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
