Hi guys !!
I have just recently started hack the box , and i am trying to learn the concepts as i go along .
Going through the walkthrough for the machine ARCHETYPE , it said that we needed to type the command IS_SRVROLEMEMBER ,
Searching on google for a while i found that it was a T-SQL command but nothing indicated that it was a common command used .
My question is how would i know to use these types of uncommon commands in upcoming machines if i dont even know that they exist.
Should i just learn T-SQL before going on further ?
