VERY SLOW LINK WITH THE SERVER

I HAVE A NETWORK OF WINDOWS 98 SE CLIENTS AND A WIN 2003
SERVER.

ALL COMPUTERS ACCESS THE SERVER WITH NO PROBLEM EXCEPT
THE MOST MODERN ONE (PENTIUM 4), WHICH HAS MORE MEMORY
AND MORE PROCESSOR SPEEED, HAS FASTER ACCESS TO THE
INTERNET BUT SURPRISINGLY A VERY SLOW ACCESS TO THE
SERVER.

ALL COMPUTERS HAVE THE SAME ETHERNET CARD AND THE SAME
WIN 98 SE SOFTWARE.

THANK YOU
