Is DNS properly configured on the devices, or more importantly, the server location for the ICA session configuration? Try changing server location to a static IP address instead of DNS Name and port, presuming that you are using TCP/IP + HTTP to resolve the farm ZDC location. I have seen the timeout error on other Wyse devices when the device could not resolve the ZDC location through DNS misconfiguration. rob 24 Hour Fitness, Inc. ________________________________ From: thin-bounce@xxxxxxxxxxxxx [mailto:thin-bounce@xxxxxxxxxxxxx] On Behalf Of Schneider, Chad M Sent: Wednesday, May 17, 2006 12:29 PM To: thin@xxxxxxxxxxxxx Subject: [THIN] Wyse units We have 100+ Wyse 1125 Blazer units running in Wisconsin at several plants across the WAN. LOVE THEM! Sent one to Ohio plant and one to Indiana. The units at those sites, can only connect to apps. in one of our 3 farms, all of which are housed in Oshkosh, WI, in the same data center. Any ideas? Almost immediately, when connecting to an ICA application on the 2 non-working farms, get an error ICA-Connection Timed Out. Using RDP,. I can connect to servers in the same farms that don't work in ICA. Wyse is stumped. Chad Schneider Technology Analyst/Citrix Admin. Bemis Company, Inc. 920-303-7609
