Quickly Check Domain Computers (Servers) for MS17-010 Patches

I put this script together from a few different sources.  It basically enumerates Active Directory and checks any 2008+ server for existence of KB patch for MS17-010.
MS17-010 patches a critical vulnerability discovered in Microsoft Windows operating systems that involve SMB exploits from a ShadowBrokers NSA dump of leaked NSA hacking tools.  It’s been spreading from CPU miner payloads to Ransomware (WannaCry/WannaCry 2.0) etc.
