To perform an NSLOOKUP query against Active Directory, you can use the `nslookup` command within a Command Prompt or Terminal window. Here's how you can do it:
1. Open Command Prompt (Windows) or Terminal (macOS/Linux).
2. Type `nslookup` followed by the name or IP address you want to query. For example, if you want to check the IP address of a domain controller named `dc.example.com`, you would enter:
```shell
nslookup dc.example.com
```
If you want to check the reverse DNS lookup for an IP address, you would enter:
```shell
nslookup <IP_address>
```
Replace `<IP_address>` with the actual IP address you want to query.
3. Press Enter to run the command.
4. The output will display the results of the NSLOOKUP query. It typically includes the IP address and hostname of the queried domain controller or the reverse DNS lookup result.
Please note that NSLOOKUP queries rely on DNS resolution and the availability of DNS records. Ensure that your DNS settings are properly configured and that you have network connectivity to the DNS server or Active Directory domain.
