Hi, I'm getting 0x00000057 when trying to install a printer on Vista clients from a Samba hosted printer server. The packet traces shows the last transaction is GetPrinterDriver2, but I just don't see what's invalid in the reponse. I have tried 3.0.22, 3.0.26a, and 3.0.28 and they all give me the same error. Can someone please help? Thanks! --MingJ
