I am having some Citrix servers grey screening (can ping but cannot RDP) and have to be power cycled to get them working again.
I have created an alert based on the ImaSrv.exe service which helps, but this process can be down but the server is working fine, subsequently, I get a false positive.
I need to alert on a Windows service that can ID a true grey screened server.
I hope this makes sense. This does not happen on NON-Citrix servers.
