Windows Vista

I am now also evaluating Windows Vista on my multimedia computer.  I performed the ugprade yesterday and it actually worked unlike my first upgrade attempt a few weeks earlier on a different home PC.  So far its not bad, but I think I need to reload a fresh install, as some weird issues are happening, such as the games not loading when you open the shortcuts for them.  One weird thing too is that hibernate works on my multimedia PC, but not on the home PC.  I guess there is some kind of hardware difference, perhaps something on the other motherboard that prevents hibernate from working.  So far I like having Vista, it runs ok on my hardware and I haven’t had any incompatibility issues.  It does take a little getting used to and most people don’t like change, but I don’t have much trouble picking up changes in software.

New power supply

For Christmas this year I got a new 600W Power supply for my main computer at home.  It’s so much better than the other one and makes much less noise.  There is also no more ripple sound effect that the previous one had.  I did however take the old power supply and rig it into my multimedia computer as the power supply I had for it was malfunctioning.  So now both computers have the juice they need and are working good. 

Exchange diagnosis

Symptoms

Server: Event ID 9646 (user exceeded maximum of 32 objects of the type session).  Event ID 1021 (unable to connect…error 0x4de)

Client/Outlook: Unable to open your default e-mail folders.  The Microsoft Exchange server computer is not available.  Either there are network problems or the Microsoft Exchange server computer is down for maintenance.  OWA would work ok when logged on as either the user or an Exchange admin account. 

Diagnosis:

   Google searches of the events and error messages yield very little help.  A second round of google searching and pressing further through the search results yielded a page from MS indicating to ensure that the user had “view information store status” rights granted at the server or mailbox store level. This lead me to a diagnosis of permission problems on the mailbox.

   Proceeded with treatment by administering re-application of full mailbox permissions for the user and ensuring “view information store status” was selected in the allow column.  Attempting to open outlook again immediately after still yielded errors as described in the symptoms.  It wasn’t until a few minutes later when about to attempt a different method of treatment that the solution was revealed.  Before trying to create a whole new information store and move the user for testing, I decided to open outlook again.  This time, it opened no problem and did not give any errors or show any signs of a problem.  Apparently the original solution was the correct solution and the treatment was correct, I just didn’t wait long enough for the change to take effect.  Further attempts to work on the problem would have been useless as the issues was already fixed, I just didn’t know it yet. 

Windows Vista Upgrade failed

Last night I was trying to upgrade to Windows Vista on my main XP computer.  I was 3/4 of the way through the installer when the install screen vanished and dropped me back to the XP desktop.  XP still seemed to work, and no matter what I tried, I could not get the installer to resume.  I had no choice but to reboot, but what I didn’t know was that Vista had already copied over its boot files and screwed with the MBR on my hard drive.  So upon reboot, I get a Vista boot loader, which goes to the setup screen, but promptly throws up an error saying (not exactly sure of wording) “Windows could not initialize the installer”.  So XP was dead at this point, sure there are some ways I could have gotten it back, but I really wanted Vista to install. 

I ended up using a Knoppix 4 bootable CD and using the file managers in linux to backup my data on my XP parition to a file share on a server in my network.  After the backup was done, I wiped the partition and loaded the full install of Vista and installed fresh on the clean XP partition.  I am not sure if I am going to go with Vista or not, so I’m installing from the media with no CD key, just to use it in eval mode.  If Liz likes it and can get used to it, we might go ahead and buy the Ultimate edition upgrade.  But for now we’ll give it a try and see how it goes.  So far its running great on my hardware, but I’m a little disappointed with the performance rating of 3.7.  I have a dual core P4 3GHz chip, 2 GB of performance DDR2 RAM, and 256MB ATI X600 PCIe video card running on a nice Abit motherboard.  I was expecting to get a score near or at a 5. 

at&t HTC 8525 phone buttons not working

Recently saw an issue where a user with an 8525 had problems with the phone buttons, where they would just stop working.  A little google search revealed that other people have had this issue, ROM version didn’t make any difference and it seemed to be sporadic.  This forum on the cingular website had a post by a user who said to slide open the keyboard, and loosen the screw on the back of the keyboard closest to the navigation buttons.  I initially completely overlooked the word “loosen” and asked the user to tigten the screws on the back.  After this was done, the phone buttons worked perfectly.  Then I re-read the forum post and realized the recommendation was to actually loosen the screws.  I don’t personally buy the overheating explanation, but slightly tightening the screws resolved it for us this time. 

NoSpamToday – SPAMLOGS missing subject fix

Over the weekend I got an e-mail from Dennis Heidner who wrote SPAMLOGS for NoSpamToday.  In version 3 of NST, the log parser “spamlogs” quit outputting the subject line of messages in the parsed log output.  Dennis has corrected this in an updated version which should be available soon on the byteplant contributions area on their website.  I have tested the new version and found that it fixes the problem.  Dennis has also added some functionality to check for AUTH Attacks.  SPAMLOGS conveniently checks for AUTH attacks and outputs the number of attacks per IP at the end (last column) of the spamlogs csv output. 

SPAMLOGS is a must have for parsing the NST spamassassin log file, it turns the jumbled and confusing log file output from NST/SA into a readable and useful .CSV format.  Combine his software with the automation utility or scheduled task, and it makes managing the mail logs much easier. 

Radiator install complete

On the way home Friday evening, I stopped by the local Advance Auto store and picked up some anti-freeze fluid for my new radiator.  I was also going to get new radiator hoses, but they don’t carry the hoses I would need for my Miata.  So I just got some shop towels and the anti-freeze.  Then I ran to sweetbay and picked up some distilled water to mix with the anti-freeze. 

When I got home, I got started right away on my task of replacing my radiator.  It took me a while to get started, as I was trying to figure out how to get access to everything I needed to get to.  At one point I thought I’d have to take off the cover under the engine compartment to get to the bottom of the radiator, but fortunatly I managed to give up on that and was able to do my job without having to remove the cover.  Getting the old radiator out took me the longest time, as I had some trouble with the lower hose which seemed stuck.  I finally got all the hoses and bolts and connections off the old radiator and pulled it out.  I installed the fans on the new radiator and then dropped it in fairly easily.  Then re-connecting a few hoses and wires and I was off and running.  I ended up doing a 50/50 mix of anti-freeze and water, but only by accident.  I read online that the miata radiator takes 6.7L of liquid, so I got three gallons of distilled water and a single gallon of anti-freeze.  I got way too much fluid and ended up not even using a whole gallon of each type of liquid. 

I took the car out for a spin and made sure there were no flow problems or overheating issues.  Everything works great and it was a much easier job than I thought it would be.
