CHALLANGE - rcp permission error - rsh working ok?

[solarworld]

Hello Unix Wizards - I have a challenge for you ===

I have 4 new solaris 11 vm servers that suppose to be a clone of each other and I have a requirement to enable and use rsh and rcp in full duplex mode. I have setup all the standard files (/etc/hosts, .rhosts) and verified the setup but I have this strange problem with one server only and not sure how to resolve short of starting from scratch??

I have tried truss command but did not see anything to indicate the problem - any and all ideas are welcome.

here is my problem:

login as root to server 1

rsh server2 <<--- ok and I can create/delete files

rcp -p /tmp/test server2:/tmp/test <<--- ok
rcp -p server2:/tmp/test /tmp/test <<--- ok

login as root to server 2

rsh server1 <<--- ok and I can create/delete files

rcp -p /tmp/test server1:/tmp/test <<--- ERROR - permission denied
rcp -p server1:/tmp/test /tmp/test <<--- ERROR - permission denied


login as root to server 3 or 4

rsh server3 <<--- ok and I can create/delete files

rcp -p /tmp/test server3:/tmp/test <<--- ok
rcp -p server3:/tmp/test /tmp/test <<--- ok
