Submission + - Vista TCP Window Stacking Causing Slowdowns

tridium writes: I recently moved into a new place where the landlord left a Linksys WRT54G ver2 router for us to use. Three laptops in the house running XP connected to it fine, but my desktop, running Vista RC1 build 5600, had to be hardwired. The Internet worked fine for a bit, but I noticed some websites weren't loading up (google, gmail, gamespot, etc.), and all IM clients were non-existent. Vista's self-diagnosis said to bypass Port 80 in the firewall (when the firewall on the router and desktop were off) and that it couldn't communicate with the DNS server, so I researched and the new TCP window stacking protocol in Windows is wreaking havoc with my router. I upgraded the firmware from Linksys, tried manually setting IP settings, modified the registry to disable TCP window stacking, but to no avail. Linksys support was useless saying they couldn't help with my "operating system configuration." I'm at a loss and any help, short of downgrading to XP, would be greatly appreciated!

Submission + - Daylight Saving Time change and datacenters

Cheeze writes: As I am sure some of you know, Daylight Saving Time is slated to change this year thanks to The Energy Policy Act of 2005. This means nothing to the large majority of the population except they will either sleep late one day or have to commute in the dark. To a select few, this is a crunch time akin to the y2k fiasco, only there has been almost zero publicity recently. These select few are the ones responsible for updating the millions of computers, both servers and workstations, with the new time zone information. For newer servers, this usually means just install a patch and reboot (which is slightly more than mildly inconvenient). For older servers, this is basically an "End of Life" declaration. Servers running software for which no patch is available will be unable to update their own clocks. This doesn't seem like such a big deal until you realize Microsoft is only offering patches for WindowsXP and newer and Sun is not supporting Solaris 7 and older. That should knock a large percentage of the computers 1 hour off for a few weeks this spring. What are you doing in your datacenter to prepare?

Adobe Acrobat JavaScript Execution Bug 94

QASec.com writes to mention that Stefano Di Paola and Giorgio Fedon discovered an unpatched vulnerability in Adobe Acrobat Reader that can allow an attacker to execute arbitrary JavaScript on any hosted PDF file. People are reporting different results based on browser and Acrobat versions. Most of the major sites discussed have already fixed the problem, but many smaller sites may still need to be patched.
