SBS 2011 and .NET Framework 1.1

By brendon on February 6th, 2012

<sigh> New SBS 2011 Essentials server and customer just HAS to install QuickBooks with .NET 1.1 </sigh>

Thanks to several posts on the SBS Diva Blog I was able to identify the issue and fix it in a slightly different way.

All web sites hosted (http://server/Remote, /Connect, etc.) were reporting the following HTTP 500.0 server error -
“Calling LoadLibraryEx on ISAPI filter “C:\Windows\Microsoft.NET\Framework\v4.0.30319\\aspnet_filter.dll”

Is obviously caused by x64 code being executed by x32 .NET – Enabling x32 compatibility in the Application Pool did not help. To resolve: Continue Reading

My certificate is missing it’s public key….

By brendon on November 3rd, 2011

Ever had a problem where you KNOW the certificate private key is on the server but the certmgr says otherwise??

I Found a really usefull post which shows how to fix Just this issue!

Option #1:Repair Damaged Certificate (Windows Server 2003/2008)

    1. Open MMC and add the Certificate Snap-In for the Local Computer account.
    2. Double-Click on the recently imported certificate
    3. Select the Details tab.
    4. Click on the Serial Number field and copy that string
    5. Open up a command prompt session. (cmd.exe aka DOS Prompt)
    6. Type: certutil -repairstore my “SerialNumber” (SerialNumber is that which was copied down in step 4.)
    7. After running the above command, go back to the MMC and Right-Click Certificates and select Refresh (or hit F5 in the MMC)
    8. Double-Click on the problem certificate. At the bottom of this window (General tab) it should state: “You have a private key that corresponds to this certificate.

30 seconds later – Legend!

Just keep in mind, SBS likes to have any certificates with a subordinate authority also have their certificates listed in the MMC -> Certificates -> Server -> Trusted Subordinate Authorities.

Hyper-V Session Notes

By brendon on July 30th, 2010

I recently did some free M$ run training on the Hyper-V R2 & System Centre VMM. Good and interesting, I can definitely see this being useful for a number of our smaller deployments. Small things put MS ahead of VMWare I see are:

  • Support for USB monitoring of UPS / USB Backup Disks pass through.
  • Built-in support for existing AD authentication, no special ‘root’ passwords for individual ESX hosts.
  • Group Policy Support.
  • Time based power management policy for Hyper-V hosts. (Low power after hours).
  • FREE Hyper-V R2 version of 2008 server. Downloadable direct from Microsoft.
  • Host updates can be done using existing WSUS server.

Keeping all this in mind, I still see VMWare vSphere as the king of the data centre. I just think (similar to Terminal Services and CITRIX) Microsoft will catch up over the next few years.

My notes from the sessions are here: Continue Reading
