At work, people were using VPN to access their email out of the office, but I have always thought that logging into a corporate network via VPN for most users is an extra hassle that they could probably do without. I had considered setting up RPC over HTTPS for Exchange 2003 but during a meeting regarding disaster recovery it became evident it was actually now a necessity. So, after configuring the server for RPC-HTTPS I had the small problem of deploying the settings to Outlook clients en masse.
Post the upgrade of a VMware infrastructure from ESX 3.5 to vSphere 4, I encountered an issue when upgrading the Virtual Machines. I had already installed the latest VMware tools and after upgrading the hardware from version 4 to version 7 I wanted to remove the standard NIC attached to each Virtual Machine and attach the new vmxnet3 NIC.
