How to integrate Windows 7 to a domain using NETDOM
Sep 28th
Netdom.exe is a command line tool that is built into Windows Server 2008 and Windows Server 2008 R2. It is available if you have the Active Directory Domain Services (AD DS) server role installed. It is also available if you install the Active Directory Domain Services Tools that are part of the Remote Server Administration Tools (RSAT).
NETDOM is not installed by default in Windows 2000/XP/2003 so you have to install it through the Support Tools /Resource Kit to get your hand on it, also you have to install the correct version of NETDOM specified for your operating system. (more…)

01. Which two conditions have favored adoption of 802.11g over 802.11a? (Choose two.)
- 802.11a suffers from a shorter range than 802.11g.
- The 2.4 GHz frequency band is not as crowded as the 5 GHz band.
- 802.11a is more susceptible to RF interference from common commercial items.
- 802.11a uses a more expensive modulation technique than 802.11g.
- 802.11g is backward compatible with 802.11b, but 802.11a is not.
02. Which two statements concerning network security are accurate? (Choose two.)
- 802.11i uses 3DES for encryption.
- Open authentication uses no client or AP verification.
- The 802.11i protocol is functionally identical to WPA.
- 802.11i incorporates a RADIUS server for enterprise authentication.
- A wireless client first associates with an AP and then authenticates for network access. (more…)

01. Refer to the exhibit. Which three statements describe the network design shown in the exhibit? (Choose three.)
- This design will not scale easily.
- The router merges the VLANs into a single broadcast domain.
- This design uses more switch and router ports than are necessary.
- This design exceeds the maximum number of VLANs that can be attached to a switch.
- This design requires the use of the ISL or 802.1q protocol on the links between the switch and the router.
- If the physical interfaces between the switch and router are operational, the devices on the different VLANs can communicate through the router. (more…)
CCNA Exploration 3 LAN Switching and Wireless – Chapter 5 Exam

01. Refer to the exhibit. All switches in the network have empty MAC tables. STP has been disabled on the switches in the network. How will a broadcast frame that is sent by host PC1 be handled on the network?
- Switch SW1 will block the broadcast and drop the frame.
- Switch SW1 will forward the broadcast out all switch ports, except the originating port. This will generate an endless loop in the network.
- Switch SW1 will forward the broadcast out all switch ports, except the originating port. All hosts in the network will reply with a unicast frame sent to host PC1.
- Switch SW1 will forward the traffic out all switch ports except the originating port as a unicast frame. All hosts in the network will reply with a unicast frame sent to switch SW1. (more…)
Active Directory integration with Samba for RHEL/CentOS5.5
Sep 4th
I’ve been asked to develop an enterprise level of complex network servers that can provide many services including mail server, ftp, web server, file server, print server, backup server, roaming profiles and user’s home directory.. etc. The client demanded at least one Linux machine regardless of the service running on it. I’ve decided to run the web server (Apache) on it associated with the FTP server for managing the web pages contents, so I had to come out with a solution to join the Linux server to the Domain Controller (which is windows server 2003) as a member server.
It is true that any number of Samba servers can normally be set up in a Windows network without joining them to a domain. However, advantages of domain membership are central management, authentication and single sign-on. So once you’ve done with all the configuration and successfully joined the server to the DC you can use the same account name and password to log on to your Linux or Windows machine as well as the network administrators will be able to logon to the machine with their administrator credentials.
