Glad its helped you. i had a look around in regards to your issue eddyc. Like you say not much to get your teeth into in regards to help on the internet. Unfortuantely i cant replicate your issues here. Have you tried rebuilding the computers that are having the problems incase something has become corrupt ?
I've reimaged the suspect machines and sure enough, after applying the hotfix all of the printing complaints have stopped. Thanks so much!
I map printers via logon script, API call and printers always map, granted a bit slow while windows maps the connection during logon. Never GPP to add a printer as I don't have control which users get what printers dependent on things like building or specific PC or AD group.
The old way is the best!!
