2 Nics In Windows 7 - Deleted Route Automatically Reappears
Jun 30, 2011
I have 2 NICs in my Windows 7 PC at work.NIC #1 connects to our private network and is also how I connect to the internet. NIC #2 connects to our customer's network and does not allow internet connectivity for me.When I first boot up my Windows 7 machine I get the following info in route print:Despite the fact that I have a persistent route with metric 1 to send my internet traffic to the 172 subnet, the internet requests go to the 10 subnet. I am guessing that is because the non-persistent route to the 10 subnet has a metric of 20 vs. the 21 for the 172 subnet. I delete the route 0.0.0.0 mask 0.0.0.0 10.242.1.254 and I am able to connect to the internet again.HOWEVER, after something like 4-6 hours, (without rebooting) the bad route automatically reappears in my route table! I become aware of it because I suddenly have connectivity problems. There are no entries in the Windows Logs that seem to be related (i.e., no DHCP renewal requests.) so I do not know how or why it reappears.

I have the setup as following on my PC:
[code]...
I use the fibre internet for almost all internet activities since the speed is fast.However, when I do school's stuff, I need to VNC to my lab's server. Hence I need to connect to school internet point. External IP cannot directly connects to my school's server.Therefore, I would need to force Windows (or VNC) to use the connection of the Wireless Ethernet card when I VNC to my lab's server. But I want to use my fibre for all other internet activities.

I want to route traffic from nic 2(192.168.2.1) to nic 1(192.168.1.1). In lame terms route the traffic from 192.168.2.10(gateway 192.168.2.1) to 192.168.135(192.168.1.1). I know how to use the route command in CMD. So how would I get the traffic from 192.168.2.10 to 192.168.1.135? I'm just not sure how I would do that with the route command. I've tried
Code:
route -p add 192.168.1.135 mask 255.255.255.0 192.168.1.1 IF 12
Also tried like 5 different ways The IF 12 is my NIC 2.

The situation is I have a windows 2008 server with two nics, connected to two routers. The routers are connected together as well. This diagram might explain further:[url]....
Each router effectively defines a completely different network. The server nic connected to the internet facing router is configured with minimal properties (no ip6, no file sharing, no netBIOS over tcp etc), the nic connected to the internal router has mostly default properties. Both nics have static ip addresses. Both networks define a subnet of 255.255.255.0. The nics are not bridged in the server and it is not acting as a router or anything network related.
The problem is I cannot access the server when both nics are enabled. If I disable the nic for the internet facing router, then everything is fine. If I establish a connection to the server such as through remote desktop, then re-enable the nic it still works but I can't ping or make new connections.

I am running Windows 7 and I use a ZyXEL ZyAIR G-220 Wireless USB adapter for internet. I had a virus called something like Cloud AV 2012 so I used Malware Bytes to remove it and it worked just fine. However, now the internet does not seem to work (there's that yellow triangle with the exclamation point) and when I try to run diagnostics, the message "Windows could not automatically detect this network's proxy settings" comes up. So far, I've tried rebooting, disabling proxies in all of my browsers, and running scans, And I also cannot system restore, because apparently windows security was turned off and there are no restore points

I'm on windows 7 btw.When I diagnose the problem it says: Windows could not automatically detect this networks proxy settings I'm connected to the internet via cable on my laptop. Yes I'm using a router. The other computers connected to the router can connect to the internet but mine can't. It also says "unidentified network - no internet access" when I click on the computer icon in the bottom right corner of the screen. until I downloaded from a music site which gave me the virus I think. Now, I'm not certain if the virus is removed or not. I tried system restore point but it won't even let me restore my computer anymore for some reason, maybe because of the virus.

the cursor on my laptop started jumping all over on its own accord and I am struggling to gain control of it and various programs & windows are opening of their own. I assumed I had some form of Malware (I know very little about computers) so ran various removal scans and a few things were picked up but it continues to do this. My brother brought his laptop round so I could at least use the internet and after 5 mins of being connected to my internet his laptop started to do exactly the same cursor going all over and programs opening - his laptop was perfectly fine until he connected to my internet. Once he took his laptop back home on his own network it was working perfectly normal again.

