Every day I've got users comming to me saying that they can't print to their networked printers and I cannot, for the life of me, find the solution. All of their printers will say <Unable to connect> for a seeminly random length of time at seemingly random times during the day.
We're on a small/medium lan with about 50 workstations and several servers. The servers are all WinNT 4.0 and the workstations are a mix of NT 4.0 and Win2K Pro. We have a new dedicated print-server (400MHz @ 384MB Ram) which just replaced one of about 1/4 the power (we thought that would fix the problem). Everything runs through three Intel Express 510T switches with the users and printers pretty evenly distributed among them.
Other notes that my help: the print-server and most of the printers have static IP addresses. Most of the <Unable to connect> messages happen around 3pm but have happened to most people throughout the day. I cannot see any pattern in the location of the users or their place in the switches as compared to the people who have the problem.
This isn't necessarily urgent but it is infuriatingly annoying to not only our users but the customers they have to serve. Any and all suggestions will be appreciated.
