0 I got a call from a client 2010-Sep-16 that they could no longer print to either network printer from any workstation. Workstations have Vista Business 32 and were updated morning of Sep 16. Server is Server2003 & printing still worked from it fine. Printers were using IP ports fine for over 2 years. Fix was to create ports with full share name & use that instead of IP. The IP address of printer had not changed AND I could still browse with IE8 (using IP address) to printer to see config data of printer Workstations are in Server2003 domain This full share name trick was how I previously had to set up Vista Home Premium workstations to use network printers in home networks. Why would Vista Business be "updated" to Home Premium settings? Is this a permanent "update"? Why does any version of VISTA do this? Does Windows 7 have same issue? With Vista Business 32 the (short term?) solution was to change the port to a local port with the full share name of the printer If this were to happen to the server, I think the fix will be unworkable unless the printer is directly attached to the server.