I'm using my old laptop now. On my regular laptop, my internet icon has the yellow triangle and when I trouble shoot it, the message says "Windows could not automatically detect this network's proxy settings".Recently I noticed my computer was heating faster (and hotter) than usual so I ran a search again and it said no threats were found. I have ran the search twice since then and still nothing. I was advised to use ccleaner,malwarebytes, and Super Anti-Spyware. It removed one other threat but the problem was still there. I then started using combofix, but I did not like the look of it so I stopped that scan. It seemed a little sketchy. As of this morning, I'm having the internet problem. My old laptop (the one I'm on now) and my girlfriend's laptop work fine. I connected it with the Ethernet cord and that didn't change anything. I have Windows 7. It's on a 2010 Samsung (I'm not very tech savvy so I'm not sure about all the other details).

The other day i was on my mums laptop (ASUS X5DIJ) at her house all working fine the battery died so i plugged it in and started it up again however the charger cant have been fully connected and once back in windows the battery died again on the next boot i noticed windows said it had found the system CMOS/real time clock and had installed drivers for it. checked the driver details it says no driver files are required just like it should ever since then it connects to the network but will not connect to the internet at her house or at mine through wireless and ethernet cable although all other computers work fine windows troubleshooter says "Windows could not automatically detect this networks proxy settings"
I've tried
resetting routers and laptop = no change
netsh winsock reset and netsh int ipv4 reset = no change
ipconfig /flushdns = no change
ipconfig /registerdns = no change

1 computer (Computer A) has 2 NIC cards. 1 NIC card is on the LAN which connects out to the internet.1 NIC card is connected to another computer (Computer B) via crossover cable.
Assume Computer A NIC #1 IP:
1.1.1.2
Assume Computer A NIC #2 IP:
1.1.1.3
[code]...
Computer A and B can ping each other on their connected NICs. But Computer B cannot ping Computer A's network/LAN facing NIC card.Also Computer B cannot connect to the network. I cannot use Microsoft ICS due to company policy. I think I can use the route command and have a persistent route that would allow computer B to connect to the company's network. Also the bridge command also seems disabled (even when I select both connections at once).How should I configure the route command? Should I have a default route?I assume from Computer B the default route would something like this:route add 0.0.0.0 mask 0.0.0.0 1.1.1.3Does the network connection from Computer A to B need a default gateway?Are there any extra commands aside from the default route which would allow full connectivity? I'm trying now just to be able ping Computer A interface #1 to/from Computer B. But no luck. I want to statically configure Computer B with the same DNS settings, and bring it up on the domain.

I have a networked PC with 2 NICs.One is connected to our business network, with a static IP address (10.38.75.xx) the other NIC (10.42.10.xx) is connected to a Controller machine.The business side of things works fine - network access & internet access works well.The intent with this PC is for a vendor to be able to RDP it (which he can) then open a browser and use the Controller's IP address (10.42.10.33) to access and control the connected machine.I am an administrator - logged in as myself, and trying to browse to this IP address, the page tries to load forever. It never times out or displays an error - just continues trying to load.At first, the vendor that was accessing this machine, when logged in as himself, COULD get the web page to open up at that IP - but he wasn't authorized to install an activeX program that needed to be installed. Logged in as myself, I couldn't get to the point where it asked to install the program.
Because I couldn't figure out how to fix this, I just set him as a local administrator as a short term fix - now he can't access the web page either. I've tried setting him back (removing his adminstrator privileges) - but now neither of us are able to access this page.

I have a quick question to ask regarding bridging two NIC/LAN ports on my home server to two LAN ports on a single gigabit router. Is this possible? Will the router have any trouble determining IP addresses? If so, is a certain router required for this to work that I am unaware of? I'm run a google search for any info on this subject but this particular question doesn't seem to have been asked that I'm able to find.
I'm essentially looking to increase any bandwidth throughput if possible for content streaming on my home network.

I have 2 nics in my win7 system, NIC 1 connect to leased line and NIC2 is connected to organization LAN for internet. Both the ip add are in same subnet. when both the cables are plugged in to nics, leased line link connected to nic1 goes down. It wouldn't come up untill the cable from nic 2 is plugged out.Basically i wish to be connected to both the networks simultaneously.

So i have a server with an internet nic and lan nic. The internet nic gets its IP from the router 192.168.1.7 the lan nic uses DHCP for the network and has 172.16.1.1. I just turned on the ftp service and it works fine in the lan side but cant reach it from the ISP side. I use a dynamic dns host which is monitoring my internet ip and is correct.

