Network / Sharing :: How To Protect Computer From Another One Attached To LAN
Jun 7, 2014
I fix computers when they get a virus etc. and want to be able to connect their computers to my home network while at the same time ring fencing their computer so that they can only access the internet (for updates and virus definitions).
I want to be able to prevent their machine from seeing and interacting with my computer and other "trusted" machines and devices on my network and I want all of my machines (Windows 8.1 and Windows 7) from having their media sharing services and shared folders etc. popping up in my machines.
I understand that I can setup VLAN's for this purpose but sadly my router Netgear DG834GT does not have VLANS.

My ISP provides service only via 802.11. I use laptop A most of the time. The captive portal for the service provider only allows one login per account at a time. The policy is intended to prevent multiple people sharing one account. It's just me, I'm the only user, but very occasionally I'd like to have a 2nd laptop access the internet simultaneously. No abuse, just the simple convenience of not having to logout from A if I need to use B for 30 seconds.
What I want to set up seems simple and it probably is:
WiFi Internet <---> Laptop A <---> ethernet cable <---> Laptop B
Such that Laptop B can share A's active WiFi connection without having to request its own unique address from the ISP.
At present, Laptop A has its network interfaces set up so:
- WiFi is connected, active, functional. Selected the "Yes turn on sharing and connect to devices" in sidebar.
- Under the wired network properties IP Version 4, I manually set addresses to be
IP 192.168.10.1
Subnet 255.255.255.0
Gateway 0.0.0.0
Laptop B has only a wired network, set to
IP 192.168.10.2
Subnet 255.255.255.0
Gateway 192.168.10.1
A & B can connect directly to each other, share folders, etc.
What do I need to do in order to get laptop B to transparently use A's WiFi connection? My guess is that A needs to be set up to do some routing between the internet side and the 192.168.10 subnet, and B needs to be set up to look to A as its "ISP" ... but I don't know where to begin.

It was working earlier but couple of hours later when I booted up my Windows 8 laptop.. There was a red x on the network I was trying to connect to and a message saying my computer settings not matching.
I looked it up on youtube and I tried selecting "No authentication" and for encryption type I chose "None". But still didn't work.
Sometimes it would say limited first then when I try to reconnect the message above will appear.

I have a local network at home with 1 router, 5-6 computers and a few gadgets connected through WiFi.
I have a problem with one of the computers with Windows 8.1, let's call it Computer A. When I boot it, it is connectable from the other computers using its local IP address. But after a few hours it usually disappears from the network, and I'm only able to connect to it using the router's external IP and port forwarding.
By "disappears from the network", I mean that it's still connected to the router and to the internet, but none of the other units on the network is able to connect to it in any way.
Computer A can always connect to the the other computers on the network and to the internet.
The problem is solved if I reboot Computer A, so at the moment I have a scheduled task to reboot it every night. Unfortunately, sometimes it disappears from the local network after only a few hours after boot.
Turning the firewall off on Computer A doesn't work.
Below is the result of ipconfig /all on Computer A:
Code:
C:WINDOWSsystem32>ipconfig /allWindows IP Configuration
Host Name . . . . . . . . . . . . : bjarte-media2 Primary Dns Suffix . . . . . . . :
Node Type . . . . . . . . . . . . : Hybrid IP Routing Enabled. . . . . . . . : No
WINS Proxy Enabled. . . . . . . . : No DNS Suffix Search List. . . . . . : getinternet.noWireless LAN adapter Local Area Connection* 2: Media State . . . . . . . . . . . : Media disconnected

Would it be possible to hide the 'Network Locations' in the 'My Computer' section in 8.1?

Windows 8.1x64 clean install from dvd. I have a private network configured as a Workgroup consisting of a W2000 photocopy machine,XP desktop, W7 desktop and laptop and now a Windows 8.1 desktop. During the initial installation I have files on the Windows 7 desktop I need so from Windows Explorer I clicked on the Windows 7 computer to gain access to the password shared folders and their files. I entered the User and Password info and clicked the "stay connnected" as I expected to reboot several times during this computers installation.
Everything worked just great UNTIL I no longer wanted the connection to the Windows 7 computer. On XP and even Windows 7 it was trivial to Disconnect a computer that I had established a share with.
However, on Windows 8.1 I cannot figure out how to do it. How do I disconnect the share with the Windows 7 computer?
This may seem trivial but I cannot figure it out. Obviously I can disconnect from the W7 computer but that computer is shared with others as well. And then the other computers would have to re-establish their shares. And, that would just be a work around.

