Windows Network Problem

04.12.2007 UPDATE
CNET is reporting Windows DNS Flaw exploit
http://news.com.com/2100-7349_3-6175743.html?part=rss&tag=2547-1_3-0-5&subj=news
I’m not sure if this is the case.

Here’s the situation.

  • Windows 2000 Server acts as Domain Controller
  • Any DNS query errors redirected to 69.25.212.153
  • Effects computers in Domain/Active Directory running Windows 2000 and Windows XP

I suspect that there’s some kind of ARP Poisoning on the server itself.

I’ll update this soon…

The Trouble with Windows Patches

CNET News reported that “Windows cursor patch” is causing troubles on some computers. Apparently the update is not compatible with Realtek device drivers. The Windows cursor patch causes Realtek ethernet and audio drivers stop working.

I experienced the same thing on Tueasday (04.03.2007) after applying the Windows cursor patch on numerous computers. The audio devices stopped working and Windows reported a “generic svchost error” consistently. On some computers, the problem can be mitigated by reinstalling the drivers. On some other computers, the problem was a lot more severe.

A few weeks ago my coleague and I encountered a similar “generic svchost error” on numerous computers. The problem seemed to happen after Microsoft rolled out the new “Windows Genuine Advantage” update.

Boot Camp 1.2 beta and Windows Vista on MacBook Pro – Part 1

I installed Boot Camp 1.2 beta on my 15-inch MacBook Pro Core Duo 2.0GHz. I previously had an 8GB partition with Windows XP Professional installed on it. I started Windows Vista installation since Boot Camp 1.2 beta now supports it. It took about 20 minutes for Windows Vista Ultimate to install on my MacBook Pro; the installation went smoothly. After first log-in, I found out that I only had 6.5MB of free space on the Windows partition. At this point, there’s no way I could install the Macintosh Drivers provided by Boot Camp 1.2 beta.

Ah well, I had to repartition my hard drive. This time I will create a 12GB partition for Windows Vista. This will take a while since I don’t think Boot Camp can cleanly create a 12GB partition on my MacBook Pro hard drive.

I will post more on this.

My MacBook Pro specs:

  • 15-inch MacBook Pro Core Duo 2.0GHz
  • 2GB DDR 667MHz (PC5300)
  • 100GB 7200RPM Hard Drive
  • Radeon X1600 256MB VRAM

Airport Express and HP LaserJet 1020

I was helping friends (someones who wouldn’t compensate me at all) sharing an HP LaserJet 1020 using Airport Express. For some reason, the printer driver would not install at all. I tried it on their Windows XP computer and both of my Macs (PowerBook G4 and MacBook Pro). So far i have been unable to make the combination to work. I tested the Airport Express with LaserJet 3055, and the combination works.

As of know I’m not sure if it’s possible to share the HP LaserJet 1020 using Airport Express (through Bonjour).

Vista PC Reviewed: Gateway GT5404 Desktop

This Gateway® GT5404 Desktop is the first Vista PC’s I worked on shortly after Windows Vista was released.

Specifications
Processor: Intel® Pentium® D Processor 915 dual-core 64-bit processor with Intel® EM64T Technology
(2.8GHz, 800MHz FSB, 2 x 2MB L2 cache)

Out of the box, Gateway GT5404 Desktop is somewhat an adequate performer. The Intel Pentium D Processor 915 dual-core is powerful enough, but some may prefer Intel Core 2 Duo processors. It comes with 1GB of RAM (2x512MB) and an integrated Intel GMA 950 with up to 224MB shared video memory. That leaves 800MB of RAM to the system. Booting Windows Vista on this PC is a little bit painful. Right of the bat Windows Vista is using 700MB-900MB of RAM and settles around 500MB.
To increase the performance of this computer, consider upgrading the Memory to at least 2GB and/or installing a decent PCI-E Video Card with minimum of dedicated 128MB of video RAM.

This computer comes with an optical mouse and a USB-powered stereo speaker. The mouse is nice enough to use. The speaker lacks low frequency and sounds terrible when it comes to music.

Considering the specifications, it should be a relatively powerful computer with the exception with the integrated graphic card. Windows Vista feels a lot sluggish on this computer. Consider turning of the Sidebar to free up some resources. The graphic adapter is having trouble driving larger LCD flat panel. I tested it using Gateway 22″ LCD, Gateway 19″ LCD, and Samsung SyncMaster 940MW. At the LCD’s native and optimized resolutions, the display looks terrible. All three LCD flat panel looks blurry using the integrated Intel Graphics. I installed a PCI-Express based nVidia GeForce 7100GS with dedicated 128MB video RAM and DVI connector. After that the display look flawless. I replaced the 2x512MB PC4200 with 2x1GB PC5300 and Windows Vista runch a lot smoother.

I decided to downgrade the Operating System to Windows XP Pro. The device drivers for Windows XP are relatively easy to find on Gateway and Intel support site. Windows XP Pro runs great on this machine, with the exception on the integrated Intel Graphics. Once again, the display looks terrible when it’s connected to the built-in video card (VGA). With the nVidia GeForce 7100GS, the display once again looks flawless.

One complaint from user of this computer is the position of the ON/OFF switch. It is located on the top right of the front panel above the optical drive. The ON/OFF swith is often mistaken for the optical drive eject button. Gateway GT5408 Desktop does have the same design with this GT5404 model.

Overall, Gateway GT5404 Desktop is a good machine with the exception with the integrated graphic adapter. I’d recommend installing a PCI-Express video card to boost the performance. If you are sticking with Windows Vista, having 2GB of RAM will help a lot.
