tried your setup on my end, pt dual port with win7 ultimate 64bit, created static link aggregation team then connect to linksys switch, verified both ports are in "active" state, set the system to sleep mode. once the system is back, the ports remain to be in "active" and doesn't exhibit the problem you have, what is your teaming driver and NIC driver? i'm using 9.8 (team) and 9.1(adapter), i got them from the latest 16.4 package.
Thanks for the info, sage99. I'm using W7 Ultimate SP1 64bit plus driver package 16.4.
And yes, you are right, with Static Link Aggregation it seems to work, this is amazing for me..., thanks.
As opposed to your approach I used Dynamic Link Aggregation with lacp (IEEE802.3ad). This setup shows the behavior I described. This cannot be a problem with the dlink switch, because two Netgear switches and a NAS are connected to it via LACP. I played around with Vista 32/64 and XP 32 and found that Vista 32/64bit shows the same (mis-)behaviour, but...WindowsXP SP3 works as expected (good old times)!
The bottom line is, that static link aggreation works for me, until someone fixes the LACP implementation...
Thanks again for your support.