I have an aunt who runs a business who wants to be able to let the computer run over night at her business and let me access it remotely to do the usual disk cleanup, defrag, virus scans and backups. Currently I have to go on Sundays to do all this and it is just a pain to sit there and wait for the task to complete. I did have some of these automated but some how under the computer illiterate they always get messed up.
Is there a piece of software (preferably free) that will let me access her machine to do all this? It doesn't matter if I need her on the other end to grant me permission to access the machine but I would rather do this from home during the night then do all this on a Sunday.

It just occurred to me that I don't know how this works.
When I share files, are they transferred via my router, the internet, directly computer to computer, black magic?

I have a USB printer connected to an 8.1 system. This printer is shared. I don't like keeping the computer on 24/7 so I set it to sleep.
Is there a way to send a wake command to the system when I want to print? WOL is working on the system. I noticed Homegroup has the option to wake the computer to view shares (and that does work).
If I can't wake the computer before a print job, what is the best practice to conserve energy on a system that is primary used as a print server?

I have two Windows 8 computers. On one of them (which says "private network"), I easily created a homegroup. On the other (which also says "private network"), I am unable to join the homegroup. Whenever I connect to the network, it searches and says "There is no homegroup on this network" and displays "Create Homegroup" in the Network and Sharing Center. However, when I attempt to create the homegroup, it says "Can't create a homegroup on this computer". If I leave the homegroup on the working computer, it still says "Create Homegroup" in the Network and Sharing Center and I am still unable to create the homegroup. Microsoft has worked on this for five hours and is unable to find a solution.

We are upgrading our office to windows 8, but 1 computer is hardly ever used and is running XP. It will stay with XP, and should not be allowed to go online for security reasons.
All computers are networked, and share printers thru a netgear vpn router. Of cause they all can go online. Question: How can I prevent the XP computer from going online?
I opened the netgear router settings ( http://192.168.0.1 ), but can not find any setting blocking a computer from going on line.

My neighborhood shares a wi-fi connection. When some neighbors see my computer is connected to the network, they assume I'm awake and accepting visitors. I want to prevent my computer from appearing when you click on Network and all PC's and connected devices appear.
I'm running Windows 8. I opened a command prompt and entered net config server /hidden:yes and "the command was completed successfully". I then restarted my computer and logged onto the network, however my PC is still visible along with the other computers and devices connected to the network.
What additional steps must I take to accomplish this task?

I have to reconnect my Win 8.1 computer each time it's started,my Win 7 computers do not have this problem. Also my Canon G16 WiFi camera can connect to all my Win 7 systems but not to my Windows 8.1 the camera is not found. Windows 8.1 has been a real bummer. Just glad I still have other computers running Win7.

Currently I have a home network and need to do some rewiring but wanted to know if a software solution exists.
Right now I have the following setup
Code: +------+ +--------------+ +--------------------+ |Modem|----------->|Wi-Fi Router |+-------->|Desktop Computer| +------+ +--------------+ +--------------------+ + + | | | | +------+ | +-------------->|Server| v +------+ +----------------+ |Laptop Computer| (wifi atapter is OFF) +----------------+ + | v +---------------+ |Network Storage| (security storage computer NAS200) +---------------+
My laptop computer is the only computer has 2 NIC and thus I have set it up so that no other computers on my network can reach the network storage. I will be changing how things are wired together so that the network storage will now be connected through the Wi-Fi router, however I want to maintain the security of not allowing other computers on my network from reaching the network storage.
Is there a way that I can do this? Can I put the network storage computer on a different workgroup from the other computers? Can I have my laptop see 2 work groups so that it can see both the network storage and my home (unrestricted) LAN?
I am running windows 8 (not 8.1) x64 on all my computers. My router is a Linsys E4200.

Can a group of computers (20-25 Units), all running Windows 8 Single Language, share files, printers and an internet connection via a LAN? I need to make sure that the OS I will be getting with my new machines will be able to do this. The cheapest license I could get for this is the Windows 8 SL? Is if up for the job? I also have 2 switches, a router and my internet source is from a cable modem.

