Slow client internet access
I have recently set up my network at my new office using a new Windows Server 2008 r2. Everything is working well, apart from the clients internet access is slow. Some website display a page cannot be found message and then when the page is refreshed the website is loaded. The clients web access is generally slow.
I have a Windows Server 2008 which has 2 NICS (one LAN and one WAN). The WAN NIC is connected to my Draytek router which is connected to the internet. All client computer use the server as a DC, DNS and gateway. To service the clients with internet the server is running Routing and Remote Access.
The internet access on the server itself is very fast.
Any help would be greatly appreciated.
Thanks,
John

Don't use your router as destination for a DNS helper, try and use your ISP's DNS servers if you are using forwarders.

Would it be easier to just change the default gateway of the clients computers to be the IP address of my draytek router? Would that be the easiest way to solve this issue?

Ps - the DNS setup is just the default one after adding the DNS role. I have not added any DNS entries.

I have setup a DNS forwarder on the server to googles DNS of 8.8.8.8.
I'll see if that works.

Check your DNS forwarder.
DNS related Slow Internet depends on the timeout duration, how many forwarder address you have and the sequence on the list.
If DNS fails to contact or resolve an address using the first forwarder on the list, it waits for the timeout to elapse and checks with the next forwarder address and so on until there is no more forwarder address.
DNS will now resolve to the root hint (if the check box "use root hints if no forwarder address is available" is checked).
So if your Internet speed is DNS related, that is the first thing you want to check. It is also best practice to enable automatic scavenging of stale records to make sure the table is not overfilled or contains stale records.
If you have issues with forwarder address, you may as well eliminate them. There are advantages and disadvantages, but it all depends on what is suitable for your network.
Forwarders are usually faster as they technically would handle less queries compared to the root hints. Root hints are almost always available and may be faster if your forwarders are not readily available.

Thanks for all of your help.
I ended up just disabling RRAS on the server and I just used my DrayTek router as the default gateway.
I then changed the DHCP settings appropriately.
Everything is now working perfectly.....
Thanks again.

what is your DNS server config? Do you use DNS forwarders or root servers?