Ok so even though this isn't really needed, it's for a 10 user office I have two tower servers with dual nics but not the same brand (just bought a cheapy gigabit startech) to go with intel on board nic. Also my switch is also gigabit which is a trendnet teg-s24dg which does not support link aggregration.
But since I have two nics and both servers are running win2008 enterprise I want to use the other nics for throughput if possible. So to give an idea servers are doing DC/AD and fileserver DFS rep. If I turn one off the other picks up and network still functions (there is a small lag since dns has to pick up that other is not responding. So far the best I can think I can do with the extra nic is add ip's to second nics and add to dns and round robin or install NLB role to for two server cluster.
I can't really team them since they are two different brands, so what would you do or do you suggest I can do with them. Also I have a T1 and dsl going into a dual wan firewall dsl is not being used for anything. (might use it for a seperate wifi network if people need it.

I know enough to be dangerous when it comes to networking, but this one has me baffled. I'm running a win 7 pc with dual nics.
I need to have 1 nic connected to a vpn and the other to be restricted to intranet access only. I can't for the life of me figure out how to accomplish this.
Once I connect 1 nic to the VPN i'm no longer visible to my lan, even if the 2nd nic is connected.

I am using a proxy server with 2 NICs for sharing internet connection to my 100 desktop users in my office. NIC 1 is connected to my dsl modem and NIC 2 is connected to a main switch and further to more. But now i want to setup a wifi network for laptop users. I have enabled ICS on NIC 1 and NIC 2 has acquired it ip automatically (192.168.0.1) so the gateway for my desktop users is (192.168.0.1). But i want to use a new gateway. For this i have installed NIC 3 but it is not acquiring the ip automatically. My Proxy server configuration is: MS Server 2003 ENT edition.

Following is my Hardware
Router: 3Com OfficeConnect ADSL Wireless 11G firewall
Laptop: Lenovo 3000 N200 - Vista
Built in NIC: Intel PRO/Wireless 3945BG
USB NIC: Linksys Compact Wireless G
I am trying to connect my Laptop to Media Player HDD connected via Ethernet to Router. I want to channel traffic to/fro HDD separately from that of internet to/fro laptop (to make it faster - my assumption)
I have successfully done this by using the router as a switch when I had a cable modem. But now I have an ADSL connection to internet and my internet gets kicked off while I connect these using VLAN.
What I want is best possible configuration of my hardware to access internet and play/transfer media files on my laptop

I have a PC on a crowded network that cannot handle much more bandwidth usage.I am now going to have a tons of transferring to do offsite so I added a second internet line just to deal with the influx of file transfers.I tried a dual WAN setup on my router and the performance was not improved (if it was nobody noticed it) so I said forget that idea, I only need to do these massive transfers from 1 PC so I will just add a second NIC to the machine so that the 1st NIC can maintain local network functionality and the 2nd NIC will be just for internet traffic (sending files up/down to offsite location) Essentially I just need NIC1 for handling local network, connecting to exchange etc. and NIC2 to handle files transfes to offsite location through seconday internet line.So now I have a desktop PC with two NICs. One of them built into the board, the other a pci add on nic. they are both 10/100
On nic1, there is a connection to my network 200.200.1.X which is the internal network for Exchange, local files transfers etc. This is the network i have always had connected and I have no problem connecting to my exchange server etc. (my server is providing dns/dhcp/wins/AD/MSE for the entire network)so I installed a secondary NIC and a secondary network line to the NIC2 on the machine.I set it up with an IP, a SN, a gateway and a DNSI removed the gateway from the 1st NIC.SO then I tried adding a gateway to BOTH of the NICs..This allows me to do EVERYTHING I want, however when i go to whatismyip.com and get a result, the IP it is giving me is NOT either of my static IPs (each network has a seperate internet line with a static IP). Not sure where this IP is coming from, but if i tracert google.com it says I am going out through the primary adaptor.The new IP from whatismyip.com makes no sense to me as it is not either of my static IPs, however it is very close.Would this be a situation where my ISP see's I have 2 gateways defined so it generates a 3rd external IP for some reason? Never heard of this but i am no guru.essentially I just need NIC1 for handling local network, connecting to exchange etc. and NIC2 to handle files transfers to offsite location through seconday internet line.
