Before anyone points out that this post may be in the wrong forum there has been a thread running for nearly 12 months now in the WHS Forum concerning greyed out clients in the WHS Console;
http://forum.avast.com/index.php?topic=41082.0It would be nice if someone from Alwil were able to respond rather than leave us all in the lurch...it seems rather cold down there in the forgotten forum...

The only official response was from vlk last January asking us to report back if we were still having the issue - since then the thread has grown to 4 pages of users with the same issue but absolutely no further response from Alwil whatsoever...

I did email support last December around the same time as the OP in that thread but received no reply...

Thanks & regards,
