Annoying EIGRP Error Message

Hi,
Can anyone throw any light on this.
I have 2 x routers (877's) connected to a LAN. The IP's of each are
192.168.142.201 & 202 respectively with 200 being the HSRP address. They are
connected to a small Hub so I have set the Fa0 ports on both to run at Half
Duplex 10Mbs. Both run EIGRP (process 10) and advertise 192.168.142.0
0.0.0.255 with no-auto-summary configured.
I can ping from 202 to 201 but not the other way around. There are no
access-lists on the Ethernets.
I see the following error message pop up:
R01#
*Mar 12 01:30:51.766: %DUAL-5-NBRCHANGE: IP-EIGRP(0) 10: Neighbor
192.168.142.202 (Vlan1) is down: retry limit exceeded

Mar 12 01:30:52.218: %DUAL-5-NBRCHANGE: IP-EIGRP(0) 10: Neighbor
192.168.142.202 (Vlan1) is up: new adjacency
Router configs as follows:
R1 - Ethernet interface Vlan1
interface Vlan1
ip address 192.168.142.201 255.255.255.0
no ip redirects

Thanks Merv,
I won't have access to the routers for another week as I am not going back to the site I installed them until then. I will post a follow e-mail with the output requested.
Just seems so crazy that this didn't work. The only 2 x things plugged into the Hub were the 2 x 877's. I ruled out a hardware problem as 1 x router could contact the other but not the other way round. More news to follow.
Regards
Darren

take a crossover cable with you and make sure that the ping issue does not occur when connected back to back (i.e. not thru the hub)
not being able to ping in both direction is not a good situation ...

to find out why pings are failing, try
conf t logging buffer 10000 debug no logging console exit
wri mem
debug icmp
! run ping tests
show log
also try using extended ping and specify the source IP address

Merv,
Apologies for me taking so long to reply. Never got the chance to revisit this until recently.
Turns out that one of the routers had an access-list on it's VLAN1 interface that blocked eigrp. I made the mistake of e-mailing my template output form the text file I then applied to the routers. I didn't take the output from the actual router config. Somewhere along the way I added the access-list by mistake to the VLAN interface. The same access-list was also applied to the dialer interface as well.
Obviously a case of me not paying attention to what I was doing.
Thanks for your help in the 1st instance.
Regards
