security problem in vs2005 not in 2003

[Guest]

i have a simple (1 form) Winforms VB.net 2003 app and am migrating it to
vb2005

testing both on the same box...

if i run the 2003 version it works correctly, but the 2005 version fails
when attempting to connect to a SQL Server database.
looking at the connection object after the attempt i have an exception
object in the WorkstationID:-

"Request for the permission of type
'System.Security.Permissions.SecurityPermission, mscorlib, Version=2.0.0.0,
Culture=neutral, PublicKeyToken=b77a5c561934e089' failed."

in the 2003 version i have a valid workstation id

the code to this point is identical

any ideas?
