3  General discussions / General Discussion / Advice: What is the best way to learn network administration? on: December 27, 2002, 03:37:18 PM
A few suggestion, would be to set up multiple domain controllers, mutlple DNS servers, multiple WINS servers, a RIS server, and multiple subnets.

With multiple domain controllers you can work with replication scenarios, set up multiple sites, subnets, site links, site link bridges, and bridgehead servers, or put them all in one site and see how the KCC automatically configures replication.

With DNS servers you can configure different scenarios where, for instance, you use standard primary zones as the master name server to replicate zone transfers to secondary name servers. You can configure AD integrated zones to be the master name server to replicate zone transfers to standard secondary servers. You can configure a secondary name server as a master name server to replicate zone transfers to another secondary. Learn about the process of recursion, play with forwarding servers and forwarders. You can play with DDNS or manually maintaining resource records. Also, you can learn about configuring legacy clients for DDNS.

Same with WINS servers, you can configure them for different replication scenarios and configure them to integrate with DNS.

With the RIS server, practice unattended installs.

Another thing to spend a lot of time with, would be all the different Routing and Remote Access Service scenarios.

The most important thing is to have fun. Hopes this gives you some ideas. Wink

If you want to apply GPOs to objects, such as specific users, groups, computers, etc., you first have to put those objects inside a container. In other words, create an OU container, then add or move the objects you want to control through GPOs into the OU container, i.e., add or move the users, groups, computers, etc into the OU container. Next, you link the GPO to the OU container to apply GPO control over the objects contained inside the container by right clicking the OU container, choosing properties from the context menu, then choosing the Group Policy tab. From there you can edit the default Group Policy and apply it, add a Group Policy to apply, or edit and apply it, or create a new Group Policy and then edit and apply it to your objects contained inside the OU container.

Right clicking on an individual object, such as a user, group, computer, etc., and choosing properties will give you access only to that object's properties. There will be no Group Policy tab for you to access. Right clicking the container that the object is located inside of and then choosing properties from the context menu, gives you access to the Group Policy tab from which you can configure GPOs to control the objects.

Further, you can then use the ACLs of the specific GPOs to filter the GPOs that need to be applied down to individual objects contained in your OU container. To do this, click on the specific GPO you need to filter on the Group Policy tab to highlight it, then click on the properties button. This will bring up the GPO's properties, choose the Security tab to access the GPO's ACL. From the GPO's ACL, you can add or remove users, groups, or computers as needed and then apply the permissions required to filter the GPO onto the specific objects. Hope this helps. Wink

I'm not even sure if the RAM itself has integrity as it was taken from another 'dead' machine.

All help appreciated.
Thank You.


RAM needs to be compatible with your system. I recommend that you go to the Crucial site and check for compatibility. It could be the module you are using, especially if it came from a dead machine, is no good or incompatible. Test it on another machine.

Not entirely correct.

WINS is a peculiarity of the MS Windows family of operating systems. Other operating systems, such as Unix, use DNS only for name resolution and, indeed, if you are operating in a purely Windows 2000 environment, you too can decommission the WINS servers, as they will no longer be required. For reasons of better interoperability with the Internet, MS is moving towards a DNS only solution, as it's sole mechanism for name resolution.

In a Windows networking environment, each Windows workstation is configured as a client to a WINS server. This configuration is configured through the WINS tab in the Networking properties of the various Windows operating systems that are being used by the client workstations.

WINS clients make NETBIOS name query requests directly to WINS servers via unicasts or directed datagrams for NETBIOS name resolution. One of the reasons for this mode of communication is because routers do not forward broadcast. This mechanism also helps to significantly reduce broadcast traffic on the network.

In the situation when you are operating in a mixed environment with other non-WINS client operating systems, such as Unix, that are running a NETBIOS service that requires resolution for communication with remote NETBIOS hosts, you need to setup a WINS Proxy Agent for interoperability. A WINS proxy agent acts similar to a DHCP relay agent and the two are often confused. DHCP relay agents intercept client discover packets and relay them to DHCP servers for the purpose of address assignment only.

A non-Windows client operating system has no way of communicating with a WINS server, since a WINS server accepts NETBIOS name queries via unicasts or directed datagrams only. Therefore, to get around this issue, a WINS Proxy Agent can be setup on the same physical segment as the non-Windows clients. The job of the WINS Proxy Agent is to listen for NETBIOS name query broadcast and forward them to a WINS server on behalf of the non-Windows operating system. The WINS server either sends back a positive or negative response to the WINS Proxy Agent, which in turn caches those results and forwards them back to the non-Windows operating system where the NETBIOS name query originated. By default, the WINS Proxy Agent caches the positive or negative results for 10 minutes in case further inquires are made.

9  Microsoft (MCSE, MCSD, MOUS, MCAD) / 70-218 / Subnetting problem on: December 16, 2002, 05:10:47 PM
Here's the explanation I typed out for Cyberdude way back when.

Once computer 1 obtains and IP address via DNS, WINS, Broadcast, etc. it checks its Network ID to determine if the destination computer it wants to communicate with is local or remote. If it deems that it is remote, it sends out a special broadcast on the local wire that can be answered only by the router serving the default gateway role. The router sends computer 1 back its MAC address and communication can proceed.

