Have a client that is running a Windows 2008 R2 RDS server that has between 8-10 active users. The server is a virtual machine running on a 2008 Hyper V server. The users report that the system will become unresponsive for them at various times. We have not been able to track down any one source to be able to replicate it. I added an additional Virtual CPU to the system and that seemed to help. Shortly after it happened the last time I connected to the 2008 R2 server and noticed that there was high CPU usage from both Firefox and Microsoft Publisher 2003. I did not install Office 2003 or Publisher 2003 on this server. My memory says that there were some special directions for installing Office on to 2003 Terminal Servers but I'm not sure about 2008. Also don't even know if Office/Publisher 2003 is compatible with 2008 R2 RDS. Finally it seems that they run Firefox, Google Chrome, and IE on that server as each user has their own preference. Has anyone else seen issue with allowing all 3 browsers to be used?
