Client has Windstream (previously Nuvox) and has had for many years.  Network works fine.  6 to 8 months ago we installed a few new Windows 7 machines with no issues.  But within last 6 months, we've installed brand new Windows 7 systems on two networks, both with Windstream T-1 data circuits and in both offices we have the same problem.  But ONLY with these brand new out-of-the-box systems:

Some web pages hang or don't fully load.  Cannot connect to hosted Exchange servers.  When we bring the systems to our own network, everything works fine.  I've tried everything I know.  I figure some sort of DNS issues, but have tried manual DNS entries, to no avail.  

I'm just out of options.

thanks

Have you tried Google DNS 8.8.8.8 ?  If you ping the websites or hosted exchange server, do you get the proper responses?  

What firewalls are in place the remote sites with problems?

Yea, I did try the 8.8.8.8 DNS.  I get request timed out when pinging the hosted exchange server.  We're using a Cisco RV082 router/firewall. There are two active VPN tunnels to the same units at two other locations.  Again, only these brand new machines out of the box are experiencing this issue.  systems on other end are not having any issues either.

thanks!

Just for giggles, can you turn off the firewall on the new machines completely?

You said you get request timed out when pinging the hosted exchange server, but does the name resolve properly?   Do you also get request timed out when pinging from the known working computers?

Do you have any odd routing going on in the RV082?  What does the routing table show?  Do you have the same router at your location?

Compare a tracert output to the hosted exchange server from a computer that does not work and one that does work.  Do they take the same or very similar paths?

We figured this out.  Problem was outdated firmware on the router.  The other thing I noticed was the only new machines having the issues were all using Realtek PCIe GBE NICs.  So Realtek + outdated router firmware = inconsistent connectivity to Internet.

Thanks for the help.
