Our Citrix server locks up on a fairly regular basis, when it does it kicks everyone out and the only way to get back in is to perform a hard boot of the sever. What is happening is the server is stopping ICA, RDP, and local access to it. It is not going fully down. It is still responding to pings while it is in this state. I have contacted Citrix on this and they have been very slow in getting back to us. Does anyone have any suggestions? I have installed all of the Citrix Hotfixes for this box and the recommended MS ones as well.
