I am having the same problem with adding a new laptop computer to my network. I am not running antivirus and have turned off all fire walls

I get the error "Check the spelling of the name, make sure the computer is turned on and connected to the network."

Hi, Thank you for posting. Firstly, to identify the issue clear and help provide more proper suggestions, please let us know the following: 1. Are the computers in a domain or a workgroup environment? How do you setup the network? 2.If it occurs when trying to join the computer to a domain, please collect the file C:\Windows\Debug\netsetup.log. 3.What do you mean by adding a new laptop computer to my network, adding the laptop to domain or just accessing the laptop with other computers? 4. Please help capture a screenshot on the "Check the spelling of the name, make sure the computer is turned on and connected to the network.". Capture a screenshot ============== 1) Press the Print Screen key (PrtScn) on your keyboard. 2) Click the "Start" menu, type "mspaint" in the Search Bar and Press Enter. 3) In the Paint program, click the "Edit" menu, click "Paste", click the "File" menu, and click "Save". 4) The "Save As" dialogue box will appear. Type a file name in the "File name:" box, for example: "screenshot". 5) Make sure "JPEG (*.JPG;*.JPEG;*.JPE;*.JFIF)" is selected in the "Save as type" box, click Desktop on the left pane and then click "Save". Please use Windows Live SkyDrive (http://www.skydrive.live.com/) to upload the file and share its URL with us. At this time, we can also perform the following basic checks to narrow down the issue: 1. Please ping the laptop with other computers in the network via both IP Address and computer name. 2. Check if you can access the laptop with other computers via both \\computer name and XXX.XXX.XXX.XXX\. 3. Check if the laptop get the proper network configurations (IP Address, subnet mask, DNS, etc.). You can also run ipconfig /all on the laptop and other computer which works well and attach the reports here, we will help you check them. Hope this helps. Thanks. Nicholas Li - MSFT
