Anyone know how a Microsoft DNS server handles CNAME records? We have a MS DNS server here, and when I do DNS lookups using UNIX tools, such as nslookup, dig, host, and the Python socket module, I get expected results for simple host name queries and reverse queries, but I get null sets for alias (CNAME) queries. I did this query using host: "host -t CNAME xxxx.lib.msu.edu" on one of our servers that has multiple aliases, and it came back with "xxxx.lib.msu.edu has no CNAME record" When I did a query using one of the aliases "host yyyy.lib.msu.edu" it returned "yyyy.lib.msu.edu is an alias for xxxx.lib.msu.edu" So apparently host can recognize an alias, but when you query a host name or IP for CNAME records, it finds none. Which makes me wonder if a CNAME record on a Microsoft DNS server is different from a CNAME record on non-Microsoft DNS servers. Thoughts?
