Using 2 network interfaces in Windows XP

by hemlock70 / December 18, 2007 6:51 PM PST

Can someone please help me? I have an internal office network that is extremely restrictive, blocking a very wide range of internet sites like yahoo mail, gmail etc. The PC is connected to this network, but has a seperate GSM based modem which can connect to the internet via a local ISP. Problem is, when I connect via the external modem, any internal connection I have to email (exchange) / internal servers (iseries, unix) is dropped. What routing rules need to be created or is there a software piece to graphically enable applications to use a specific IP address? ie. mozilla only uses 1 IP, while exchange uses the other? Please help

And the Office/System Administrators Have Approved This?
by Grif Thomas Forum moderator / December 19, 2007 3:49 AM PST

Our forum policies prevent us from discussing methods for hacking a system.. But if you've got approval from management and they would be willing to fork out a little money for the specialized computer, it might be easier to simply set up a second computer which connects to the secondary modem.. Using a KVM switch would then allow you to use one monitor, one mouse, and one keyboard but switch between screens.

Hope this helps.

Didn't realise I was gonna meet the network police....lol

I didn't realise I needed to disclose the reason for 2nd network, but essentially, the GSM connection allows the use of automated SMS through SMTP alert capture from an iseries. Therefore having 2 connections, one to internal network and one to GSM network, the pc can directly sms out SMTP trap messages. So it's still required for the one pc.

I haven't check this for XP, but works in win98se

Open the programs you use with the LAN and leave them open. Connect with the modem and then open the browser/email program you want to use. In win98 that will allow those programs which already found and are using the LAN to do so. Since browsers default or look first for a dialup connection, and especially if you set that particular browser to do so in addition, then you can be using both connections at the same time. You just make sure to open the browser you intend to use with the dialup service AFTER connecting so it will see that first instead of the LAN.

Help, my PC with Windows 10 won't shut down properly

Since upgrading to Windows 10 my computer won't shut down properly. I use the menu button shutdown and the screen goes blank, but the system does not fully shut down. The only way to get it to shut down is to hold the physical power button down till it shuts down. Any suggestions?
