The story about this security bulletin has hit Slashdot. While there realistically won’t be too many customers who’ll trust NT4 systems on a un-firewalled network, this will seriously impact Microsoft’s credibility in the enterprise space (a space where it needs all the credibility it can get) because it reneged on its own lifecycle policy of providing hotfixes ’til Dec 2003 and security-related hotfixes ’til Dec 2004. IBM teams (which have consistently provided support for their products — including clunkers like PC DOS — for 7+ years) must be smiling.
