DNS management software is computer software that controls Domain Name System DNS server clusters. Its main purpose is to reduce human error when editing complex and repetitive text based DNS server configuration files. Such files are often deployed on multiple physical servers. DNS service providers often deploy a complex mix of different types of DNS servers in their networks. In addition, different zone resource records must be provided to DNS clients based on the clients IP addresses usually ... has been to rely on databases and complex DNS management software to insure homogeneity and avoid single points of deployment errors. Before the availability of DNS management software, large DNS service providers relied on system administrators and in house custom collections of Perl or Shell computing Shell program scripts that provided some automation for managing large sets of DNS zones across a cluster of servers. Some DNS software includes these high level management tools. The most widely used DNS software, the Internet Systems Consortium ISC BIND DNS server software does not contain high level server cluster management software.

Onesource date June 2009 In computer networking , split horizon DNS , split view DNS , or split brain DNS is the facility of a Domain Name System DNS implementation to provide different sets of DNS information, selected by, usually, the source address of the DNS request. This facility can provide a mechanism for security and privacy management by logical or physical separation of DNS information for network internal access within an administrative domain , e.g., company and access from an insecure, public network e.g. the Internet . Implementation of split horizon DNS can be accomplished with hardware based separation or by software solutions. Hardware based implementations run distinct DNS server ... either multiple DNS server processes on the same hardware or special server software with the built in capability of discriminating access to DNS zone records. The latter is a common feature of many server software implementations of the DNS protocol cf. Comparison of DNS server software and is sometimes the implied meaning of the term split horizon DNS , since all other forms of implementation can be achieved with any DNS server software.

Microsoft RPC Microsoft Remote procedure call Remote Procedure Call is a modified version of DCE RPC . Additions include support for Unicode strings, implicit handles, inheritance of interfaces which are extensively used in Distributed Component Object Model DCOM , and complex calculations in the variable length string and structure paradigms already present in DCE RPC. Example The DCE 1.0 reference implementation only allows such constructs as size is len , or possibly size is len 1 . MSRPC allows much more complex constructs such as size is len 2 1 and even length is max & 0x7 0x7 , a common expression in DCOM IDL files. Use MSRPC was used by Microsoft to seamlessly create a client server model in Windows NT , with very little effort. For example, the Windows Server domain s protocols are entirely MSRPC based, as is Microsoft s Domain Name System DNS administrative tool. Microsoft Exchange Server 5.5 s administrative front ends are all MSRPC client server applications, and its MAPI was made more secure by proxying MAPI over a set of simple MSRPC functions that enable encryption at the MSRPC layer without involving the MAPI protocol. History MSRPC is derived from the Distributed Computing ... by Microsoft. DCE RPC was originally commissioned by the Open Software Foundation, an industry ... as DCE RPC at the time. The Microsoft proprietary technology, Distributed Component Object Model ... Network OLE , extends Microsoft s COM, and provides the communication substrate under Microsoft s COM application server infrastructure. It has been deprecated in favor of Microsoft .NET Framework . Microsoft donated Distributed Component Object Model DCOM to the Open Group . Fact date January 2008 The technology used by Microsoft in MSRPC is now deprecated and replaced by MPI.
