HijackThis log file analysisHijackThis is a program used by experienced users in order to detect browser hijackers. It allows you to identify any sort of spyware and malware (as well as some trojan horses and worms). This is achieved by scanning special zones of the registry as well as the hard disk drive, the results being listed in a structured window. Another feature of HijackThis is the creation of a log file, which can be saved as a simple text file and opened by any text editor (notepad as default). Until now, inexperienced users, who could not analyze the log file by themselves, had no other choice than posting it in a specialized forum and to hope that a more experienced user takes some time to analyze it. The script presented on this page is a way to analyze your log without help from the outside: simply copy/paste the content of the log file in the textbox below and hit the analyze button. HijackThis is free and does not need to be installed.

The Terabyte Saga Ends
The computer is up and running without a problem. It seems that Intel has different 2.8 GHz chips.

To quote http://techreport.com/reviews/2004q1/p4-prescott/index.x?pg=1
Prescott clock speeds will initially range from 2.8GHz to 3.4GHz. To keep Prescott-based P4s distinct from older "Northwood" cores, Intel is tacking an "E" on to the product names, so they'll be called the Pentium 4 2.8E or 3.2E. The product mix gets most confusing at 2.8GHz, where one could buy four different Pentium 4s: the 2.8GHz (a Northwood core with a 533MHz front-side bus), the 2.8C (Northwood again, but with an 800MHz bus), the 2.8A (Prescott with a 533MHz bus), or the 2.8E (Prescott with 800MHz bus). Clear as mud?

The motherboard I was so crazy about only uses the 2.8 Northwood chip but CDW sent me the 2.8a chip. In fact they don't even sell the Nothwood chip. The kicker is CDW won't take back the Intel chips

This past weekend I spent 10 hours removing spyware and viruses from one computer. I see from .this that it is not so unusual.

So the replacement board arrived to day from CDW. At the day's end, I carefully unwrapped it, installed the CPU and heatsink and tried again. Same problem! Is the the Power Supply faulty? I doubt it.

The Terabyte Saga Continues
The server is still not built. First of all, the system board appears to not be working. I get no beeps. It is acting as if there is no CPU in the board. There is an LED labled D1 that is amber instead of green. So I shipped the board back to CDW. I told my account rep that I want them to test the replacement board before they ship it to me.
Second of all, the wonderful 300 GB SATA drives from Maxtor which CDW claims will come in 2 weeks or less, still have not arrived.
Friday, Antec sent a replacement for the temperature probe that only registered in centugrade. They also sent me a speeaker because the speaker did not come with one.

Antec P160 Computer Case
The Saga continues:
This case is definitely not made for business use. It has 2 USB and 1 firewire connector in the front. The mboard that I am using has no usb headers. The case has no speakers only ports for stereo speakers. And the temperature gauge only displayed the temp in celcius.
I called their tech support and they will be sending me a free speaker for the case and a replacement for the probe and readout.
This was an expensive case. I'm glad I didn't have to get an RMA.

"Tyan's Trinity GC-SL motherboard" I am having the following problems getting this board working.
1.Board does not have it's own speaker like many boards do.
2. Board will not start because it says the CPU is overheating which could only be to
3. Retention clip does not hold down the heatsink well.
----------------------------------------------------------------
I got a speaker for the board, in addition Antec will be sending me a speaker for the case and I can then take my speaker home. No beeps
To see if the cpu had died I bought a celeron cpu being very careful to install it properly.
My conclusion is that the board is just no good!
This means I will now have to find a replacement board.

