The default answer you would get from Citrix is to test to see if the application works from an Terminal Server Session. Have you confirmed that it works over an RDP connection to the server? If it doesn't work over RDP then the application may not support Terminal Services at all (which means it won't work under Citrix). If it works over RDP I would suggest you check event or application logs after a Citrix failure to see if there is an answer there (such as access denied errors, etc). You can also turn on process level logging to see security events not turned on by default.

I have a Delphi 7 application which uses a SOAP object to access the UK Government DPS Messaging Service. This has been running successfully at numerous clients sites for the last few years. Recently one of the clients moved to Citrix and is now gettting an access violation accessing the DPS Service. The error address is reported as $0115666D which is outside the scope of the application. This is built around the Delphi HTTPRIO object.<br />
<br />
I have no experience of Citrix so can anyone suggest any reasons why a web service that runs quite happily on Windows will not run on Citrix.<br />

Development in most programming languages is frequently done with an editor or integrated development environment (IDE). An IDE is a software application that provide comprehensive facilities to computer programmers for software development. An IDE normally consists of a source code editor, build automation tools and a debugger. XCode, Visual Studio, Adobe Dreamweaver and Eclipse are some of the more popular development tools, but an editor or IDE can be anything from simple text editors to sophisticated programs.
