After more investigations, it turns out that all the un-upgraded servers were refusing to autocreate any client printers. Nothing in the event logs or anything to suggest a problem. I decided the application problem was less of an issue than the autocreation problem and spent the morning upgrading the rest of the farm. No difficulties since. -----Original Message----- From: Joe Shonk [mailto:joe.shonk@xxxxxxxxx] Sent: 10 March 2006 14:29 To: thin@xxxxxxxxxxxxx Subject: [THIN] Re: Printer sutocreation trouble after part-upgraded farm Well, what problems are you having?

I stopped the upgrade after a couple of printing problems were found in our main application but today I'm having all sorts of printer autocreation issues across the whole farm. Could this be related to the half-upgraded farm status? ************************************************ For Archives, RSS, to Unsubscribe, Subscribe or set Digest or Vacation mode use the below link: //www.freelists.org/list/thin <//www.freelists.org/list/thin> ************************************************
