The particular svchost.exe in question is hosting the Remote Desktop Services service. This is only happening on one of my XA 6 servers. The rest of them appear to be running fine. When this happens, the server becomes literally unusable. Nobody can login and those who are logged in can't do anything. I read in the Citrix forums that hotfix rollup pack XA600W2K8R2X64R01 might address this.
Just wanted to see if anyone else has seen this and how you fixed it? As always thanks in advance.
