Else re-run Windows Cluster validation to generate a new report and this new report will be used by the setup the next time when it runs. I would write another blog in the same series as I found multiple reasons for such behavior. Stay tuned! Please comment and let me know if you found some more causes and ways to fix it.

Is your SQL Server running slow and you want to speed it up without sharing server credentials? Click Next at Possible Owners page. Right-click the cluster group; then select Bring online. Interface the PaperCut Print Provider layer with the clustered spooler service by following the same setup notes as described for Mode 1.
The client and Release Station Print Release Stations place a print job on hold and allow users to release it when required. Often a Release Station is a dedicated PC terminal located next to the printers, however, Release Stations can take other forms such as a web browser based interface. Some common examples where Release Stations can be used include secure printing, approved printing, and authentication. In a secure printing environment jobs are only printed when the user arrives at the print area and confirms his or her identity.
This ensures the user is there to collect the job and other users can't "accidentally" collect the document. In some organizations it may be appropriate to hold jobs until they are approved by selected individuals.
A good example would be a teacher approving printing on an expensive color printer. Users must authenticate prior to releasing their jobs allowing PaperCut NG to confirm their identity. Mode 2 setup is about as complex as it gets! These services are dependent and must be hosted in the same group. Set the Preferred owners of each group to different physical nodes. Restart or bring on line each group, and independently test operation and operation after fail-over.
Take some time to simulate node failure. Monitoring can stop for a few seconds while the passive server takes over the role. It is important that the version of PaperCut running on each node is identical. Ensure that any version updates are applied to all nodes so versions are kept in sync. The PaperCut installation sets up a read-only share exposing client software to network users.
If your organization is using the zero-install deployment method, the files in this share are accessed each time a user logs onto the network. Your network might benefit from exposing the contents of this share via a clustered file share resource. PaperCut regularly saves transient state information such as print job account selections to disk so that this state can be recovered on server restart. If failing over to a new cluster server, you should ensure this state information is saved to a location available to the new server.
You can change this location if required by setting the property server. This location is generally only available on one node in the cluster. This can be done on the same disk that the spool files reside and the Print Provider points to. To change this location, use the Config Editor The Config Editor stores information used by PaperCut to configure advanced options and functions. This information is stored in config keys, which are editable by an administrator.
Click the Options tab. The General page is displayed. In the Actions menu, click Config editor advanced. The Config Editor page is displayed. We would not have too many changes in IIS so can live with a local copy on each node or else can use the Data partition on the shared drives for SQL. In the event of a failover, have an external monitor that could update the DNS alias to point to the backup node.
Each IIS instance could point to the same content stored on your shared storage. That is one idea to test. I've not done much with w2k8 clustering but do have a decent amount of experience with w2k and w2k3. Hope that helps. Failover is then automatic and often "smarter". Good idea on also using a hardware load-balancer to provide WWW load-balancing.
Well WMI and vbscript still exists so it should also be possible to install a script ressource on the cluster which implements the entry point functions needed. Kruda, I am thinking on the same lines as you are suggesting but facing some problems. I guess I am doing some thing wrong or missing some configuration.
That is the reason i was wanting to know if any body has tried it or seen a document to do it. With a load balancing system you can take one of the server out of the stream to update patches etc and balance out the load for when it is running normally.
And use the other tiers in the web env for any clustering needs. To get a applicatin cluster aware i am using generic service which works very fine but i am not able to recognize if my application is hanging.
To recognize that my application is not working anymore i have to make the application itself cluster aware or using my way, namely a generic script implementing the enty point functions. I too had it working acceptably with and IIS6. I'm working with it in my test environment at the moment, but not with much success. Am I wrong in my assumptions that NLB doesn't do service checks and uses another mechanism for knowing whether a node is available? For example if one of the web nodes responds to ICMP, but the web service has failed the request would error out right?
If you are using a hardware load-balancer, you can do basic service level checks and take nodes out of rotation if they are not responding. If an alert came up, the alert action could disable the site. That wouldn't be very pretty but it would work. I currently have my web platform running on a 2 node cluster using Server and IIS6. This allows me to utilize both servers and also the reliability that either server fails, the other will pick up the cluster group and run both simultaniously.
I am looking to upgrade to Server and after reading this post, I am wondering if I am setting my website up correctly. I have two physical machines and a SAN and I want to get the best in terms of reliability and performance. The main problems with the current setup are as follows:. IIS allows you to export the metabase and re-import but custom. Net installations do not.
If we upgrade the app, it has to be done on both nodes independantly. What would people recommend for setting up the two machines, preferably with Server ? Any suggestions would be very welcome. I just came across as I'm about to try clustering IIS 6. In my 8 years of being an IIS Admin this will be my first attempt at clustering, so it should be fun. The reason we are doing this is because we are installing a 3rd party ERP app which requires IIS to be loaded on the app servers, which also run Websphere.
I found that HP article earlier. Any other advice or resources I should look at?
