Checking your IP Address in Windows is easy and pretty much the same process for every version. The easiest way to get your IP address is from a command prompt. To get to a command prompt simply click on Start and then Run and type in cmd and press Enter. If you don’t have a Run option then you can type it in the search box like you see in Vista and Windows 7. Once you get the command prompt window open simply type in ipconfig and press Enter.
If you have more than one network adapter such as a wireless adapter then you will have more than one entry. Look for the entry that goes with the connection you are using. If you plug in using an Ethernet cable then look for Ethernet adapter Local Area Connection. Then look for the line that says IP address. For newer versions of windows that support IP 4 and 6 it may list both. You want the line for IPv4. In the example the IP address is 192.168.1.2.
This can be helpful in troubleshooting other network connectivity problems as well.
For Windows 7 and up you can disable the Link-Layer Topology Discovery Responder for your network adapter. The Link-Layer Topology Discovery Responder allows your computer to be discovered and located on the network. To do this open up the properties of your network adapter by going to Control Panel and then Network and Sharing Center and clicking on Change adapter settings. Then right click on your Local Area Connection or wireless connection and choose Properties. Then uncheck the box next to Link-Layer Topology Discovery Responder.
Another option is to turn off network discovery which controls whether your computer can find other computers on the network and if other computers can find your computer. Keep in mind that turning this off will make it so you can see other computer on the network as well. To do this click on Change advanced sharing settings and then go to either Home or Work, Public or Domain depending on how you originally setup your connection and turn off network discovery.
There are a couple ways you can go about finding an IP address of a website. One simple way is to ping the website name itself. To do so open a command prompt and type in ping www.websitename.com and press enter. It will then show you the IP address of the site.
Another way is to use a WHOIS website to find out the IP address and other information about a particular website.
That error means that both of your computers are using the same IP address. An IP address designates your location on the network. Since you are sharing an internet connection you are technically on a network. 2 computers cannot have the same IP address on the same network.
If you are using a DSL/Cable router it should be assigning the IP addresses to your computer when you boot it up. It may be the same address as the last time you booted or it could be different. The router is supposed to know which IP addresses are in use so it doesn't duplicate them and give the same one to another computer. In your case either your router is having a problem or one of your computers has a static IP address and the router is trying to give that same address to your other computer. A static is an IP address that is manually assigned to the computer and never changes unless you change it manually.
On both computers make sure you don't have static IP addresses. Go to Control Panel and then Network and Sharing Center. Then click on Change adapter settings and right click your Ethernet or wireless connection and choose Properties. Double click Internet Protocol Version 4 (TCP/IP) and make sure Obtain an IP address automatically and Obtain DNS server address automatically are checked. If they are checked already then its most likely your router is having problems with its DHCP which is the service that assigns IP addresses to your computers.
Here a couple of methods/links that may get you started doing what you want to do. This is assuming you already have your list of users you want to add.
You can use the Addusers.exe tool from Microsoft along with a comma delimited text file to add multiple users.
Another method you can try is the Microsoft CSVDE.exe utility
There are a few ways for you to turn your computer on remotely. If you want to do this on a networked computer on the same network you can use Wake On LAN assuming your computer's network card supports it.
If you want to do this from a remote location then it can be done over the internet a few ways. You can use the Wake On LAN method or Wake On Ring method which is similar except it uses a modem instead of your network card. You most likely will have to have a static IP address for the location where the computer you want to turn on is located as well as a method of translating the public static IP address to the local internal address. Check out this link for more details.
There are also other hardware devices that will do the same thing as WOL but with more advanced features.
Is this the only computer you have connected to the internet? If so you should connect to the wireless router using a network cable first to make sure you can get online. You may also need to get into the router's settings to make sure it is setup correctly for your system. After it is plugged in you should unplug your modem and router. Then plug in the modem first and wait for all the lights to come on. Then plug in the router and wait for all the lights to come on. Finally reboot your computer. The modem gets its configuration from your ISP, the router gets its configuration from the modem and the computer gets its configuration from the router.
If you can get online while plugged in with a cable then make sure the wireless settings are correct on the router. Make a note of the router name (SSID) and try and find it with your wireless connection to make sure it is available. Then try to connect to it if you can see it. Check out this page for more details.
Are you sure your wireless connection is working? Even though you are connected to the router your computer may not be getting the proper IP settings from the router. If you right click the wireless connection in the taskbar by the clock do and select View available wireless networks do you see your router in the list?
If you are making a connection to the router you should next check your IP settings. Go to Start, Run and type in cmd and click Ok. Then type in ipconfig /all and make sure there is a number such as 192.168.0.100 for the IP Address section. If its all zeros or a number that starts with 169.254.x.x then you are not getting the IP information from your router.
If you are getting a correct IP address then you should check your and then click on Setup. Follow the prompts and check the right information. You most likely do not have any proxy settings to fill in so have Internet Explorer do it automatically.
An additional test to see if you have internet connectivity is to go to Start, Run and type in cmd and click Ok again. Then type in ping www.google.com and see if you get a reply. If so then you have connectivity to the internet and its most likely a browser or firewall setting. If not then you do not have connectivity and may want to contact your internet provider.
I would first check to make sure they are in the same workgroup by going to the system properties of both and then look at the Computer Name section. Plus make sure you have something shared on the computer so the share will show up when you browse for it.
