Hi All, We have recently been rolling out new win7 desktops with a new version of receiver but only as far as 3.1 enterprise (tested 3.2 same issue), and our Xenapp environment is 6.0 Win2008R2. However we are seeing just a few users having issues with apps disconnecting from xenapp when their PCs goto sleep. I have changed power settings on PCs for PC and for the NIC so the HardDisk and NIC do not go to sleep, however we are still seeing these few users having the same issues. My next step is to look at BIOS power settings but was wondering if anyone else has seen anything similar when upgrading from citrix client 12.x to receiver 13.x, any other ideas that I might of missed?
