NT 4.0: Hold ‘em or fold ‘em?

Is NT 4 obsolete or not? And should you upgrade?

overview
Overview
  • Who’s retiring NT 4.0?
  • Who ever heard of retiring an OS?
  • Is anyone still using NT 4.0?
  • Why is this different than other retirements?
  • Why or why not upgrade?
  • Should you be forced to upgrade?
  • The bug that might make you upgrade
  • How to upgrade for less money
retired
“Retired?”
  • You can’t buy NT 4.0 any more as of now
  • Currently: no support or hotfixes for NT 4.0 workstation
  • 1 Jan ’04: no more hotfixes except security holes for Server
  • 1 Jan ’05: no more premier or pay-per-incident support and no hotfixes no matter how bad the bug
  • (Side note: 98 dies in January)
whointheheck retires oses
Whointheheck retires OSes?
  • Actually it’s happened for years
  • For example, 95 and DOS and NT 4.0 workstation are retired
  • www.microsoft.com/windows/lifecycle/desktop/business/default.mspx has details
how do you know
How Do You Know?
  • Microsoft has a “life cycle support” policy announced last October
  • OSes are supported for seven years
    • Five years “mainstream”
    • Two years “extended” (still supported)
but people aren t upgrading why
But people aren’t upgradingWhy?
  • It’s not that 2003 or XP aren’t really neat tools
  • But change has a cost
  • See if this looks familiar:
evidence
Evidence
  • NT 4.0 is a seven year old OS
  • But people are still using it; in fact, many controller devices are only available in an NT 4.0 version
  • Imagine running NT 3.1 in 2000
  • Consider version skipping; how many go
    • SQL 6.5-7.0-2000-2003?
    • Windows 98-NT 4-2000-XP?
    • How many still use Exchange 5.5?
is something wrong
Is something wrong?
  • No, it’s a natural side effect of any technology maturing
  • That’s a significant point
  • Note that this is not advice… it’s observation
  • Some simply cannot afford to upgrade without a life-and-death reason … that’s important
  • But it also means that “being an expert” gets tougher – you must know a wider range of OSes
should i upgrade to 2000 2003 heavens yes if you can afford it
Should I Upgrade to 2000/2003?Heavens yes, if you can afford it
  • Plug and Play
  • Active Directory
  • Group Policies
  • Centralized patch control
  • More secure out of the box
  • Far more efficient in many ways
are there down sides
Are There Down-Sides?
  • Cost: licenses and CALs
  • Risk: AD radically changes your NT 4.0 domain structure
  • Hardware: lots of circa 1998 hardware can’t run 2000, XP or 2003
  • Time
advice before upgrading
Advice Before Upgrading
  • AD is the biggest part
  • It requires a fair amount of planning because AD has a lot of “one way doors”
  • 2003 has an advantage in that it’s a trifle more flexible
  • Fortunately there are nowadays many people with good solid experience who can help
  • If possible, do a clean rebuild rather than an upgrade
when is an os obsolete
When Is an OS Obsolete?
  • While I prefer the newer OSes, I think it’s wrong of Microsoft to give NT 4 users the gate
  • I think users determine obsolescence, not companies
  • Not everyone needs the latest thing, or needs it ENOUGH
  • Not everyone can afford the latest thing
  • Hardware does not obsolete OSes anymore
  • Seven-year-old software is not unusual at all in other markets
don t want to might have to the bug that might kill nt 4 0
Don’t Want To? Might have to!The bug that might kill NT 4.0
  • A security hole might convince you to upgrade
  • KB 331953 reveals a potential denial of service hole in the RPC port mapper, which uses port 135
  • Another “buffer overflow” problem
  • The same sort of problem as we saw in MS03-026
severity
Severity
  • Does not allow an attacker to steal data from a system
  • Affects NT 4, 2000 and XP
  • 2000 and XP patched
  • NT 4 ISN’T… no patches for it
architecturally impossible
“Architecturally Impossible?”
  • MS patched 2000 and XP, but not NT 4
  • Their reason: that it’s “architecturally impossible.”
  • This seems odd, as RPCs didn’t really CHANGE all that much from NT 4 to 2000… but there’s a 2000 fix
  • So with all respect, this seems suspect and, well, awfully convenient for MSFT shareholders
  • Which leads to the delicate “trust” issue
why this isn t acceptable
Why this isn’t acceptable
  • NT 4 has quite a bit of expected lifetime left
  • Unless they’re willing to buy the old copies back or offer free 2000 upgrades…
  • Merely saying “don’t put a system with port 135 on the Internet” is a workaround, not an answer – despite “expert” opinion, there’s nothing wrong with it, given patches, passwords and permissions
  • It supports what was basically NT’s main reason for existence for years… file serving
  • Worst of all, it sets a dangerous precedent
possible microsoft options
Possible Microsoft Options
  • Release a patch
  • Explain that the patch is impossible, and release source code to prove it
  • Develop a more complex patch and charge for it
  • Adopt the Pentium approach… offer free upgrades
  • Never have exposed the vulnerability in the first place if they knew they couldn’t fix it
final thought for those who want the new but can t afford it
Final Thought…for those who want the new but can’t afford it
