From MPS3's admin guide - 'By default, ICA sessions connecting over TCP use maximum sized TCP packets (up to 1460 bytes of data) for the transmission of large amounts of data. However, there are a small number of network types, usually wireless or satellite-based networks, where better performance can be achieved by using smaller packets. You can change the normal maximum size (1460) on a server by setting the following registry entry: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\TerminalServer\Wds\icawd \MaxICAPacketLength' This is a valid option in FR3/MPS3 but does not appear in the advanced admin guide for MPS4 Anyone know if this is a redundant setting in this version - or has it just been overlooked?
