IIS Fails back when prevent failback is checked

Howdy,
IIS6 Win2003.
Set up the group on Node1. During testing I can down Node1 and groups
and resources failover to Node2. After Node1 comes back online, the
IIS Service Group failsback to Node1. Did I miss something?
TIA for any assistance.
Bill
Bill,
Have you set the failback policy for the group to failback immediately? The default is "prevent failback".
Additional Information:
=====================
To set group failback policy
Open Cluster Administrator.
In the console tree, click the Groups folder.
In the details pane, click the appropriate group.
On the File menu, click Properties.
On the Failback tab, click Prevent failback or Allow failback.
If you click Allow failback, then either click Immediately, or click Failback between and set the time interval.
Notes
To perform this procedure, you must be a member of the Administrators group on the local computer, or you must have been delegated the appropriate authority. If the computer is joined to a domain, members of
the Domain Admins group might be able to perform this procedure. As a security best practice, consider using Run as to perform this procedure.
To open Cluster Administrator, click Start, click Control Panel, double-click Administrative Tools, and then double-click Cluster Administrator.
To set the time interval for Failback between, enter numbers between 0 and 23 for the beginning and end of the interval. If the first number is greater than the second, the interval ends on the following day. The
numbers correspond to the local time of the cluster group, as read on a 24-hour clock.
It is important to set the failback time because you may not want failback to occur during hours of peak usage.
If no preferred owners are specified for the group, then failback does not occur.

|||Uttam,
I have the failback property set to 'Prevent failback'. Yet the IIS
Services Group continues to 'Failback' when the Node comes back online.
It does not seem to interfere with the functionality of IIS running from
the other Node though. While looking at the properties of this Group I
did notice a differnce in the failover threshold and period. On the
other two groups the I have the Threshold set to 10 and the period set
to 6 hrs. Would this have an effect?
Thanks again,
Bill

Shutdown node 1 and verify that all resources come online on node 2.
If you don't want to shut down node 1 then move all resources to node 2 and pause node 1. make sure that all resources are coming online on node 2. If it fails then see the errors in NT logs and cluster.log and fix
them first.
You mentioned something about the difference in group properties? What is the difference that you saw ?
You wrote "On the other two groups the I have the Threshold set to 10 and the period set to 6 hrs. ". This is the default. What are the values on the IIS group? Did someone change it from the default?

If I down Node1, failover to Node2 works as designed no issues, when
Node1 comes back online, the IIS Services Group failsback to Node1.
There is no loss in functionality, IIS works as needed. It is just that
the Group fails back to the other Node.
I did Move the group to Node2 and it has stayed there, it is just during
failover from 1 to 2 that the anomialy occurs.
Settings were: Threshold 1, Period 2. I may have changed them some time
back (I fell off of testing for almost two months).
Thanks,
Bill