Next you should check the IP configuration by opening a command prompt and typing in ipconfig /all and compare the results for the IP addresses and subnet masks. The IP addresses should be similar except for the last group of numbers such as 192.168.0.2 and 192.168.0.3. The subnet masks should be the same. Once you get both IP addresses you can ping one from the other. For example on the 192.168.0.2 computer type in ping 192.168.0.3 from the command prompt and see if you get a reply.
If you have any firewall software such as Norton Internet Security there is a good chance that it is blocking the connection. Check the settings or disable it to test it. You might also disable the Windows firewall temporarily to see if that's causing the problem.
If everything checks out, do a search by computer name or IP address from Windows Explorer. From the address bar type in either the computer name or IP address and see if it comes up in a search. It should be in this format: \\computername or \\IP address.
It will depend on if it's an actual network printer or just a shared printer. You will need to find this out first since both processes are different.
If it's a networked printer with an IP address then you can add it as a local printer and add the IP address as a printer port. Then when it finds the printer you simply direct it to the drivers that you have on a CD, your hard drive or a network share.
If it's a shared printer on another computer you can browse the network for the computer that it's on and then double click the shared printer to install it. It will copy the drivers to your computer automatically and install the printer. If it's a different version of Windows you may need to provide the drivers manually depending on the version.
You need to make sure that all of your computers are on the same subnet if you don't have a router. I would also make sure you have Client for Microsoft Networks installed as well as File and Printer Sharing for Microsoft Networks installed under your network connections properties so you can access shared resources.
Check the IP address on each system using ipconfig /all and compare the results of each one to make sure they have the similar IP addresses and identical subnet masks and gateway addresses.
If you are using DHCP make sure you have a DHCP server on the network giving out IP addresses. You can check this under the settings of your network connection as well by double clicking Internet Protocol (TCP/IP).
Also make sure you have something shared with the appropriate permissions so you have something to browse for and connect to on the network.
Depending on how you have your network setup you may need to adjust the user permissions or make accounts for the other users so they are able to access your shares.
The WEP key is a password that secures your wireless internet connection from people connecting to it that you don't want to use it. Once you connect to it the first time and put in the key then Windows will store the key so you don't have to enter it each time.
If you have a wireless router you can log into it assuming you know its IP address and password. If somebody else set this up then you may need to ask them. You can connect a network cable to the router to access it directly but will know the login information to do so.
If you are the only one using the router you can reset it back to the default configuration and reconfigure it from scratch. There should be a reset button on the back or on the bottom. You can look online and get the default password for the router to login and start the setup.
If you don't know the make and model of your network card then you are going to have to open the case and take out the card and see if it’s written on the card itself. Then go to the manufacturer's website and download a driver for your version of Windows. If it’s a built in network card then it will be harder since you will have to find the motherboard make and model and do the same thing. Some motherboards mark this information on them and others make it harder to find. Just make sure you unplug the computer from the wall first.
If it’s a name brand computer like a Dell or HP then you can usually find hardware drivers by finding the model number or service tag number like in the case with Dells and then going to their website to get a listing of drivers. Since you can’t get online you will have to do this from another computer and copy the drivers to a CD or flash drive.
It's unlikely that a virus is affecting the physical port itself but may be doing something to block access to the port. Since you are getting an APIPA IP address (169) then your computer is not able to talk to your DHCP device. I would boot into Safe Mode with networking and see if you can get a connection/IP address that way since many virus and spyware programs don't start up in Safe Mode.
If you know the IP address and subnet mask of your network or if you have another computer connected to check the settings then you can assign a static IP address and see if you can communicate that way.
You can also go into Device Manager and remove the network card, reboot and have Windows find it and reinstall it to see if that helps. Finding and installing a new driver may be helpful as well.
Another way to check the port is to check the link light on the other end of the connection. If a connection is being made and packets are being send then you should get the link lights on the other end of the connection such as your router or switch to light up even if your computer doesn't have an IP address. If the link light on the other end is not lighting up then you may have a faulty Ethernet card itself.
I would go into Device Manager properties and then find your network card and right click on it and choose properties. Then go to the Power Management tab and uncheck the box that says Allow the computer to turn off this device to save power.
I would also try to update the driver for your Realtek card. You can find the model in Device Manager and then go to the manufactures website and download the latest driver.
You should also check the network cable to make sure it has a good connection to the port. It may be a good idea to replace it in case it is having connection problems that may be causing the network card to disable itself.
Do you have a broadband router or do you plug in directly to the modem? Your computer most likely uses DHCP to get its IP address from the router and then the router gets it IP information from the modem. If you are not using a router then the computer gets its IP information directly from the modem.
Your computer may be having a problem getting its IP information from the router or modem. If you are using a router try going directly into the modem and bypass the router. Then see if you have the same problem after a couple of reboots. If so then your router may have a problem giving your computer the IP information it needs to connect to the internet.
If you are not using a router then your modem may not be giving the computer the proper information. When it does not connect you should check the IP information and make sure you are getting an IP address.
If the IP address begins with 169.254.x.x then that is the Windows autoconfig IP address that is uses when it can’t get one from a DHCP device. If the IP address is all zeros or uses the autoconfig IP then you can try to renew your IP address to see if that makes a difference.
There is also a chance your computer could be having issues obtaining an IP address but I would check the router and modem first.
