[Samba] Domain not available even minutes after workstation startup

[Abe Lau]

Just an update, disabling media sensing (fix to 100Mb full duplex) seems to
do the trick!

Interestingly, those with gigabit connection seems to work now (at least for
last few days) even with auto-sensing enabled... really not sure why.  I
hope that is going to last.

thx Gaiseric
