i've developed a client application with c#

this application calls web services in a websphere server

i've implemented the criptography using wse 1.0 sp1

at the moment the calls by xp client run correctly

if i try from a windows 2000 client i receive this message (in the client)

"non negative number required.

parameter name: byteCount"

can anyone help me

thanks

My initial instinct on this is that the certificate used to encrypt the message may not be on the Windows 2000 machine.  You may want to check the storelocation properties to insure that the location is valid on both machines.  The actual code normally required is not different between Windows 2000 and Windows XP clients.

Also, is the Windows 2000 client the professional or server operating system?

Do you know what method takes the parameter byteCount?
