There are 3 PCs at home, 2 (not identical) Sony laptops and a self-built tower, all running Win7 home premium. The laptops were bought with Vista (not then current so money off) and an upgrade from Sony was applied to both; the tower had a clean install.
Although all were on the homegroup, one laptop could not access files on the other PCs. They could read and write to it, so there was a way round the issue, so it wasn't a disaster that I couldn't solve it.
Some other issues arose with the uncommunicative laptop so I put in a fresh install (rather than Vista plus upgrade) and now it won't even join the homegroup. The error just states that it cannot join, and the troubleshooter finds nothing (surprise!).
The other 2 PCs were removed from the homegroup, rebooted and a new homegroup started from the problem laptop. This, and every setting check or change I can find in forum entries on similar problems, has not fixed the issue.
Event viewer came up with unhelpful entries of
[ul]
[li]source: atikmdag, CPLIB:: General - Invalid Parameter[/li]
[li]source: atikmdag, Display is not active[/li]
[li]source: service control manager, the Update Jump Flip service failed to start due to the following error: the system cannot find the file specified.[/li]
[/ul]
Other things checked included - registry entries for homegroup networks; firewall has homegroup rules but tried turning it off too; IPv6 is enabled. Also ensured all following services started: HomeGroup Listener, HomeGroup Provider, Peer Name Resolution Protocol, Peer Networking Grouping and Peer Networking Identity Manager.
If anyone has any idea what's going wrong I'll be mighty grateful.
