Recently I faced a Network issue while working on Windows server 2012 operating system.The error message was followed. An Attempt to Resolve the DNS name of a domain controller in the domain being joined has failed.

When we are trying to add a client in the domain, we always specify the domain name, domain controller resolves name in to IP and vice versa. In order to work a Domain Server properly we should configure reverse lookup zone, forward lookup zone automatically created at the time of DNS server installation.

LogZ is a Free Log Analyzer developed in php that retrieves data from raw log files and organizes it in an easy yet relevant way for further analysis. This can be used to help you update your blocked robots and crawlers lists as discussed in my previous post titled Practical Solutions for Blocking Spam, Bots and Scrapers. Before I even start explaining the features of LogZ Free Log Analyzer, I highly recommend you to read How to Identify User-Agents and IP Addresses for Blocking Bots and Crawlers to familiarized with basic concepts about User-Agents, Hostnames, and DNS Lookups. This explanation will also show you the steps taken to decide which bots and crawlers to block. Your browser sends this User-Agent header - shows the User-Agent string with details of your browser and your system.
Databases - are links to a couple of sources of information that provide details on bots and User-Agents. Date and Time - shows the date and time when the log files were downloaded from the server.
Sort by # of Visits - this link will take you to the list of User-Agents arranged by the number of visits made to the website. If you click on the LogZ logo you will be redirected to this post for questions and additional information.
For better navigation most links are in orange and will get underlined when the mouse is over. After clicking on Sort by UA you will be taken to the User-Agent listing section where the data is sorted in alphabetical order (#2 in the image below). You can sort the listing either way at anytime by clicking on the header title of each column.

In case you are wondering about the number of visits of a User-Agent, this amount is in direct proportion to the number of inclusions in the log file of this same UA.
Your good understanding of User-Agent strings will be vital to detect bad bots and crawlers in this section.
You can either lookup the suspicious User-Agent in the databases Bots vs Browsers or User-Agents, or do a quick search in any Search Engine using quotations for more precise results (i.e. The next step in the log file analysis process is to find out the IP Address or Hostname of the suspicious UA.
The third section contains data sorted by IP Address or Hostname (#1) and the number of visits. Unlike domain names, hostname labels can only be made up of the ASCII letters 'a' through 'z' (case-insensitive), the digits '0' through '9', and the hyphen.
As suggested in the best alternatives to identify undesirable bots and crawlers, performing Forward and Reverse DNS Lookups to validate the authenticity of a crawler is the way to go for maximum protection.
Moreover, running a Whois Lookup based on the User-Agent or IP Address to verify if the crawler falls into a legitimate IP range will give you an additional layer of confirmation. If you get a Hostname instead of an IP Address, you will have to perform a Forward DNS Lookup to find the respective IP. Simply click on DNS, select Reverse DNS, enter the information requested and hit 'Test it'. To check the Whois Record of a website, enter the Domain Name or IP Address in the box below. Using the IP Address of the suspicious bot, you can find all information of the company whose that IP corresponds to including email, phone number and other contact details. Sometimes locations vary depending on the Internet Service Provider (ISP) and other factors. A DNS Server, a Mail Server, an FTP Server, and other services can be hosted under one IP Address. Compare the domain name in the User-Agent string to determine whether it truly belongs to the Search Engine by checking the IP range of that UA. Last but not least, I would like to thank our friend and colleague Dmitriy Shabaev, on behalf of Spanish SEO, for making this script.

If you decide to use a different folder name, then change line 12 of logz.php and include the new folder path.

Otherwise, if you chose Sort by # of Visits in the prior section (#8 in the image above), it would have been sorted by the number of visits (#1 image below).
Should you want to re-arrange the listing according to the number of visits, then click on Sort by # of Visits (#1). With this information you can block the bot using the .htaccess code detailed in that post. In case there is a rogue bot using hosting services of a US based company, you can send the hosting company a Digital Millennium Copyright Act (DMCA) notice and takedown. If the IP range of this fake UA does not fall into Google's IP range, then most likely it is a rogue crawler. For instance, if a bot identifies itself as Googlebot, but it is not well aligned according to Reverse and Forward DNS Lookups, and its IP address is not within Google IP range, most likely this is a bad bot.

This User-Agent draws attention by not providing information in the string and having a potential association to the term Phyton programming language. If the information about the UA indicates that you should block it, then you can use any of the methods listed in Practical Solutions for Blocking Spam, Bots and Scrapers. Special characters other than the hyphen (and the dot between labels) are not allowed, although they are sometimes used anyway.

The application contains a set of tools including Ping, Traceroute, DNS Lookup, Reverse DNS, IP Whois, Domain Whois and Port Scan.
If you want to ping a host, for example, simply hit the Ping tab, enter the host address, rounds, and bytes size information, and click the Ping button.
This feature eliminates the need for using the Command Prompt and manually typing in commands for checking ping responses, which can simply confuse newbies.
