homegroup windows 7 64bit sometimes loses connection.

[akirarulez]

Since a while (a day i think), my htpc keeps losing connection with the shared folders on my main computer.
Both are Windows 7 machines (64bit) and both have updated nic drivers.

They can see eachother. But after a while the connection between the 2 just stops. making XBMC just stop playing and doing nothing as it tries to connect to the file again.

Steps made so far:

• Both networks cards manually set on 1Gbps and 100Mbs Full Duplex: No difference
• Several Energy related settings disabled: No difference
• Alot of restarts :D : No difference
• Changed folders on my mian machine, reshared: No difference

Note that this is a new problem. Been using my htpc happily since i build it.
Any ideas where i should look?

Sometimes I get a strange problem with my router not connecting properly with wireless devices and shared folders can be an issue. Rebooting the router often fixes it so I would start there first.

I should add both are wired and router has been restarted a few times to exclude that.

Static IPs and DNS?

Main computer is static (network wise :P), changing it on the htpc too now.
