In the past when I have seen this on our older Wyse units, it was a DHCP problem where the thin client was not getting an IP address. ________________________________ From: thin-bounce@xxxxxxxxxxxxx [mailto:thin-bounce@xxxxxxxxxxxxx] On Behalf Of Luchette, Jon Sent: Monday, June 13, 2005 9:19 AM To: thin@xxxxxxxxxxxxx Subject: [THIN] Re: WYSE "Protocol Driver Error" it occurs when these units are in the process of making a connection to the published desktop, it is not every time but it is happening more and more often. they disconnect after an idle timeout of 2 hours, and then they are setup on the terminal to auto start the connection. so it is after they logoff, when they start to make the connection to the published desktop that they get this error message. usually just a plain old reboot on the terminal will clear the error message temporarily. _______________________________________________ Jon Luchette Emerson Hospital Technology Specialist III Work: 978-287-3369 Cell: 978-360-1379 jluchette@xxxxxxxxxxxxxxx _______________________________________________ ________________________________ From: thin-bounce@xxxxxxxxxxxxx [mailto:thin-bounce@xxxxxxxxxxxxx] On Behalf Of Jeff Durbin Sent: Monday, June 13, 2005 9:07 AM To: thin@xxxxxxxxxxxxx Subject: [THIN] Re: WYSE "Protocol Driver Error" When does the message occur? If it's at startup, maybe it's a speed/duplex negotiation issue. ________________________________ From: thin-bounce@xxxxxxxxxxxxx [mailto:thin-bounce@xxxxxxxxxxxxx] On Behalf Of Luchette, Jon Sent: Monday, June 13, 2005 5:54 AM To: thin@xxxxxxxxxxxxx Subject: [THIN] WYSE "Protocol Driver Error" Hello, We have been having an issue for quite some time now with our WYSE thin clients getting this "Protocol Driver Error" message far too often. All that WYSE has come up with to troubleshoot is to try and reset the terminal to factory defaults to clear out the flash and see if it happens again, but that is not working at all. When these units get this error message, they are not pingable on the network. They are running CE.net 4.2, and we are running MF PS 3.0, on 6 win 2k sp4 servers, dual PIII procs, w/ 4 GB Ram. These clients automatically logon to a locked down Published Desktop. Has anyone else seen this Protocol Driver Error message on WYSE thin clients before and come up with a real fix? Thanks, _______________________________________________ Jon Luchette Emerson Hospital Technology Specialist III Work: 978-287-3369 Cell: 978-360-1379 jluchette@xxxxxxxxxxxxxxx _______________________________________________
