System time going AHEAD 100+ years
Good morning,
Any search on system time issues yields approx. 1,897,345,321 pages detailing problems with the CMOS battery. This is not that kind of problem. I support 200+ Windows XP SP2 systems, bought in batches over the years. About 20% are 5+ years old, about 20% are 6 - 12 months old, the rest fall in between. Random machines around the campus are coming up with date January 20, 2145, time about 7 hours ahead of correct time. Most of these machines use a generic user, member of the Users group, that cannot even *change* system time. Running a-v with current defs, have run mbam, sas, spybot s&d and hijack this, have not found any suspicious anything, other than the odd tracking cookie. Users of course cannot authenticate to secure sites, since certs are a century out of date. Windows time/date control panel won't even *allow* user to set date past 2099. Any thoughts? *Besides* CMOS batteries, I mean, since that would result in time going back to the 1990's or so, not ahead, and also would not be a problem on a variety of brand new machines? Thanks, tony |

Thanks, tony Are these all on Windows Domains? If so, take a look at the Domain Controllers as they may well be syncing time with them and one of those controllers could have the wrong date and time set on them (or wrong date + wrong regional setting, possibly GMT if your normal timezone is 7 hours offset from GMT). The apparent "random" setting could be due to them authenticating to different controllers each time they logon, and it only occurring when they do so against the misconfigured controller. -- Dan |

Hey, Dan,
Nope, I run a NetWare network, and all the NW servers know what time it is.... Thanks, that was an excellent thought!

Have these machines got the Windows time service updates running to update
automatically from the internet? Have you checked any of the machines that were affected to see what their NTP settings are? http://support.microsoft.com/kb/314054#EXTERNAL I'd suggest running a packet sniffer on the network and watching out for NTP broadcasts or requests. If the affected machines have the correct NTP settings then there may be a rogue machine on your network broadcast NTP time updates and that will be a pain to track down. I haven't touched NetWare since 4.11 so I'm out of my depth there, but there are NTP services for NetWare so I still wouldn't rule out a buggy/misconfigured time server.
