We had a windows 2003 R2 server deploying printers through group policy. The server was replaced with a server 2008 R2 box and printers were done from scratch without GP.
No one realized that the old printers were still being deployed from GP that tranferred with the domain.
A seperate GP object was created for the printers on the oringinal server and this was simply deleted from the GP on the new server and gpudate was run thinking that would stop the deployment. but the printers are still being deployed during login and we can't figure out where it's comming from.
