user error when writing to shared drive

[TheBaron]

I have create a vb.net app that creates an excel spreadsheet. When I deployed the app, to the shared drive, I have no problems but the user gets the below error. The user can create the spreadsheet but gets the error when writing. When the user logs onto my PC, the user does not get the error. When I log onto the users PC, I got the error. So I believe it has something to do with the pC.

Application attempted to perform an operation not allowed by the security policy To grant the application the required permission, cintact your local system adminsitrator, or use the Microsoft .net framework

request for the permission type 'System.security.permissions.securitypermissions mscorlib

version 2.0.0.0 culture =neutral
Publickeytoken='b77a5c56193e089'

I have tried to use caspol but to it doesnt help

thank you

Is the shared drive mapped under an Alias name, or is it being referenced as a UNC path on both PC's?
