Solaris ssh client hangs when connecting to another Solaris machine

Got a strange problem.

I have 4 Solaris servers all configured the same, Solaris 10 x86 update 10.

When I try to ssh from one Solaris 10 server to another server ssh hangs.
I have an identical server and when I try this everything works fine.
The weird thing is if I am root on the server that isn't working when I ssh to another maching it doesn't hang.

Here is the debug output from ssh:

Code:

This was working until yesterday and I have made no changes to the systems.

Further information. This is using the stock Solaris ssh client. I also have the openssh client on the system in question and that works.
Just can't figure out what is going on.

Something must have changed. Issues are just the results of one or more causes Smilie

Well, for starters, can you delete the private key and generate new public/private key and check? (to be honest if there was key mismatch, it would prompt you for password; should not hang)

Also, check if DNS is enabled in the remote machines's ssh config. If so, is you DNS server responding to the queries properly?

Does it happen while connecting from a particular server?
