| The C: drive partition on my server is low on disk space. My current IT Support provider tells me that I need to replace my server. Is there any alternative? | | | This is an issue we see on a regular basis. Typically, the C: partition is 12Gb or smaller. However, we usually find that there is plenty of free space on another partition on the server.
It is possible to remove some of the free space from the second partition and reallocate this free space to the C: partition. This procedure requires specialist tools and many of our competitors prefer not to do it. Techsure are often subcontracted by other IT Support companies to carry out this procedure on their behalf.
In today's economic climate, businesses must make better use of the equipment they already have and should not rush into replacing a server when it's useful life can be extended.
Contact Techsure on 01 8249049 if you would like us to assess your server's suitability for this procedure. The assessment can be done instantly via remote connection. | | 5. | I am running out of space on the C: drive of my new PC. What can I do to retrieve more space? | | | 1. Run Disk Cleanup.
2. Defragment your disk.
3. Compress Folders.
4. Move Swap File.
5. Reduce Space For System Restore.
6. Remove Backup Folders.
7. Remove SQL Server Setup Log Files. | | 6. | How Many Computers Can Share a WiFi Network? | | | Most WiFi wireless access points / routers claim to support up to 255 connected devices. Access points and routers support a small number (usually either 1 or 4) of wired Ethernet and the rest via wireless connections.
Connecting 255 computers to a single WiFi access point, while theoretically possible, is not recommended. Performance of such a network will be very poor. Install multiple access points instead to distribute the network load. By adding more access points to the network, effectively any number of computers can be supported (though the network becomes progressively more difficult to manage).
On a home network, while dozens of computers and other devices may connect to the router, the performance of a shared Internet connection will quickly degrade as more computers access the Web simultaneously. | | 7. | What Is a DNS Server? | | | A DNS server is any computer registered to join the Domain Name System. A DNS server runs special-purpose networking software, features a public IP address, and contains a database of network names and addresses for other Internet hosts.
DNS servers communicate with each other using private network protocols. All DNS servers are organized in a hierarchy. At the top level of the hierarchy, so-called root servers store the complete database of Internet domain names and their corresponding IP addresses. The Internet employs 13 root servers that have become somewhat famous for their special role. Maintained by various independent agencies, the servers are aptly named A, B, C and so on up to M. Ten of these servers reside in the United States, one in Japan, one in London, UK and one in Stockholm, Sweden.
The DNS is a distributed system, meaning that only the 13 root servers contain the complete database of domain names and IP addresses. All other DNS servers are installed at lower levels of the hierarchy and maintain only certain pieces of the overall database.
Most lower level DNS servers are owned by businesses or Internet Service Providers (ISPs). For example, Google maintains various DNS servers around the world that manage the google.com, google.co.uk, and other domains. Your ISP also maintains DNS servers as part of your Internet connection setup.
DNS networking is based on the client / server architecture. Your Web browser functions as a DNS client (also called DNS resolver) and issues requests to your Internet provider's DNS servers when navigating between Web sites.
When a DNS server receives a request not in its database (such as a geographically far away or rarely visited Web site), it temporarily transforms from a server to a DNS client. The server automatically passes that request to another DNS server or up to the next higher level in the DNS hierarchy as needed. Eventually the request arrives at a server that has the matching name and IP address in its database (all the way to the root level if necessary), and the response flows back through the chain of DNS servers to your client.
Computers on your home network locate a DNS server through the Internet connection setup properties. Providers give their customers the public IP address(es) of primary and backup DNS servers. You can find the current IP addresses of your DNS server configuration via several methods:
* on the configuration screens of a home network router
* on the TCP/IP connection properties screens in Windows Control Panel (if configured via that method)
* from ipconfig or similar command line utility | | 8. | My PC/laptop displays a status of "Limited Or No Connectivity" for the network connection. How do I resolve this? | | | This message can result from any of several different technical glitches or configuration problems. Follow these steps to resolve Limited Or No Connectivity errors in Windows.
Determine whether your network access is functioning properly (that you can reach local network resources and the Internet). If you are using a broadband Internet and Windows XP Service Pack 2, this message is often a false error report. See Microsoft Knowledge Base article 892896 for details on how to work around this error appropriately.
If your network access is non-functional continue to the following steps.
# If your computer connects to the network through a broadband router , resetting (powering off and on) the router may resolve the issue. If not using a broadband router, or if resetting your router only temporarily resolves the issue and the error message re-appears later, continue to the following steps.
# If connecting to your network using Wi-Fi and using wireless security, your WEP or other security key may not be set properly. Check the wireless security configuration on your computer's network adapter and update if it necessary.
# If connecting to your network using an Ethernet cable, your cable may have failed. Temporarily replace your network cable with a new one to determine whether this resolves the issue.
# If using a broadband router and DHCP on your network, check your computer's IP address to verify it is valid and not a private address that starts with 169.254. An invalid address of the form 169.254.x.x signifies your computer's inability to obtain a usable IP address from your router.
To resolve DHCP configuration problems, proceed to the following steps.
# Reboot your computer, router (if present) and broadband modem together, then re-test your connection.
# If your connection remains non-functional, run the Windows Network Repair utility on your computer.
# If your connection remains non-functional, update your router settings to change from dynamic to static IP address configuration, and set an IP address on the computer appropriately.
# If your connection remains non-functional, unplug your router and connect the computer directly to your broadband modem. If this configuration is functional, contact the manufacturer of your router for additional support.
# If your computer is connecting to your network directly through a broadband modem, or if your Internet access remains non-functional after following the instructions above, contact your Internet provider for support. | | 9. | What Is a VPN (Virtual Private Network)? | | | A VPN supplies network connectivity over a possibly long physical distance. In this respect, a VPN is a form of Wide Area Network (WAN). VPNs enable file sharing, video conferencing and similar network services.
A key feature of a VPN is its ability to work over both private networks as well as public networks like the Internet. Using a method called tunneling, a VPN use the same hardware infrastructure as existing Internet or intranet links. VPN technologies includes various security mechanisms to protect the virtual, private connections.
Specifically, a VPN supports at least three different modes of use:
* Internet remote access client connections
* LAN-to-LAN internetworking
* Controlled access within an intranet
Internet VPNs for Remote Access
In recent years, many organizations have increased the mobility of their workers by allowing more employees to telecommute. Employees also continue to travel and face a growing need to stay connected to their company networks.
A VPN can be set up to support remote, protected access to the corporate home offices over the Internet. An Internet VPN solution uses a client/server design works as follows:
1. A remote host (client) wanting to log into the company network first connects to any public Internet Service Provider (ISP).
2. Next, the host initiates a VPN connection to the company VPN server. This connection is made via a VPN client installed on the remote host.
3. Once the connection has been established, the remote client can communicate with the internal company systems over the Internet just as if it were a local host.
Before VPNs, remote workers accessed company networks over private leased lines or through dialup remote access servers. While VPN clients and servers require installation of hardware and software, an Internet VPN is a superior solution in many situations.
VPNs for Internetworking
Besides using virtual private networks for remote access, a VPN can also bridge two networks together. In this mode of operation, an entire remote network (rather than just a single remote client) can join to a different company network to form an extended intranet. This solution uses a VPN server to VPN server connection.
Intranet / Local Network VPNs
Internal networks may also utilize VPN technology to implement controlled access to individual subnets within a private network. In this mode of operation, VPN clients connect to a VPN server that acts as the network gateway.
This type of VPN use does not involve an Internet Service Provider (ISP) or public network cabling. However, it allows the security benefits of VPN to be deployed inside an organization. This approach has become especially popular as a way for businesses to protect their WiFi local networks. | 10.
