Windows Server 2003 Active Directory and Security questions

I am trying to create a new universal user group. Why can’t I?  Universal groups are allowed only in native-mode Windows Server 2003 environments. Native mode requires that all domain controllers be promoted to Windows Server 2003 Active Directory. What’s the difference between local, global and universal groups?  Domain local groups assign access permissions to global domain groups for local domain resources. Global groups provide access to resources in other trusted domains. Universal groups grant access to resources in all trusted domains. What is LSDOU?  It’s group policy inheritance model, where the policies are applied to L ocal machines,  S ites,  D omains and  O rganizational  U nits. Why doesn’t LSDOU work under Windows NT?  If the  NTConfig.pol  file exist, it has the highest priority among the numerous policies. Where are group policies stored?  %SystemRoot%System32\GroupPolicy What is GPT and GPC?  Group policy template and group policy container. Where is GP

TCP/IP: DNS, WINS, & DHCP

DNS and WINS are really for doing two different (but similar) things. Second, each has been co-opted to assist the other in some cases -- and as a last resort. Literally  Domain Naming System (DNS) servers, resolve Domain Naming System names to IP addresses.  Sounds redundant, but technically it is almost literally true (not quite for you advanced people) that an IP host has NO NAME; it has a DNS name only by virtue of the DNS servers or by convention. Windows Internet Naming Services (WINS) servers resolve NetBIOS names to IP addresses . NetBIOS names ARE a feature of the network node (or host machine). The NetBIOS protocols require that NetBIOS nodes 'defend' their name from other machines attempting to use the same name. Likewise,  a 'host' file resolves DNS names to IP addresses  while  an 'LMHOST' file resolves NetBIOS names to IP addresses. So you can see a 1-1 mapping of DNS server to host file, and WINS server to LMHOSTS file. The order of use of these

How To Install and Configure a File and Print Server in Windows Server 2003

Install File and Printer Sharing By default, a Windows Server 2003-based computer is installed with Client for Microsoft Networks, File and Printer Sharing for Microsoft Networks, and TCP/IP. NOTE : You can view these services in the properties for the local area connection. You can create a Windows Server 2003 file server and print server manually, or you can use the wizards that are provided in the Configure Your Server Wizard administrative tool. How to Install a File Server on Windows Server 2003 by Using the Configure Your Server Wizard Click  Start , point to  Administrative Tools , and then click  Configure Your Server Wizard . Click  Next . Click  Next . Click  File server  in the  Server role  box, and then click  Next . On the "File Server Disk Quotas" page, configure any quotas you need to control disk-space usage on the server, and then click  Next . On the "File Server Indexing Service" page, click the indexing configuration that is appropriate fo

How to install and configure a DHCP server in an Active Directory domain

Introduction Dynamic Host Configuration Protocol (DHCP) is a core infrastructure service on any network that provides IP addressing and DNS server information to PC clients and any other device. DHCP is used so that you do not have to statically assign IP addresses to every device on your network and manage the issues that static IP addressing can create. More and more, DHCP is being expanded to fit into new network services like the Windows Health Service and Network Access Protection (NAP). However, before you can use it for more advanced services, you need to first install it and configure the basics. Let’s learn how to do that. Installing Windows Server 2008 DHCP Server Installing Windows Server 2008 DCHP Server is easy. DHCP Server is now a “role” of Windows Server 2008 – not a windows component as it was in the past. To do this, you will need a Windows Server 2008 system already installed and configured with a static IP address. You will need to know your network’s IP add
