Hi, That was what the customer decided to do. The alternative was sticking print servers out in several hundred branch offices (to support 2-3 client PCs each). And in Australia a branch office can be a whole days drive there/back for a support technician - so they get quite expensive to maintain.
Also, from memory I think a lot of the applications used by these retail branches were thin-client (running off mid-range or mainframe in the DC) so the print jobs would go from the midrange system to the print server and then only the data necessary for the printer to print something was sent over the WAN link Cheers Ken From: Malcolm Reitz [mailto:[email protected]] Sent: Saturday, 4 April 2009 2:25 AM To: NT System Admin Issues Subject: RE: Redundant Print Servers Ken, Did you guys take a look at the bandwidth utilization when sending all the remote site print jobs to the central print server and back to the local printers again? I can understand why you'd want to centralize the print sharing, but, admittedly without having really looked in to this, I'd be a bit concerned about burdening the remote site WAN links with print jobs. -Malcolm From: Ken Schaefer [mailto:[email protected]] Sent: Wednesday, April 01, 2009 6:31 PM To: NT System Admin Issues Subject: RE: Redundant Print Servers We had a 30-odd page detailed design, and a 30 page implementation guide, a DR guide, ops guides etc... This was for a reasonably large organisation (around 10K users) who wanted to have a centralised print server cluster in one data center for all their small branch sites (several hundred of those), as well as a second print cluster in the DR data center. The failover was between these two data centers, as the customer didn't want to pay for a stretched cluster just for printing. And they wanted users to be able to search AD for printers. That last part was the kicker. In a DR situation, the only thing that needed to be changed (IIRC) was the cluster that the DNS hostname was pointing to. The rest of the ops work (e.g. creating the print queue objects) was all handled by a little wizard based HTA application that we wrote (IIRC) and worked into the operations processes of the org.

When we make a change to an active printserver, we do the same on the passive, or we're supposed to :-) The way we handle redundancy is to use a dns alias, so we have srv-print<sitecode>01 and srv-print<sitecode>02 with the dns alias of srv-print<sitecode> If the active server goes down, we just change the dns entry to point to the other server. The only problem with this is that if the user goes to add a printer and selects the Find in directory, it lists the queues on the actual servers. I've created a vbscript that checks the users printers and if its not connected to the alias, it deletes it and re-maps to the alias queue. I can pass on the script if needed. You also need to do the following reg edit otherwise you get a duplicate name error.

(That is, one server hosting all printers goes down, the other takes over; alternately, two servers share the load usually until one crashes and the other takes over?) I can think of a couple of ways to handle this, but I'd like to know what "everyone else" is doing... Regards, Michael B.
