We have 2 web front ends hosting our MOSS 2007 portal. One of these WFEs (I'll call it WFE2) is causing publishing errors and strange behavior within the portal when it is added to our load balancer.
The load balancer is IBM's Network Dispatcher version 5.1.1.49. It is software based.
I removed WFE2 from the load balancer. I added the IP address and site URL to my laptop's host file to test out our portal site on WFE2 via my laptop. It functions properly. I log onto the WFE2 server and the site functions properly.
I was told by one of our server managers that the IBM network dispatcher only redirects traffic to the WFE's, it does not handle any return traffic to the client.
The errors we are experiencing include:
1. Unable to add selected web part(s). Image Web Part: An error has occurred - It says the same thing for any web part we try to add to a page.
2. The page you are attempting to save has been modified by another user since you began editing. Choose one of the following options: preview existing version, save and overwrite existing content, exit without saving.
What we have tried already:
1. Disconnect WFE2 from load balancer. WFE1 works fine, but we cannot have all of the traffic going to that box alone.
2. Verified IIS settings were correct.
3. Detached WFE2 from the SharePoint farm and reattached it. This did not work.
4. Rebuilt the WFE2 server, completely wiped the server and reinstalled Windows 2003 server SP2, MOSS 2007 and SP1 for MOSS. Installed .NET Framework 3.0 SP1. Verified all of the same software and patches were installed on WFE1. Reattched WFE2 to the farm successfully. This did not get rid of the problems.
5. Created another web application to test without affecting our Production portal. This did not work, the behavior still existed in the new web application.
Microsoft engineers seem to be clueless when we contact support. We've had 4 engineers from there and none of them have offered good advice or a solution. If you have any idea what to do here, please let me know.
