Pulling my hair out

I have 4 point to point T1 connections with cisco 1841 routers connecting to one cisco 2800 router. Everyone can communicate fine except: the 1841's cant ping 3 ip's on the class c network that is attatched to the 2800 router. They can ping all of the other ip's on the same subnet. There are no access lists involved. When I traceroute from a branch router to one of the IP's it stop's after the cisco 2800. Example from branch cisco 1841:

Tracing the route to xxx.xx.93.5

1 xxx.xxx.96.1 4 msec 4 msec 4 msec (this is the cisco 2800 interface)
2 * * *
3 * * *

Then I look at the Cisco 2800:

Tracing the route to (xxx.xxx.93.5)

1 xxx.xxx.93.5 0 msec 4 msec 0 msec (works fine)

---

try the same thing from branch cisco 1841 to another IP on same subnet:

Tracing the route to xxx.xxx.93.2

1 xxx.xxx.96.1 4 msec 4 msec 4 msec
2 xxx.xxx.93.2 4 msec 4 msec 4 msec


Anyone have any suggestions?

What are you trying to ping? From the traceroute it looks to be good all the way up t the 2800, maybe the device just isn't responding or has a client firewall.
