I have currently upgraded our servers to 2008. In doing so I now have a Small Business Server 2008 running as a PDC and Server Standard 2008 64 bit running TS services.
The SS machine which is running as a Terminal Services server. For some unknown reason all users find using a Terminal session to this server very slow, with a small lag seems to occur when opening windows and typing text.
The server is an Intel custom of a very high spec, we have run full diagnostics and fully checked the internal RAID (which is running 2 mirrored drives). There is absolutely no hardware issues at all. I have also installed a new harddrive, setup the OS again from scratch and re-configured the server, still the same issues occurs. I then setup one of the old Fujitsu Siemens servers with a new HDD, setup the OS and re-configured the server exactly as the Intel server. This server runs perfect with no lag at all, which is annoying as it is nowhere near the spec of the intel server. The only difference between the two servers is that the Fujitsu is running a 32bit version of 2008 and not 64.
The clients have all been updated to the latest version of RDC and are running 32bit versions of XP Pro with a few running Windows 7.
Please can anyone shed any light of this very frustrating situation.
