What are the common mistakes by network administrators during network data backup and restoration?

What are the tips to overcome such problems and avoid a big disaster because the data is the most valued asset in any business and its security and confidentiality is very important to run a successful business? 

I recently had a wireless router installed for my home network. I didn't know much of its security configuration as the DSL provider technicians did the whole installation and they only asked me to give a shared key 'passphrase'.

I recently bought a Linksys 4 Port Wireless Router and I would like to know how to configure its mac filtering settings to be able to setup a more secure wireless network and to limit the devices connected to my network?

I have built a small home network via cable, 1 server and 3 users. Whenever I share some folder and give access rights to other users, it displays an error message, “Access Denied”.

I’ve discovered that if I share a folder on any drive other than C, it works fine but some folders shared on C do not give access rights, even though rights are granted upon sharing.

Please tell me why is it so?

What are the most common problems with a networking system and how can they be resolved?

I have more than 40 computers connected to the network on my dormitory house. We used unmanageable switch to connect all of computers.

We have planned to upgrade using router. We think about using mikrotik or juniper router. What are pros and cons of each?

Hi folks,

please allow me to post my problem here in Microsoft Office Groove File Sharing. An error message appeared on my screen and informed me about some compatibility issue. See the screen shot I pasted, below.

Microsoft Office Groove

Groove File Sharing workspaces are not supported on 64 bit operating system.

This problem all started when I shifted to Windows 7 Pro 64bits. Earlier with 32bits there was no problem. I also saw somebody using Microsoft Office Groove File Sharing on a Windows 7 Pro 64bits.

Hi All,

How to find a remote IP (Internet Protocol)?

Thank you.

My router is Linksys and I want to know which is better to use – 64-bit wep or 128-bit wep.

I really don't get the difference, if they are compromised its still the same problem.

Hi,

My Name is RobertGart, an instructor in Computers. I managed the networking side of our school and I used IPCOP software for our Firewall.

One of the features I configured, is the DHCP server and it works fine. Our admin wants me to block unwanted sites in our network and I know that IPCOP is capable of blocking sites. IPCOP has various add on's. Although, it's a great firewall, it seems to me that these add on's should be incorporated into the basic IPCOP package.

Can anybody help me what add on's are needed for blocking site? and how to configure it?

Thanks.
