Found another post but the fix doesn't appear to be available on Server 2008 R2. I have an exe file published in Citrix from a file share. The file share is server 2008R2 and the Citrix session hosts are server 2008R2. The exe file is updated by another person that I don't want to have access to the Citrix servers. Everything works great until he needs to update the exe files. Citrix keeps using a cached version of the exe files until all sessions are logged off. I found another post to restart the Superfetch service and this will clear out the cached copy of the exe file. Server 2008R2 does not appear to have this service. Does anyone know if there is a way to flush this cache?
