Kurt, Here is what I would try in order of likely resolution: 1. try changing the URL for the web reference to use an IP address to the web server instead of a server name. 2. disable any firewalls on the Windows 2000 machine the device is attached to Darren Shaffer Chief Software Architect Connected Innovation Microsoft Device Development MVP darrens@xxxxxxxxxxxxxxxxxxxxxxx _____ From: comodev-bounce@xxxxxxxxxxxxx [mailto:comodev-bounce@xxxxxxxxxxxxx] On Behalf Of Kurt Halvorson Sent: Friday, February 09, 2007 11:50 AM To: comodev@xxxxxxxxxxxxx Subject: [CoMoDev] A difficult problem, any ideas? I hope life is treating everyone good. Life is good up here in Fort Collins, other than my annoying problem below: I have a PDA running WM5 using CF 2.0, written in VS2005. SQL Mobile (or whatever it is currently called is installed) My application connects to a Web Service (running on an out of state server) to upload and download data. The Web Service was added to the application using "Add Web Reference" in the solution explorer. wrServiceMain is the name of the added reference. It just returns a dataset of needed information. Here is a snippet of the code: Try Dim wsUsers As wrServiceMain.Service = New wrServiceMain.Service ds = wsUsers.GI(xxxxxx) Catch ex As Net.WebException The PDA App can upload/download data under the following conditions: - Running in the emulator - Cradled on my Work PC using ActiveSync 4.2 (Windows XP) - Cradled on my Home PC using ActiveSync 4.1 (Windows XP) - Free internet hotspot at local coffee shop via Wireless - Surf the web normally on all above situations My client is running Windows 2000 at a large Utility. He had to get IT to install ActiveSync 4.1 When calling the above code the exception ex.Message is "WebException" On the PDA, in the cradle he can surf the internet using IE. The App works as expected at the local hotspot. It seems like a problem on his end, but as expected, solving the problem falls on my shoulders. I've spent close to two days on this problem, any ideas? Kurt
