Thanks to all who responded, Jeff Hummel, Scott Ruffner, Rob Sloane,
Selden Ball and Paul LaMadeleine.
All of them suggested to check the settings on the NIC card and compare
it to the settings for its port on the switch, which I did, found out
that the switch was set to 100/Full while my systems NIC were set to
100/half.
Since I couldn't set the system's NIC to 100/Full without getting the
NIC down, I have asked the network guy to set the ports on the switch
to 100/Half till next down time.
Thanx to all
MKMA
