Question

Can get to a website from the server but not from a workstation behind it..

Asked by: sabot7726

Hello all,

I have a small test network with win2k3 sbs as the domain controller and a few workstations running xp. From the server, I am able to navigate to http://upload.dsgi.com, but I am not able to get there from any other machine on this network, which is causing problems because I need to be able to upload files to that site on a daily basis.

For troubleshooting purposes the specific workstation I'm trying from is not running any form of personal firewall, I even removed the windows firewall via group policy to see if that was the problem. I've tried versions of MSIE, Chrome and Firefox with no luck, including playing with every security option I could find in each browser. From the workstation I am not able to ping or tracert to upload.dsgi.com either.

The server itself does not have any fancy firewall other than what comes with sbs 2003. There is no hardware firewall on this test network.

The workstations are using the server as the default gateway.

It doesn't make any sense to me that the server can get to upload.dsgi.com but the workstations can't. What else should I try? :)

What are the DNS settings on your workstations?

 

by: sabot7726Posted on 2009-10-29 at 10:02:06ID: 25695755

They're set to use the same ip as the default gateway - 192.168.20.4 (which is also the sbs server), then the server's DNS settings are set to normal internet DNS's

Is this the only site you are having issues with?

 

by: sabot7726Posted on 2009-10-30 at 07:35:31ID: 25703347

Yes that I know of. It's never come up before in 4 years till now.

 

by: OOsorioPosted on 2009-10-30 at 09:55:16ID: 25704822

Maybe a patch update created the problem. Try changing the stations gateway IP to the internal IP of the internet router/modem.

Thanks, this worked. I still need to figure out why my SBS default settings don't allow traffic inside my network to access this specific site, but for now I'm just happy it works :)
