I have been researching this for you.
When I look at components that handle DNSP packets, I see asserts in the checked builds that verify that DNS_RPC_NAME structures are DWORD aligned, so I'm inclined to believe that the documentation is correct. However, I have been trying to verify this myself. I used DNSMGR.DLL (the Admin snap-in via Start->Administrative Tools->DNS "DNS Manager") and captured MS-DNSP traffic.
However, that doesn't match your repro scenario at all.
You cited "MS-DNSP describes a DNS_RPC_NAME data structure in section 126.96.36.199.1. [...] Quering a Win2k8R2 server for DNS records via LDAP, it looks like the DNS_RPC_NAME structure is 2-byte-aligned [...]" When I do LDAP queries (via LDAPDE or "Active Directory Users and Computers"), I'm not seeing any MS_DNSP traffic.
So, can you help me repro the alignment issue you're seeing re MS-DNSP DNS_RPC_NAME 188.8.131.52.1 (with an emphasis on DNS_RPC_RECORD_SRV records). Or, is this issue involving something other than MS-DNSP?

Just a quick note that I am researching this for you.
