Cannot access internet from Wingate server - clients can

[ggiebler]

I can't seem to access the internet via the web browser on the Wingate server. I get the message: "Internet Explorer cannot display the webpage. Most likely causes:
You are not connected to the Internet.
The website is encountering problems.
There might be a typing error in the address.

When I try to ping a site such as http://www.microsoft.com from the Wingate server, I get the message: "Ping request could not find host microsoft.com. Please check the name and try again."

I can access the web via any of our other client browsers, which connect through the Wingate server. Pinging microsoft.com from a client gives the following:
Pinging lb1.www.ms.akadns.net [65.55.21.250] with 32 bytes of data:
Request timed out.
Request timed out.
Request timed out.
Request timed out.

This all started to happen when I did some messing with the network connections on the external NIC of the Wingate server because I am trying to connect the server to the internet via a new DSL router which we just got, using another ISP. When I couldn't get that to work, I reset the network connections settings (TCP IP properties) for the external NIC back to their old settings and reconnected via our old router and the old ISP (which we have not disconnected yet since we are waiting to get the new system working with the new ISP first).

After doing so, client browsers and email clients again work fine, but the Wingate server has somehow lost its connection to the internet. Before I started messing around, the browser on the Wingate server worked fine, and I think pinging from either the Wingate server or the clients would give me a reply from sites on the internet. I've tried setting the Wingate server's internet connection options LAN settings to not use the Wingate proxy server, but that didn't help. I also tried rebooting the Wngate server. Again, this didn't help. Neither did merging a Wingate registry backup from a few days ago, which was before I started messing around with the network settings.

Any help would be appreciated. Thanks.

Are you able to ping the router itself?

Can you post up your IPConfig of the WinGate server.
Start -> Run -> cmd -> ipconfig /all

Yes, I can ping the router and it replies.
Here is the ipconfig /all results:

Was wondering how you have your internet connection set in the browser on the server?

We have set a binding to 127.0.0.1 in Wingate on the server and set the Internet Connections LAN setting in the browser to point to 127.0.0.1 port 80. That works OK for us.

also, may need to check DNS. If that server failed ping to find www.microsoft.com, that indicates a DNS issue. WinGate uses the same DNS servers as the host OS does, but uses a different algorithm to choose which one to use depending on responsiveness.