Whenever I boot up my computer, I always have to go and connect to the internet. It doesn't automatically connect to the internet. I don't want to do this anymore. I tried clicking "Connect Automatically," but that didn't solve the problem. I also tried troubleshooting. It found some problems, and it was the problems were fixed but it still doesn't work.

I have a Samsung Series 9 13in laptop running windows 8, and I'm attempting to stream video to my xbox 360 (it's one of the new, "slim" ones). I've read you need your homegroup set up in order to facilitate this, but I'm having nothing but trouble with it.
When I try to change any settings on the homegroup, most of the settings are greyed out, and the ones a can change reset as soon as I do it.
Screenshot is here: [URL] ....
How do I enable these settings? Any tips for streaming from Windows 8 to xbox?

I've been looking for a PC that I can use to simply connect to another computer on the LAN with remote desktop. Nothing else at all, just remote desktop.
I found this one, and I was wondering if it would be any good: HP 110-101 Desktop PC and 20? Monitor Bundle | Officeworks

I'm running Windows 8, (unfortunately), & I can't access certain files even though I'm the only one who uses this laptop & I'm also the Administrator. I tried numerous times to allow file sharing & change what I thought I should, but I kept getting red-lettered statements saying that I'm not allowed to make such changes.what steps to take so I can get to the files I need. There's no reason why I should be denied access to do anything when it's my own computer!

For some oddball reason, my computer will only recognize an ethernet connection. It wont even give me the chance to connect to a wireless network. It doesn't even give me the option.

When I go to advanced system settings and choose Home instead of business, when I save and restart it is still on Business network. I have windows 8 pro 64 bit on a HP pavilion elite 8 gb ram i6 1tb drive. I have made sure that the services below are running as well as set to Auto.
o Computer Browser
o DHCP Client
o DNS Client
o Network Connections
o Network Location Awareness
o Remote Procedure Call (RPC)
o Server
o TCP/IP Netbios helper
o Workstation
Also, I have recently "refreshed" my computer which I thought had fixed it. It actually fixed the "turn file sharing" not saving issue I was having, now this.

My computer hard rive recently crashed and was sent off to manufacturer to be supposedly fixed. Once I got it back my internet connection was spotty. Internet explorer would often stop working. It got to a point that I could not connect tonetworks, I tried multiple networks. This occurred a week before I left the country and didn't have much time to look into it.
I am connecting to a network and only getting "limited connectivity". My iPhone and iPad are able to connect. I've spent a few hours playing with it and googling. I get the message "one or more network protocols are missing on this computer". When I check the network connections it says IPv4 Connectivity: No Internet Access. IPv6 Connectivity: No Internet Access.
I have Windows 8.

Many times in the past when I buy a new computer, I backup the hard drive of the one I am getting rid of to an external drive, I then try to access from the new computer and I get permission errors.
I'm about to replace my computer yet again and I was wondering the best way to do this to avoid any issues.
This is the first time I am doing it between 2 Windows 8.1 computers and wondering since I login to both with my microsoft account, if the issues will still be there.
Also, free backup software would work too. I usually use free version of Macrium but it has become a lot more limited.

I have run into some networking problems and I think I have narrowed it down to the homegroup provider.
I have 4 windows 8 pro x64 computers connected to a router. Up until now, I have been able to disable the homegroup provider service because I don't want to use the homegroup and don't want to see it in my file explorer. I have been able to connect to all the shared computer drives up until I tried to disable the homegroup provider on my netbook. When I did this I lost the ability to connect to other shared computers. I re-enabled the provider, however I still cannot see drives on other computers. I can now see my netbook on the other shared computers.

I have an Asus computer running windows 8. When I open the network connections I cant see the list of available networks. I see my own connection to the internet which is named Network but that is all I see. when I check it on my laptop also running windows 8 I see a full list of available networks. Is there a setting in windows that will allow me to see this or is something blocking the list from being displayed.

I had to restart a computer on our office network which uses Windows XP on Wednesday, September 17, 2014. Now I cannot access a file on a computer which uses Windows 8 unless I tell the Windows 8 computer to let EVERYONE access the file - which I don't want to do. A computer using Windows Vista on the same network has had no problems. I've created a new username on the Windows 8 computer and given the problem computer that name but still no access. I've enabled read/write file sharing and given the problem computer full access permissions but still can't get in. I removed all Microsoft updates that had been installed four days before the problem occurred on the Windows 8 computer and recovered the Windows XP system to the day before the problem occurred - still can't get in.
