Hi Guys, I've been having problems with Windows Update and Set Up on SVR2008R2 and WHS 'Vail' in Hyper-V. If I use a Hyper-V 'Network Adaptor' Windows Update almost always error's out in SVR2008R2 and Vail won't update or allow me to setup a Domain. Lucky, switching to a Hyper-V 'Legacy Network Adaptor' solves all these problems. Has anyone else had any problems like this. I'm using SVR2008R2 Ent. with Hyper-V, on a Dell Dimension 9200. Activated with the Ent. SLP key, Dell SLIC and Cert. This happens with the builtin Intel NIC, a NetGear GA311 and a D-Link DGE-528T. So my guess is, its some sort of bug in the Virtual Network driver.
