Forest Trust: Between two Forests – RED.COM & PINK.ORG

Image
  Scenario: In our organization for every location there are one single domain forest. For example, for Kolkata it RED.COM & for Jaipur it is PINK.ORG. Now the company management want to introduce SCCM & its main server should be in Jaipur (PINK.ORG) & a Site Server in Kolkata (RED.COM) for patch management & other deployments. Hence need to establish Forest Trust between two domains. Both domains have Forest & Domain Functional Level Windows Server 2008R2. Pix 01: Trust Challenges: £   In PINK.ORG (Jaipur) DNS, RED.COM (Kolkata) Primary Zone is there, it is created long back & several manual host entries are there. Primary Zone need to convert into Secondary Zone. £   Establish Two Way Forest Trust between PINK.ORG & RED.COM. To achieve this DNS name resolution between two forests is must & name resolution can be possible in different way –          i) Secondary Zone cre...

Google Chrome Bookmark & Homepage through GPO

Image
Goals: We need to create a GPO for Google Chrome Bookmarks & home page/landing page. Under the bookmarks, few URLs would be there. It will be easy for users to access these url/site. Also by home page – most useful/frequently open site can be set, so that when user open Google chrome, the page will be displayed first. Gyan: All policy setting for Group Policy Management Console are not readily available. Sometime to manipulate group policy settings for higher version OS (i.e. Screensaver for Windows 10) or third party application (i.e. Google Chrome),we need to download group policy setting supported files – admx (policy settings) along with adml (language suppot). Both files are stored into central storage repository, known as “ Central Store ”. For higher Windows it is “ PolicyDefinitions” – automaticall created when a DC built under C:\Windows\ Process: Incorporate Chrome GPO templates:         1.       To manage...

NTP Configuration for Time Sync

Image
Introduction : Windows Time Service(w32tm) with help of Network Time Protocol synchronize time with most reliable time sourced from top, if more than one referral time sources are available, then with help of NTP algorithm, NTP client select best one base on its ability to sync time. Stratum: External Time sources are defined according to its time accuracy/reliability by Stratum, lower the value, higher accuracy. Stratum 0 – Hardware Nuclear Clock, GPS Clock, Radio Clock. Stratum 1 connect to Stratum 0 & Stratum 2 with Stratum 1. These clocks are referral clock. The Stratum value define the synchronization distance to referral clock. Time Synchronization Process: Referral clock & our NTP server sync time with these referrals clock & its client sync with NTP Server time. The time difference between local clock & NTP is called “skew time”. Normally time service adjust time by changing the clock rate, but if the difference is too large to adjust, time servic...