I see today that there are real disagreements about the articles that I read before ordering the parts. Here there is a comment:

• Mobo-SuperMicro's X5DPE-G2-O.
• Gives us two Gigabit NICs onboard, as well as an onboard ATi Rage XL
• Plenty of PCI-X slots though. $300.
• CPU? 2.4GHz Xeon (533FSB). $230.
• Memory? 512MB DDR266 (ECC, Reg). $190.
• Chassis? I like SuperMicro's 942i-600 chassis. Hot swap fans, and a 600W N+1 power supply (Three 300W modules). $550. $35 extra if we want a rackmount kit.
• A SuperMicro SCA SATA mobile rack, which gives us a 5-drive capacity for our array. $135.
• RAID? Not too sure how the host controllers for SATA work. But 3Ware's 8006-2 looks sufficient, at least for our mobile racks. We'll need two -- one for the arrays, and one for our system drives. $135 each.
• Floppy? Mitsumi is fine to me. $10.
• Optical? Some DVD-ROM/CDRW. $50.-----So before drives, and including the rackmount kit, we are at $1750. No need for a keyboard or mouse, because I assume this would be hooked into an existing KVM.System drives? $220 for two WD 36G raptors. Granted they're $20 more each than some 80GB 7200rpm drives, but a 5 year warranty is nice, and we don't need much space on these drives anyhow. Mirror these.
• Need hotswap bays for our Raptors. Figure $40 each.So at $2050, eh?Five Maxtor or WD 250GB drives, which we'll run in RAID5. About $1250-$1300. These both have 3 year warranties, so just get what performs better.-----
• Total? $3300 for 1TB of fault tolerant storage.

What advantage do we have over FiringSquad? Our NICs can be load-balanced. Our fans are hotswappable. Our power supplies are hotswappable. All of our disks are hotswappable. We can add a 2nd CPU if we assigned different duties to our server that merited it (reassigned duty to a DB server). We can add TONS of memory if need be. (up to 16GB).If we wanted to add another TB of storage, we'd add 5 more drives, another mobile rack (we have room for one more ), and another controller. So another TB of storage would be about $1500.1TB that's going to hold up better under fire for $200 more than firing squad, and we can boost it to 2TB and still be under $5K.

Building a SATA Terabyte Server

My company needed an application server that could run Ghost and also storte the images. We estimated that a terabyte would be sufficient for a few years. It seems that prebuilt machines come in two varieties, application servers and storage servers. Application servers use SCSI drives and won't have enough storage and application servers either run Linux, embedded linux or MS Windows Storage Server that will not run Ghost. Dell came the closest to creating what I wanted but they insisted that the system drive be part of the RAID. I felt that was not wise because I want the system to work even if one of the five hard drive fails. I wanted a brand name so I did not go with J&N though it might have been a better idea. Inspired by artcles like Build a large, cheap Linux file-server, Building A Budget Storage Server/Workstation and two terabyte file server, $3100; I have decided to try building one from parts.

• Seagate Barracuda 7200.7 Hard Drive
• Tyan Trinity GC-SL (S2707GNN-533) ATX Motherboard
• SimpleTech 512MB Module (2)
• Antec 120mm SmartCool 120 MM CASE FAN
• Antec Performance One P160 - mid tower - ATX
• 3Ware Half Length/Full Height, SATA RAID Controller, 8 Port 9500S-8
• Intel Pentium 4 2.8 GHz processor
• LITE-ON SOHR-5238S 52x32x52x CD-RW Drive
• Maxtor MaXLine III - hard drive - 300 GB - SATA-150 (5)
• StarTech.com ATXPOW450PRO 450 Watt Power Supply

My plan is to use the Seagate drive as the system drive and the Maxtor drives for a RAID5. I ordered through CDW and not all the parts have arrived.

I chose the case for three reasons:

1. It could hold 10 drives.
2. It was Antec's top of the line case
3. It did not come with a power supply and I wanted a supply that was warranteed for commercial use. I would have preferrred a PSU from Pwer and cooling but CDW does not sell them.

The cons of this case:

1. It is expensive
2. There are only 6 3.5 inch bays and one will be needed for the floppy drive so I will need to use an adapter kit to fit a hard drive in the 5 inch bay.
3. It looks like a home or gaming computer with LED's

A client got the following error message:
Autoexec.nt - The system file is not suitable for running MS-DOS and Microsoft Windows applications.
Solution either Autoexec.nt, Config.nt, or Command.com is either missing or corrupt and need to be replaced in the c:\windows\system32 folder.
