Windows Vista Ultimate gets "licensing protocol" error running Remote Desktop Connection. RDC did connect to local Win 200 Server and only recently began getting this error. A fresh install of vista on this client does work so I copied the MSlicensing key to the troubled instal - but no luck. Other Vista and Xp clients on the local network connect with RDP OK. Wondering what other areas of registery or services relate to RDP that I should check to avoid re-install of Vista & all programs?
