I have read quite a few posts about how MS Homegroups seem to encounter problems when used on computers with McAfee Total Protection; it came pre-installed on my Dell desktop. My laptop has F-Secure provided by my IP - both have W7 Home Premium installed. I set up an MS Homegroup without issue and both laptop and desktop see each other on initial bootup with folders kept in sync using MS Live Mesh and MS Outlook, synced using Sync 2. However, after a few minutes they lose the connection, unless I manually sync folders and Outlook every 5-10 minutes. Once connection is lost then the only way to re-establish connection is to re-boot the desktop, suggesting to me that McAfee is the culprit. Has anyone else come across a similar issue and, if so, did you manage to solve the cause?