On the other hand, if computer 1 deems that the computer it wants to communicate with is local, it sends out a local broadcast on the wire to obtain the MAC address for a computer located on the same local physical segment. Only a destination computer located on the same local physical segment can return its MAC address in response to this broadcast. A router cannot and will not respond to this particular broadcast.

When computer 1 is sending out this local broadcast, no computers located on the same local physical segment are able to respond, since computers 3 & 4 are actually located on a different physical segment. What is happening in this scenario, is computer 1 is seeing computers 3 & 4 as being local, since if we break down their IP addresses into binary, the first 18 bits corresponds to its own subnet mask, which is the left most 18 bits.

Subnet 1: 10010011 00111100 101
Subnet 2: 10010011 00111100 100
Subnet 3: 10010011 00111100 110

10000000 to 10111111 = 128 to 191 in third octet using /19 subnet mask is seen as being local by computer 1.

Therefore, any IP addresses that fall in the range of 128 to 191 in the third octet and using a /19 subnet mask will be seen as local by computer 1, regardless if its located on the same local physical segment or not, and any broadcast it sends out to the local wire to obtain the MAC addresses for computers 3 & 4 is destined to fail, because, again, in this scenario computers 3 & 4 are actually located on a different physical segment. You must also remember to keep in mind that the router will be unable to respond to this broadcast.

Further, computer 1 will be able to communicate successfully with computers 5 & 6, since their IP addresses in the third octet fall outside the 128 to 191 range, and it will see computers 5 & 6 as being remote.

147.60.218.57 /19 = 10010011 00111100 11011010 00111001
147.60.197.66 /19 = 10010011 00111100 11000101 01000010

Looking at your bmp images, the SRVs look good.

Those numbers you are seeing in the Sysvol folder are GUIDs or Global Unique Identifiers, a type of class identifier, which is a 128 bit number guaranteed to be unique on the network; they are assigned to objects when they are created.

Everything looks good! Looks like you're making progress!

As Jeff has mentioned, the two forest thingy is funky. Better to set up one forest with two domains in your setup.

One of the shortcomings of Windows NT 4.0 was there was no easy method of demoting your domain controllers to member servers. You basically had to start from scratch and completely reinstall the operating system to demote a domain controller to a member server. A major advantage of Windows 2000 is the ability to easily promote your member servers to domain controllers and then demote them back to member servers again as often as you like and as often as you need. Indeed, I encourage you to practice these two operations often, especially during the initial learning stages, until you become very familiar with the procedures.

A few tips on DNS and Active Directory would be to use Active Directory Integrated Zones, since they are the easiest to setup and administer among numerous other advantages. To check if your zones are Active Directory Integrated, open up the DNS manager, expand forward lookup zones, highlight and right-click the zone that represents your domain, choose properties from the context menu, the zone properties will come up. On the general tab where it says type, make sure it says Active Directory integrated. If it doesn't, click the change button and change it to Active Directory integrated by choosing the Active Directory integrated radio button and clicking OK. Now back at the general tab, make sure allow dynamic updates is set to yes.

A few other things to check would be the presence of correct Service (SRV) Resource Records. Click the forward lookup zone that represents your domain. In the right paine you should see four folders in descending order beginning with _msdcs, _sites, _tcp, _udp. You should also find a SOA resource record that will indicate the incrementing serial number, primary server, and the responsible person. A NS resource record follows indicating the server name, then various Host (A) records representing other resources on your network.

Next, I would check for the SYSVOL and NETLOGON shares. You can do this by going to the computer management snap-in, expanding Shared Folders, then clicking Shares, or if you prefer, go to a command prompt and type "net share" and enter will accomplish the same thing. Check the Active Directory Users and Computers snap-in and make sure that your domain controller has been placed in the Domain Controllers container. Another thing I test is the Directory Services Restore Mode boot option to make sure that not only does this option work, but it works with the password that you supplied during the installation of Active Directory. It's always a good idea to make sure that your recovery options will work in the event you will have to use them. Reference the following link for an easy step by step.

Here's some pointers to help you out with DHCP. When configuring the IP Address Range in the DHCP New Scope Wizard, in the Start IP address field use 192.168.1.1; in the End IP address field use 192.168.1.254, then click next. In the Add Exclusions Start IP address field use 192.168.1.1 and in the End IP address field use 192.168.1.10, then click add. Click next and configure the lease durations or leave at the default values, then configure any DHCP options that are require, (i.e., DNS, WINS, etc.), activate the scope, and when you are finished with the wizard, confirm that the scope is activated, then go ahead and authorize the DHCP server.

The first address the DHCP server will issue to your clients will begin with 192.168.1.11. The range of excluded addresses 192.168.1.1 to 192.168.1.10 will never be issued to clients on your network, as they have been excluded. These referenced excluded addresses, (192.168.1.1 to 192.168.1.10), are the ones that should be used to statically configure your domain controllers, member servers, routers, printers, etc.

Sorry! That's all I have time for right now. I got to leave. I'm going duck hunting. I'll try to help you out with the DNS problems when I get back. Good luck!

I've said it before, and I'll say it again. If you're preparing for the 216 exam, you need to get yourself a 221 book and go through it too. That whole new realm of configuration challenges you mention, are covered by the 221 material. Wink
