I recently uninstalled software that was provided by my employer in order to work remotely. Now I cannot access the Internet at all. In calling them, they had no solution. My assumption is that there still must be some type of barrier (firewall, etc) on my PC that is not allowing access to the Internet. I've looked over the files on my PC but do not know what else to do - does anyone have any suggestions? The software that was used for security was checkpoint secure remote.

Most firewalls have an icon in the system tray.

You can also check for running programs by opening Task Manager (Atl-Ctr-Del)

More likely, you need to re-install or change the settings for one of the following network services:

Dial-Up Networking
Client for Microsoft Networks
TCP/IP

On the PC that you used to access this site, go to the home page for your ISP, and print out the setup instructions.

Make sure that ALL services, protocols and settings are as required.

You need to check up back to the documents or files which your ISP had provided to you.
Because the program that you uninstalled may changed the your machine's setting.

1. Check your modem or NIC whether it is functioning.

2. Check your ISP'sdocument that they provided.

3. If you get net connection from behind of your LAN, & your LAN has setup the firewall & proxy, then you have to know your LAN's proxy IP & it's port to configure in your Internet Explorer's> Tools> Internet Options>connections Tab> LAN setting> check the proxy server & fill up it's IP & port.

4. If you're not from LAN, direct connect, then check your connection setting from Network & dialup connections from setting, start menu.

well, there are various kinds of connections are listed, so you have to be sure of what connection type that you use. If you use dialup, besure of your ISP's server's Ph: number or If you use VPN, then be sure of your ISP server's IP address, type of VPN protocol.

Another possibility is your User ID & your Password for the access.

Hope you can fix it.
& I'll try my best.
Thanks.

What type of Internet connection do you have - dialup or broadband? Check the settings for whichever type you have - for a dial-up connection, check the properties of that dial-up, for a broadband connection, check the properties of your NIC card that connects to your broadband modem or router. Make sure that the TCP/IP protocol is installed and bound to the NIC or dial-up connection. It's possible that when you uninstalled the Secure Remote client, the uninstall also removed TCP/IP. It mayhave even removed the NIC drivers and/or dial-up connection itself, depending upon how it was set up, so check these also. If you're not too savvy, the easiest thing to do would probably be to go back to your ISP and have them walk you through setting up your connection all over again. Hope this helps!

No answer but more info needed.
Are you trying to connect via, and as part of the LAN of your employer? Or are you using the PC outside the employers environment? These are crucial items to be able to find out where your problem(s) is/are.

Thanks to clarify.

If we knew the software name that you uninstalled, it might lead to an easy answer.

As stated before, information is needed about the type of connection and a general description of your environment, i.e. wireless, firewall, router, switch, etc.

I would check your Internet Properties under the Connection tab AND if you're not using a dial-up modem check the option to "Never Dial A Connection." Then run the setup at the top of the menu. Make sure you apply the correct settings.

If you've got a firewall, find out which kind and download the Manual from the vendor. They will have instructions.
