[THIN] Communication problem?

We are attempting to setup a couple of citrix PS 4.5 servers (w2k3) in an existing test farm.

We have added the servers and everything seems to work (published apps, logon…) except for the following:

Servers are reporting down when we look in the CPS Console.
        Odd thing is that in the Access Suite console I can view the Resource manager logs and it is reporting Resource Manager Metrics in there.

When we look at the Resource Manager tab for the "folder they are in" they go from Loading… to Down to OK but if we double click on one of them it goes to the Resource Manager Tab for the server and reports Server down.

If I rightclick on the server and select Resource Manager Server Log I get this error: An error occurred while retrieving the server log from the server XXXXXX.  This may be due to network error…. Error code c0160ae3 (reviewing this http://support.citrix.com/article/CTX101581 but not applicable to this version, and this http://support.citrix.com/article/CTX104005)

Other servers in the farm are reporting fine.

I tried disabling firewall. (did not do a reboot but restarted IMA) did not seem to make and difference.
Checked some rights which are set via GP.  Made some changes, based on document on Citrix site which identifies local accounts and rights,  but did not seem to make a dif and another server in another 4.5 farm has the same rights and no issue.

Any Idea what could be going on?
