DNS can be a tricky thing. Host names to IP mappings have to be propagated by DNS servers which can take some time to happen; in other words, DNS changes don’t happen immediately. Computers can cache DNS settings which can make things even more complicated. If you are a network administrator or computer programmer, DNS can present [...]
A very common issue which occurs when troubleshooting server related issues is DNS. There are many reasons for this, however the primary reason is the delay in propagation of DNS records. Often times a web application or site will require DNS records to function properly, but these changes either cannot be made prior to testing or do not propagate fast enough due to the nature of DNS servers.
When you create a new Active Directory Domain Services (AD DS) domain, the Active Directory Domain Services Installation Wizard installs the Domain Name System (DNS) server role by default. This ensures that DNS and AD DS are configured properly for integration with each other. Before you install AD DS and DNS on the first domain [...]
This tutorial will show you how to make a forest trust in Windows Server. A trust allows users in one domain to access resources in another domain. Trusts can be one-way or two-way. In a one-way trust, one domain’s users may access another domain’s resources, but not the other way around. In a two-way trust, [...]
Dynamic DNS services can be very useful for sites or servers with dynamic IP addresses. Most residential Internet providers will only provide you with a dynamic IP address, making it quite difficult to manage systems remotely. This problem can be remedied with the use of Dynamic DNS where a software client updates the DNS server [...]
What is a stub zone? Stub zones are a way for different DNS servers from different domains to communicate DNS information to each other. Technically speaking, a stub zone is a copy of a zone that contains only those resource records necessary to identify the authoritative DNS servers for that zone. When someone wants a resource [...]
Windows 2008 R2 offers some new features that improve DNS security. These new features include: DNS Security Extensions (DNSSEC) DNS cache locking DNS Socket Pool DNSSEC protects against forged DNS information, by using digital signatures. DNSSEC uses SSL to secure connections between DNS clients and servers. SSL encrypts the DNS query traffic between the DNS client and DNS server; it [...]
