I did implement it in many places and it works great!!! IT's great for easy roaming. Will you use the default windows 2003 Certificate authority or will you use a 3rd party tool?

We currently have Windows 2000 PS 3.0 and I'm looking to upgrade to Windows 2003 PS 4.0. Our clients are all Wyse 9441GXL that connect to a published desktop. We are looking at implementing Smart card login (PKI) from all our clients/servers. Do you think this will work through ICA? Any advise? _________________________________ Hector Minero NSWCDD Code K55 Ph: (540) 653-8859 Fax:(540) 653-8575
