Sounds like it could be a problem with your NIC card \ drivers. Are you running 10 \ half on the nic and 100 \ full on the switch? or 10 \ half and auto \ auto? Try running 100 \full on both. Make sure NIC's are firmwared and driver'ed up (new term there....) Check WINS \ DNS \ SNM \ GW settings to ensure consistency. You stated that only some users have this problem...elaborate more here. Do you have 20 sites and only 1 site has this problem? Is it intermittent across all sites? If all are fine and 1 site sometimes has this error amongst various PC's at that particular site then I'd say that it's definately something in their LAN. Maybe try switching out the router \ switch \ hub, check any firewalls, routing tables, etc... -----Original Message----- From: thin-bounce@xxxxxxxxxxxxx [mailto:thin-bounce@xxxxxxxxxxxxx]On Behalf Of jc lamb Sent: Thursday, February 19, 2004 6:24 PM To: thin@xxxxxxxxxxxxx Subject: [THIN] (resent) users dropped with Protocol Driver Error - after 3 minutes fo connection Resent due to no responses. we are lost on this one.
