All hosts but one on a subnet cannot ping default-gateway

Hello. I'm sort of a newb at all this, shooting for my test shortly and what I have set up on packet tracer (just so I can get some practice setting up Wan configurations with a few routing protocols in.) a network that looks somewhat like this.

On one end, hooked up to a 3560 switch I have 13 desktops. The subnet is 192.168.1.0 /27. Host range from 2-15, the router the switch is directly linked to falls in the 192.168.1.1 address. That same router, an 1841, is hooked up on its s0/1/0 int to another router through a serial connection with PPP running on it. Both ends are set to PPP, both ends are running Chap and Pap, both ends have the usernames and passwords set up right. The two serial interfaces are set to a 192.168.1.32 /30 subnet. (192.168.1.33 and 34)

Routers are both running ospf.

192.168.1.34 is connected to another switch carrying three laptops. Subnet is 192.168.1.64 /29. Host range 192.168.1.66-68

Alright. Here's my problem.

All laptops can ping all routers and hosts on the 192.168.1.0 network.

All routers can ping each and every host connected to every subnet involved.

All but one random desktop in the 192.168.1.0 subnet can ping outside of the connected switch...

Any ideas?

Most than likely a desktop configuration issue, Windows Firewall?

Figured it out. Ran show running-config and saw I had RIP enabled on the router facing the network in question. Slightly embarrassed.
