I have a SharePoint 2010 SP1 CUs up to Dec 2012 Farm.
Consisting of:
3 - WFE
2 - APP
1 - DB Cluster
We do not have load balancing turned on or configured. If I point our SharePoint URL via DNS to WFE1 everything works just fine. If I point the DNS to one of the other WFE's my users can not Edit, Save, or Upload documents and are met with very vague error messages.
"Upload Failed: Your changes were saved but could not be uploaded because of an error"
It seems Workflows also stop working.
As soon as I point back to WFE1 everything works fine. Mind you the only thing that appears to break when point to one of the other 2 are workflow and the ability to edit, save or upload documents, they open just fine.
I am at a complete loss here. All of my WFE match, so I do not get what I am missing. Any help is appreciated, thanks for taking the time to read.
