NimbostratusMS Print servers
Hi all,
I am planning to use my new F5 LTM to load balance Windows Server 2003 print servers. For the moment, it doesn't work for me: I can see the shared printer but I can't map it.
...
Here's the new link to the guide for creating the WMI monitor. As I recall it was pretty straightforward. I'm even using the same interval and timeout. Looking at my monitor properties, the only thing I see that is different is my alias service port is 3389 and the external program path is /usr/bin/monitors. Also, you'll need to enable remote WMI requests on the win2k8 boxes if not already enabled.

NimbostratusHey guys,
We've just implemented a print server "load balancing" solution using our LTMs where, instead of distributing print jobs across 2-3 print servers, we used priority groups to ensure traffic always goes to a certain print server if it's online. The other server (pool member) with a lower priority would only get the print jobs if the primary was down.
Anyway, I'm using SNAT as the pool members are not on the same VLAN as the LTM. We're also using a simple tcp health monitor on port 515 to determine service health. Everything seems to be working. I didn't have to do a lot of the extra effort I noticed many others went through on the articles I read here on DevCentral.
We went with priority groups as the goal was to understand which printer would get any given pick slip out of our ERP print jobs, so we're not running around the warehouse looking for the printer where a job may have been sent. I'm not uber-thrilled with the health monitor, and have seen some WMI-type monitors that might come in useful.
I guess I'm wondering why I didn't have to deal with all the trouble many others have had? Are my print servers misconfigured, or do those registry changes only come into play when using nPath routing?
Thanks! B
