MS 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.
Monitoring WMI Services from Big-IP

Hi there,
I'm also fighting with MS print servers behind the BIG-IPs.
Based on the two Threads here in the Forum we configured nPath as described and also configured a loopback on the print servers with the VS IP-address. Also the two mentioned Registry tweaks were implemented.
But we still only get the listing working, nothing more. With setting the Metric for the loopback to 2 nothing was working, also ping monitoring from the LB to the print server was red then. That's why we removed it again.
Basically I'm also wondering why nPath routing is necessary at all. Normally nPath routing will only be used if you have a huge amount of outgoing server traffic, which should not go through the BIG-IP (to save resources and internal throughput). From a technical point of view nPath or having SNAT enabled should be the same, only difference with SNAT you have one additional hop for the response.
So can someone explain, why nPath is technical required for MS print servers? And does anyone has an additional idea, why it's not working for me? Btw. the result, that only listing is working is the same using nPath or SNAT.
Thank you!
Ciao Stefan :)
