the Pocket PC Agent would not install on their Pocket PC's when the Host Computers were running Activesync 4.1
Altiris Agent for Pocket PC 6.1.1134
Any version above ActiveSync version 3.8 is not supported.
ActiveSync 4.1 will be officially supported in the next release of the Altiris Agent for Pocket PC due out by the end of 2006.
Current work-around is to downgrade Active Sync to version 3.8.
