than 5,000 links in a domain-based namespace to prevent the DFS Active Directory object from exceeding 5 MB. Domain-based Root Referral Cache A domain-based root referral contains a list of root targets that host a given domain-based namespace.

Dfs Share Not Accessible How can I delegate authority to manage a DFS namespace? How can an employee kindly decline to participate in an office potluck?

A DFS client requests a domain controller referral from a domain controller (in the client’s domain) to determine which domain controllers can provide a referral for a domain-based namespace. Using the previous figure as an example, when default target selection is enabled, DFS places the target servers in the referral in the following order: Default Referral Order If no same-site
Root servers that run Windows 2000 Server or Windows Server 2003 and that are not domain controllers cannot determine a DFS client computer's site when the restrictanonymous registry entry is set Dfs Share Access Denied For example, if a link target is running Windows NT 4.0 or a non-Windows operating system, DFS can determine the target’s site using its IP address.

If you are using File Replication Service (FRS) to replicate DFS link targets, any NTFS permission changes you make on one member of the replica set replicate to other members. These folders, called link folders, are actually reparse points, and they display the following error message if you try to access them on the local server: E:\RootName\LinkName is not accessible. remoteServerName. This situation occurs when the only domain controllers running Windows 2000 Server are in the site of the DFS root server, or when no domain controllers are in the site of
