Win2K3 GP Problem - Internet Browsing

Server:
Windows 2003 Enterprise Edition
Internet Explorer 6 SP1

Workstations:
Windows XP Pro Sp1 (connected to domain not workgroup)
Internet Explorer 6 SP1

Using a Netcomm NB3300 ADSL Router/4 port hub.

Wireless Linksys-54G WAP.

On one workstation/laptop I am using Wireless and this can browse the internet without a problem.  With the LAN Based machines (Cat5e Cables) I have problems with the machines connecting to internet sites.  Local intranet sites are no problem and appear instantly.

The laptop with the wireless lan was plugged into the LAN and had the same problem, which led me to believe that there was a possible problem with the LAN connections.  So I purchased 3 more wireless links, but the machines are still erroring.

I would like to resolve this soon, as these are home machines in a networked environment, and I have a naggy wife :)

Hi development,

Do you home something you can replace the Netcomm NB3300 ADSL Router with to test if this is the problem?

Cheers,
IceRaven

Wish I did, the adsl modem/router is the only thing I have.  I'm not sure if it is the router though, because the laptop works with the wireless (WAP is plugged into modem/router).

I thought it could be cables, but when I changed the second LAN machine to Wireless, I got the same problem.

If there anything different about that machine that always works that you can think of?

What does it mean to be "Always On"?

Is your cloud always on? With an Always On cloud you won't have to worry about downtime for maintenance or software application code updates, ensuring that your bottom line isn't affected.

Not that I know of.  I checked the GP settings between both workstations and they looked the same.  I checked rsop.msc on both, and the one that was working was (X) on both computer and user settings...

Just downloaded group policy management snapin and unlinked/disabled the Default Domain Policy, to see if this is the issue.  I dont get home for another 3 hours, but no luck on the server machine so far.

Is the hardware the same?

Wireless hardware?  No, one is PCMCIA and the other is a USB Wireless Module.  I will try with the USB module tonight and see if there is a difference in the notebook.

Is the DNS configured the same for all the machines ?

Make sure that you do not have a proxy server set up unter Tools >> Internet Options >> Connections >> Lan settings in your internet explorer , especially if you have the Bypass Proxy for local addresses switched on.

hi, no proxy, DNS was configured the same on all machines (still is).  I reimaged the laptop with Wireless and now this machine does not work properly.  The only device I can browse without having delays are my PDA with wireless.

I converted all machines to wireless G and to be honest, wireless B was more stable...  

I did have SUS installed, but removed it, and the problems started after this, but I cannot be certain that this was the problem.

Problem fixed.  For some reason the MTU wasn't changed, but the internet stopped working.  I changed the MTU from 1460 to 1420 and everthing came back.  Now I have to stop kicking myself for wiping 3 machines :)
