CSM load-balancing with MS Print Servers

[mbraeunlein_sie]

We are trying to load-balance print server connections between 2 MS print servers. When we try to connect to the VIP address, we get a Path not found error. However, if we direct the path to the actual name or ip address of the print servers (not the VIP), we can view all the queues and connect/print to them. On the CSM we use client nat.

Is is possible do connect a share with the VIP address and open files.

I would think this is possible.

Did you capture a sniffer trace on the server side to see what's going on.

Did you try to enable stickyness ?

I did not enable stickyness. I've done a capture with ethereal at the server (see attachments). 10.11.187.211 is the client nat address, 10.11.195.171 is the physical server address, 10.11.187.2 is the vip address.

The printer is accessible when using the physical server address.

I think the problem is that the CSS will nat ip address in the ip header but not in the tcp data.

So, when requesting to print to 10.11.187.2, this address is sent to the server and rejected because unknown.

What we can try is configure a loopback on the server [if possible] that is the same as the vip and configure each service on the css to be 'type transparent'.

Like CSS, will not nat the destination ip address and the server will accept the request because it knows the address as its own loopback.

Let us know if this works.

Good news. If configured 10.11.187.2 as loopback on the server and it works! Thanks for your help.
