OK here is my problem. We have received complaints from clients that they get I/O errors when trying to connect to applications threw the ICA Client 6.31(Windows 2000 SP3 XP FR2 backend). The immediate fix is for them to just hit refresh. The ICA Client then asks them to authenticate again and the applications work fine. Easy fix yes, but we are about to upgrade the rest of our corporation and want to prevent this problem. Does anyone know what may be causing the client to lose its authentication? I can not duplicate this problem on my workstation.
