Can't get to our websites from 1 out of 3 offices

Were having an issue where our main office (Office A) cannot access any of the company websites or FTPs that are hosted with Webnet hosting.  Our other 2 offices (Offices B and C) can access all of these.

We have a Windows 2k3 R2 based domain that serves 3 offices.  Office A is the main site with the master DC also running DNS.  Offices B and C both have local DCs that get domain info from Office As DC and are each running DNS.  We have a hosted DNS with the ISP that all 3 offices share.  

We are also able to reach all websites and FTPs from our backup DSL connection from a different ISP that is not part of our domain and is not integrated into our main network.  This is also the case when trying to access from a PC that exists outside of our main network, router and domain, and is using a different public IP.  

So, the problem seems to be with our DNS. What issue would this problem?

Below are TRACERTs from all 3 offices, an independent PC in Office A that exists outside our domain and router with a dand our backup DSL connection at Office A.

on your Windows server do a 'route print' and check whether you have a route for the 192.168.3.0/24 network ?

Looks like youve got them for the 192.168.4.0 and 192.168.5.0 and 192.168.13.0 but not the .3.0 ?
