Previous reply did not go to list, so here it is again:

Hi,

My Win 100 machine stopped connecting to my NAS - after one of the=20
Windows updates. I could ping the NAS, just not connect to it. After a=20
quick sniff on the net, I disabled the IPv6 interface on the network=20
adapter, so forcing IPv4 for that interface. Happy as Larry now. My NAS=20
is old and does not support IPv6, and Windows was appearing to use it=20
instead of IPv4, as it had done previous to the update.

Hope it helps.

....Andy
