    Converting WMA to MP3 on Mac

    As most on you know I recently purchased a Mac and I must say I am very pleased.  Being a big Linux enthusiast I am very pleased with my new Macbook pro the look and feel is great and the easy user interface is great.  The Mac really reminds me of the current release of Ubuntu just better.  Sorry to all you Ubuntu users I am not trying to offend anyone but that’s my feeling anyway.  I still like Linux so you will still see me at the Linux conferences just with my Mac.  But one thing I did struggle with most of my music was in WMA format.  On the Mac only MP3 and up gets recognized.  So I used this tool All2MP3 to convert my library.  I was very pleased everything converted no file corruption or anything.  All you have to do is install the tool.   Just click the add button pick the files you want to convert.  Click convert and the software does the conversion very fast and painless and drops the MP3 in the original folder with the WMA file.  The link be low will allow you to download the app and has a few instructions. http://www.techzilo.com/convert-wma-to-mp3-mac/

    Fix Missing or Corrupt Hal.dll

    Boot to the Windows recovery console get to the proper drive (usually is c:) type attrib -H c:boot.ini enter type attrib -R c:boot.ini enter type attrib -S c:boot.ini enter type del c:boot.ini enter (you are deleting the boot.ini this is normally the reason for the corrupt hal.dll) type bootcfg /rebuild fixboot After the fix runs reboot and everything should be fixed.  When I first did this I ran into an issue where I got an error “can fixboot on a corrupt registry”  I ran and chkdsk /r after that completed I ran step 7 again and everything worked fine. I have also heard an alternative solution fix this issue in the recovery console do the following command Expand D:I386HAL.DL_ c:WINDOWSSYSTEM32HAL.DLL I have never tried this method so I cannot prove it works  but if your issue persists it might be worth a try.  If you get an “access denied” do the attrib command to the HAL.DLL file that might help you. Again I have not tried this method just giving suggestions.
  • A friend of mine passed this a long and since I have not had a security post in a while and this is a great article I thought it was worth posting.  Talks about how certain devices on the network like printers, fax machines and security cameras exc are over looked in vulnerability testing.  The article also hits on some other errors in vulnerability testing. http://www.darkreading.com/vulnerability_management/security/perimeter/showArticle.jhtml?articleID=225700674

    Windows DNS Aging and Scavenging

      Had a big DNS problem today and this article really helped me out very detailed and easy to understand.  I have worked with DHCP and DNS in the past never realized how many setting and options there really were to set.  Was interesting you would ping a PC by name and would come back with the wrong IP.  The problem ended up being a combination of short DHCP leases with a long aging and scavenging time set in DNS. http://searchwindowsserver.techtarget.com/tip/0,289483,sid68_gci1040355,00.html
  • I recently worded on an issue where you would import computers into an imaging collection and it would take hours before they would kick off to image.  I found a Microsoft Hotfix to fix this issue.  Microsoft hotfixKB980270 took care of this issue for me I applied the patch rebooted the server and everything we imported starting imaging.  This issue focus on System Center Configuration Manager 2007 Service Pack 2 AKA SCCM 2007 SP2 but I can tell you from experience SP1 also had the same issue and there was a separate hotfix to fix that issue. http://support.microsoft.com/?kbid=980270

    Setup SCCM PXE Point

    There have been many posts out there trying to address the issue behind Native Mode and PXE and/or Boot Media problems. This posting publishes information I found in the following article and additions which I have made to clarify some certificate configurations. Step 1 In the site properties , check that you have imported your Root CA certificates. If you have subordinate CA servers , import them as well as I have seen issues arriving when not importing them .The picture below will give you the idea : Step 2 Create your OSD PXE service point Certificate & export it . Go to your certificate authority and duplicate the Computer certificate , name it Configmgr OSD certificate and make sure that you could export the private key ! My Comments: MAKE SURE SUBJECT NAME TAB CONTAINS: SUPPLY IN REQUEST. When the request is made, give the certificate the following Attributes: • CommonName: (i.e. OSDpxeBootCert..Com) • Alternate name: OSDpxeBootCert..com • Friendly name: Any descriptive name. Note: Because certificates are Required through out the native mode deployment. FQDNs are also required for certificate Subject name and Alt Subject Names. When you have created the certificate , export it to a DER format by going to MMC – Certificates – personal – Request new certificate . Select the Configmgr OSD certificate and install it on your machine . When done , right click on the certificate and select export . Export the certificate with private key and when exported , delete the certificate you have requested . Step 3 Import you in the PXE role configuration pane . Now we go to the SCCM console and go to Site systems – PXE Role , import the certificate you just exported . The picture below explains it : You will get the following warning when you exported the certificate on the Site server itself . This is...
