DNSCMD is partially blocked after upgrading to Windows Server 2008 R2 domain controllers - Why?

Having some trouble with DNSCMD.EXE utility that is provided with Windows Server 2008 R2. With some options get an expected result. Other DNSCMD options print a line feed in the command window but no error and no expected results.

I suspect the problem has something to do with the fact that others in our company recently upgraded some domain controllers to Windows Server 2008 R2.

I can run commands locally on one of our Windows Server 2008 R2 domain controllers (Active Directory is at the 2003 level). The problem is when I attempt to run DNSCMD on a client (the source computer).

Examples that work:

   dnscmd.exe server1.my.com /enumzones

   dnscmd.exe server1.my.com /statistics

Examples that do not work:

   dnscmd.exe server1.my.com /info

   dnscmd.exe server1.my.com /zoneinfo

   dnscmd.exe server1.my.com /zoneexport

I am a domain administrator and both the source (Windows 7 Enterprise) and target (Windows Server 2008 R2 domain controller running DNS service) are in a single domain. I can run the Administrative Tool "DNS Manager" GUI remotely, no errors.

The following output from DNSCMD when run locally on a domain controller may offer some insight into the problem:

P.S. My original question "How to consistently get output from DNSCMD.EXE tool?" (http://social.technet.microsoft.com/Forums/en-US/winserverNIS/thread/a1889413-41d1-45c3-9b28-d8ae8c4cffde) is marked asanswered by the moderator, but the question is not answered! So I am starting this new thread.
