I have the exact same problem. I first thought it was Windows 7 (which I am sure still has something to do with it) until I just added a second Windows 7 to our network. I have been having this problem for weeks on end. Now with this second computer being a laptop, I brought it over to the router, disconnect the server input and connect the laptop directly to it and now have total internet access. I tried plugging back the server to the router while the laptop is still connected, and I am unable to browse most websites again. The router/modem is Speadstream 6520 Our server is Windows 2008 Server Standard We have 20 users, 17 use XP, 1 Win 98 and 2 Windows 7, all Pro versions Both Windows 7 clients are unable to browse the internet. (except a handful of sites) I have also tried SP1, removing from domain to no avail. I have read close to a hundred different stories about this problem but now I have found out it has something to do with Server 2008 Standard. The roles our server plays is DHCP, ADDS, DNS, Printserver and fileserver If there is an update or something to configure, I am dying to find it. ThanksCarsten

I'm setting up a laptop on a domain. For the most part it works as I expect. BUT, I'm unable to download files and/or updates from a number of sites. Some of the sites are www.java.com (for, you guessed it, Java updates), www.canon.com (print drivers), McAfee (for McAfee updates). On any other PC at the site, I'm able to download the above files/updates (the machines are WinXP Pro). I find that if I open the Cisco router ports up from this PC, I can download the files (naturally, I returned the config to keep it secure). I've updated the router, but to no avail. Some of the other "fixes" I've tried: I've run ipconfig /release, /renew & /flushdns This Domain has both wireless and wired - doesn't make a difference. I've updated the network card driver I can take the laptop to another site, which is an unreleated domain, plug the network cable in and downloads work fine. There are two business in the same building, both of which use the same ISP connection (Comcast), but that connection is fed into two each businesses' routers. I connected it to the other businesses' network. It still has the same problem. Logged in as Local/Admin I've uninstalled the AV program McAfee (now it's back on) I've disabled Windows Defender I haven't: Removed it from the domain and tested it Updated it to Win7 64-bit SP1 Reinstalled the OS Any troubleshooting tips are appreciated, or better yet, the answer is appreciated! Thank you. Rich

For a test, try to use static IP address instead of DHCP. Please post back with the result.Bob Lin, MS-MVP Networking, Internet, Routing, VPN Troubleshooting on http://www.ChicagoTech.net How to Setup Windows, Network, VPN & Remote Access on http://www.howtonetworking.com

Well I would advise against it for now. I wish that I could find the problem, I have read where you disable then re-enable nic card, this actually worked for a couple of days so I was sure it was a driver problem, but it is not... I have the latest signed drivers and still have the problems. Funny that the HP laptop that I installed yesterday on the network has downloaded all the MS updates, yet I cannot got to msn.com. So you are able to browse all websites, you just have a problem downloading? My biggest problem is that our mail is hosted on-line, and unless I can get this problem fixed, the VP will not be able to receive his mail...In other words I have to get this fixed before Monday.Carsten

Interesting, Carsten, The laptop I'm dealing with is able to get to the web sites I point the browser to (and I have IE8 and the latest Firefox browsers installed) starts the download, but rarely gets beyond 1%. The laptop I have is a Dell Latitude E6410. The server is Windows 2003 SBS, responsible for DHCP and DNS. Since I've set up a number of other PC's for a network within the same bldg (same ISP connection, but different router/switches) with Win7 64-bit that work fine, I thought it was just "one of those things". The other PC's I set up are also Dells, but they're desktops, Optiplex 780's. Considering the additional time I could put into the situation, I'm thinking of rebuilding the PC with a "standard" Win7 64-bit install, but now I'm wondering if it will work. Rich

I did disable the NIC, then re-enabled it. No difference. Then I deleted it, rebooted and re-installed it. No difference. As far as MS updates go, I wasn't sure if they worked at the site since I had it updated before I took it over. HOWEVER, I noticed that when I took it back to my location, where it was setup and worked after I found it wouldn't work at the client's site, then took it back to the client's site, one of the times I rebooted, it was installing windows updates. The default web site, which I haven't changed was msn.com - it went there fine and to java.com and canon.com and a few others - I didn't seem to have a problem there, but I didn't test extensively. When I have a chance, I'm going to test FTP (with Windows Explorer and, possibly, FileZilla if Explorer doesn't work). Ugh. Still trying . . .

Well I found the answer to my problems, pretty stupid when you think about it. I came across a thread where it said that it was not a good idea to point to 2 different DNS's. Our DHCP instructed clients to use both the internal DNS server and Modem as alternative. IE 1st 192.168.0.199 Server, 2nd 192.168.0.1 Modem So I dropped the 2nd DNS server and had clients only look at the internal DNS server and set-up forwarding on it. (Reason to have both was that if the server was down, you could still surf the internet.) Well this did not work but it got me thinking. Looking at my DHCP set-up there were 2 entries for router (Default gateway) 1 pointing to the Modem and 1 pointing to the server. So I figure that I would do the same thing that I did with the server and drop the Modem entry. Well did not work, but I started having the same problem with none Win7 clients. So I changed the router entry to only point at the Modem and not the server and Voila everything is now working. Why my original set-up worked fine for years (Advanced server 2000 through to Server 2008 Standard) is beyond me. So now DHCP tells clients to look only at the Internal DNS and look only at the Modem as a Gateway. My only worry now is if the modem goes down, so will the whole internal network???? I hope this works for you!Carsten

This is a good case. One fo our clients had the same issue. He wanted to have internet redundancy so that he had two ISP and added two routers on the DHCP. In most cases, it works. Howefver, it may cause the problem until we removed one of router from the DHCP.

Bob/Carsten, Against Carsten's earlier advice, I did a clean install of Win7 64-bit on the laptop in question. I did the install UN-attached to any networking. (This means that I did not install Windows updates or any other OS software (such as Office).) On another PC, I downloaded to USB key and installed needed drivers. I then took the laptop to the site, installed McAfee (still unattached to any networking, and NOT joined to the domain), shut the PC down, plugged the network cable in and booted. I first ran McAfee update. It wouldn't download the McAfee updates. I also tested Java, MS Windows updates; none download. Per Bob Lin's suggestion, I tried a static IP address. That made no difference. The machine is a Dell Latitude E6410. Coincidentally, my work machine's hard drive developed issues, so I've replaced the machine with the same model (same OS: Win7 64-bit Professional). I took my new laptop to the site, plugged the network cable in, and I duplicated the problem - I could not download Java or other files. (My machine, was of course, updated with Win7 updates (except SP1), had the same version of McAfee installed, and joined to my workplace's domain.) The issue, as has been implied/inferred (and everything else) is an interplay between Win7 and the networking infrastructure. I think once the problem is straightened out, the network will be more secure and efficient. BUT WHAT THE HECK IS THE PROBLEM? Thank you for input . . . I'll keep this thread updated. Rich

Hi Rich Sorry you are still having problems. Did you look into my solution? Can you run an ipconfig and post it here. When you said you plugged in the network cable, was it into a switch or router or directly into the modem. When you tried using static IP, what did you use as a default gateway and what did you use as a DNS. Finally did you try unchecking IPv6 ThanksCarsten
