Allen,

I have had a look on the list of UDF's but I'm not seeing the RunAsInteractiveUser UDF, could you tell me where I can find it? Also when you say In the GPO use the UDF to call the logon script I'm not sure I'm following you on this. I have not used UDF's before and I've had a quick look at how to use them and the guide tell's me to simply add the function at the bottom of the logon script.

Thanks for your assistance
