    My thanks to Mr. Follmann and all you others that helped.
As it turned out ATT's router having an address of 192.168.1.254 is
not immutable but subject to change by the user(me). Setting ATT's
router to 192.168.2.254 solved all my problems. With eth0 and eth1
both up, the  Linux box and the Win2K box can both browse the i'net
passing GRC.com's all ports scan and I can still mount the Win2K
shared partitions from Linux.
    An extra thanks to you, Henning for pointing out the trouble spot.
