First of all an HP LANALYZER would be able to measure network load, also if you running token-ring the netmain tools provide some useful info. Chances are with only 10 node the network is not the problem. Most of the slowness is probably do to the X interface with the old domain operating systems. I would recommend upgrading to 10.3 ASAP. -- Rick Scalera #include "BNR does not share my opinions. I wouldn't be an MSS if it did"
