My Current Domain Network

Hi All,

I thought that it might be a good idea to show you my current domain diagram for my 291. At the moment as you know I have a domain and a child domain, both have a wsus server the child domain wsus is a downstream server. This network will at the moment be used to study DNS,DHCP and wsus. I’ve bought a dell powerconnect 3024 switch from ebay for £20 which I will set up some vlans on it to experiment with routing and relays etc.

Heres the linky for my network

have a look at the powerconnect tags for links to my other posts about the switch.

If you are interested I used an open source program call “dia” to create the diagram, I know the images etc are not very polished but it gets the point across

DNS tutorial

Hi all,

I’ve written a short tutorial on DNS resolution, its by no way complete yet as im still learning the subject so may have the odd error in it. However I have found a great little technet artile which the link is included in the document to explain the difference of iterative and recursive resolution.

DHCP DORA

Well I’ve been reading up on the DORA process for DHCP and have created a little tutorial on how clients get IP addresses in the first place. As normal comments and suggestions welcome.

70-291


Well, I've got the sybex 291 book in front of me and am about to embark on learning enough to slay the beast. The initial chapter is all about the OSI model. I have studied this model before so am aware of it but I think it would be very beneficial if I go in to great depths on all the topics covered in the 291.

I may start my learning the model and then writing a tutorial about it to help me out.

IIS

Well over the past couple of days I’ve been having a look into iis and at this point I’ve discovered that iis administration bleeds over into the 291 exam, in the same way alot of admin tasks from the 270 exam can be taken in some way or another to the 290 exam.

To start with the host header values you set for iis and multiple websites must be accompanied by a DNS entry to point to the iis server and the host header value sorts out what to present back to the client. so this way you can have hundreds of websites on the same server and it will always know what to serve a client.

Now a work related item, I found an interesting and time saving tool the other day. The problem Im having is that in our work place it appears folder access has always been granted to individual users which sometimes has resulted in a huge list of 20-30 users in the netware DACL. This I suppose isnt really a problem but it looks untidy and could be a security risk. So what I’ve started doing is when coming across such folders with a ridiculous amount of users assigned to it, is I’ve created a group for the folder and added the users into it to help me administer them easily.

However this can take an absolute age because of the sheer number of users involved and there is no way of specifiying (that I can find) just usernames to add to the group, so you have to add them by roaming around all the OU’s in console one, which itself can take a long time.

 

However this tool helps me loads as it allows me to enter just logon names in a text file and import them into the newly created group. firstly it will ask you for the group name and will ask you to confirm if thats what you mean (incase there are two or more similar ones) and then a text file to import. it saves me a bundle of time.
