Understood. I did not create a Homegroup on the desktop, so at this point I have zero Homegroups. I did try to create one from the desktop after the one from the laptop failed, but it fails with the same message, weird. On the desktop I just have the LAN connection, that is setup as a Home network. The laptop has a LAN connection, but it has been disabled, only the wireless card is active as far as network connections go. Looks like I may have to reload both. I renamed the workgroup, I'm beginning to think there may be a bug that is related to changing the workgroup name and Homegroups.
