Hi all,

By making use of .NET classes, how can I accomplish the following nslookup command without making use of the command prompt window:

MSIL

C:\Users\userA>nslookup
Default Server:  server.domain.local
Address:  192.168.0.1
> set type=srv
> _ldap._tcp.domain.local
Server:  server.domain.local
Address:  192.168.0.1
_ldap._tcp.domain.local  SRV service location:
          priority       = 1
          weight         = 1
          port           = 0
          svr hostname   = requiredServerName.domain.local
requiredServerName.domain.local  internet address = 192.168.0.2
>

Many thanks in advance.
Kind regards,

Hi all,

This is how to do it:

Download the following assembly from CodePlex: DnDns and PocketDnDns - A .NET DNS Client Resolver Library[^]

Implement the following piece of code (DnsQueryResponse contains all the desired information):

DnsQueryRequest request = new DnsQueryRequest();
            DnsQueryResponse response = request.Resolve("192.168.0.1", "_ldap._tcp.domain.local", DnDns.Enums.NsType.SRV, DnDns.Enums.NsClass.ANY, System.Net.Sockets.ProtocolType.Tcp);

Kind regards,
