Hi,

I have two print servers: one running on windows server 2003 and the other one on windows server 2008. How can I set up load balancing of printers between these two servers?

Thanks

That's a very broad question, and asks for much more detail than what this site is designed for.

I'd suggest you start by reading documentation first and then if you have actual problems or need help, then come here.

Here's a few good places to start:

thanks dhoffman but this is simply what i am looking for:

Windows Print Server Load Balancing (NLB)
The following implementation is a solution where we can have redundant print servers serving all the print queues and migrate all of them without any outage.
1. Configure NLB on the 2 servers using the "Network Load Balancing Manager" (part of Admin Pack) use a dedicated NIC on each server and use unicast. Some CISCO routers do not pass ip address with multicast MAC addresses
2. Set NLB Port Rules to listen on port 135 (TCP/UDP) and ports 1024-65535 (TCP/UDP)
3. Configure the print queues identically on each server including Printer Name, Share Name, Driver etc. You can setup all your queues on one server and migrate them over using the tool to the second server very easitly.
4. Make the computer policy change on both servers. On the Local Computer Policy set "Computer Configuration > Administrative Templates > Printers > Allow Print Spooler to accept client connections" to Enabled and restart the Print Spooler service.
5. Manually create a DNS A record pointing to the IP of the NLB Cluster.
New mapping would be done with \\NLBClusterName\PrinterShareName. For users who are still mapped to the printers using old name, first you add a DNS A record for the name of each of the old print servers which points to the new cluster IP. Be sure to remove the old DNS entries or rename them to avoid duplicate name and un-planned outage
7. Add an alias entry for each old server name you want the new server to be identified with on the new load balanced servers. The idea here is, if anyone uses old server name to map their printer, they'll automatically be re-directed to the new one.
Navigate to registry hive, HKEY_Local_Machine\System\CurrentControlSet\Services\LanmanServer\Parameters
Add Value: OptionalNames REG_SZ String: "Alias"
If you make it a type REG_MULTI_SZ, you can add multiple aliases.
If do not like step 7 and feel that you shouldn't be dealing with old print server names then use login scripts to re-map your users to the new print server or deploy a software package using a software deployment tool (SMS, Altiris etc) to re-map them.
