Good afternoon, We're running an XPe SP2/FR2 farm. Our Windows 2000 domain is in Mixed mode and all ADC servers are running Windows 2000 SP3. Our Citrix servers are each configured with 2 network adapters on the same subnet and all the adapters are configured for 100Mb Full Duplex. Our users connect to our published apps through CPN. Several users have started recieving the following error when they start an application from PN: Not able to find ICA connection settings The connection cannot be launched." The application icons then disappear from PN. When our users refresh their published apps they will then recieve this error: "There are no applications available for the supplied credentials in the current Application Set." This means that our users have to refresh their published apps until they receive new icons for their apps whereby they can connect to the published apps as usual. I've also noticed that I recieve the second error at the same time that our users receive the first error so they are definetly related. Restarting the IMA service or rebooting the Citrix servers doesn't help. These servers have been running for 1 year without any sign of this problem. This problem began today and I know of no changes anywhere on our system and haven't received any sign of network problems. Any advice will be greatly appreciated Regards, Robert Armstrong <mailto:robert.armstrong@xxxxxxxxxxxxx> This message may contain confidential and/or privileged information.
