SYMPTOMS
NSLOOKUP, which is included in Windows NT 4.0 Service Pack 4, does not devolve record queries for MX and NS records.

Prior to Windows NT 4.0 Service Pack 4, NSLOOKUP displayed the following output:   c:\nslookup > set q=mx > acmewho.com Server:  blue-dns.acmewho.com Address: 159.55.234.201

acmewho.com  MX preference = 10, mail exchanger = cool22.acmewho.com acmewho.com  MX preference = 10, mail exchanger = cool23.acmewho.com acmewho.com  MX preference = 10, mail exchanger = tilda1.acmewho.com >

In Service Pack 4, the following output is displayed for the same query:   > set q=mx > acmewho.com Server:  blue-dns.acmewho.com Address: 159.55.234.201

dns.acmewho.com primary name server = blue-dns.dns.acmewho.com responsible mail addr = ism.acmewho.com serial = 1140 refresh = 10800 (3 hours) retry  = 1800 (30 mins) expire = 2419200 (28 days) default TTL = 600 (10 mins)

If a trailing dot is specified, NSLOOKUP works as expected:   > set q=mx > acmewho.com. (note the trailing dot) Server:  blue-dns.acmewho.com Address: 159.55.234.201

acmewho.com  MX preference = 10, mail exchanger = cool22.acmewho.com acmewho.com  MX preference = 10, mail exchanger = cool23.acmewho.com acmewho.com  MX preference = 10, mail exchanger = tilda1.acmewho.com
