Extract RAR Files

Downloaded and installed Free RAR Extract Frog to extract a file in the RAR format.  Nice, clean, small program.

Identifiying blocked sites

Downloaded and installed MS Network Monitor 3.4 to identify what web site was being blocked for glogster.com, causing pages to not fully load (flash animations would not load, had a spinning pink donut).

Network monitor was able to show what traffic was going across Internet Explorer on my PC, then I could identify which site was blocked.

Network monitor download file was NM34_x86.exe, also has versions for Windows 7 and 64 bit.

MS Outlook Hidden Folder

Downloaded and installed an application from MS to edit the MS Exchange settings.  Program name is MFCMapi.exe.   Looks like a handy tool for tweaking Outlook settings stored with MS Exchange.  Download file name was MFCMapi.exe.6.0.0.1024.zip

 Run it with Outlook open, the click on “Session\Logon and Display Store Table”, select the applicable profile name,  double click on the desired entry under “Display Name” , expand Root, expand IPM_SUBTREE, select the desired folder,  double click on PTR_ATTR_HIDDEN, and finally uncheck the “boolean” checkbox to un-hide the folder.

Did this to unhide KW’s “Inbox” folder in Outlook 2010 yesterday.

Slow Running HDDs on Laptops

Found that HDDs were running in PIO mode instead of DMA (or Ultra DMA).  Check this in device manager under IDE, primary device.  It will say run in DMA mode if available, and then show currently running in PIO mode, if this is the issue.  Ran “HD Tune” program to verify drive performance issues.

Ran a Visual Basic script to reset the registry settings to force WinXP back to DMA mode on the drive.  DMA mode causes the PC to go through the Disk Management processor.  In PIO mode disk access goes through the CPU, causing slow performance and heavy CPU usage (90-100% usage).

Ran this on both Teresa P’s and Amanda K’s Dell D610s.  Teresa’s was back to PIO a few days later.  Amanda opted for a different laptop.  Have seen this on a few others and generally recommend that the user back up all files, and prepare for possible HDD failure.

Script name is resetdma.vbs
