If you are having data connectivity issues on the MTS network this web site will show you the status of their services. Useful to figure out whether it's systemic or just you (or your customer).
I recently installed a Dell Server by using the Lifecycle Controller. This system uses a wizard to help with the installation of the operating system. In this case, I was installing Windows Server 2008 R2 to replace an existing Exchange 2010 server. As part of the installation, an OEMDRV USB drive is created by the Lifecycle Controller that contains the drivers used during OS installation. OS installation went well, but I ran into an issue afterwards. The OEMDRV drive was using E:, which I needed for my Exchange data. When you go into computer management, OEMDRV shows as a removable drive. However, you cannot change the drive letter or eject OEMDRV. By default the Lifecycle controller removes this drive after 18 hours, but I didn't want to wait that long. To force OEMDRV to be removed earlier, restart the server and press F10 to enter the Lifecycle Controller configuration. Then exit the Lifecycle Controller and reboot again. You don't need to make any changes in the configurat...
Windows 7 has a nifty new feature called XP mode that uses Windows Virtual PC in the background. My first surprise is that I had to download the software for this from MS which was about 500GB. However, that was the least of my worries. It turns out that Windows Virtual PC will only run with hardware assisted virtualization. On AMD processor systems this isn't an issue because almost all AMD processors have hardware assisted virtualization. Intel, on the other hand, has been using hardware assisted virtualization as a differentiator between upper and lower end chips for the last several years. Basically trying to get a premium out of it. Many computers with Intel processors do not have hardware assisted virtualization. Unfortunately, my laptop is one of these. Fortunately, even though it is unsupported (like I'd be calling for support) Virtual PC does run on Windows 7. A blog documenting it is here: http://blogs.msdn.com/virtual_pc_guy/archive/2009/08/19/running-virtual-pc-2007...
Older versions of Microsoft Exchange in a hybrid configuration with Exchange Online (EXO) used a federation trust to authenticate connections for free/busy information. Newer hybrid deployments of Exchange 2016/2019 use OAuth authentication instead of federation. OAuth authentication is reliant on the Auth certificate in your on-premises Exchange. This certificate is created automatically with a lifetime of 5 years when you install Exchange Server on-premises. If this certificate has been replaced, then you also need to update Azure AD with the new certificate information. The simplest way to update the information is by running the hybrid wizard again after you update the Auth certificate. I wrote a previous post about renewing/updating the Exchange Server Auth certificate here: http://byronwright.blogspot.com/2018/05/expired-microsoft-exchange-server-auth.html If you update the Exchange Server Auth certificate and forget to update the information in Azure AD, you are likely to see fr...
