Does anyone have any sample code which will show me how to load all the Microsoft exchange 2000 servers within the organisation into a dropdown combo box? Thanks Regards Mohammed

I have an application which works fine on my home computer, however when I try to run the same application over the network on the computer in the office I get an error An unhandled exception of type system.security.securityexception occurred in MSOTest001.exe Addtional information:System.Security.Permissions.SecurityPermission This error is driving me nuts...I hope there is someone who can advise me as of what to do. Thanks Regards Mohammed
