NSLOOKUP Does Not Devolve MX Record Queries

This article was previously published under Q214544
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
