On my latest install of SharePoint 2013 Preview, I encountered an error when running the Configuration Wizard. After the wizard had been running for a while, I got the following error:
Exception: Microsoft.SharePoint.Administration.SPUpdatedConcurrencyException: An update conflict has occurred, and you must re-try this action. The object SPAdministrationWebApplication was updated by SHAREPOINT\sp_setup, in the psconfigui (2960) process, on machine SP2010. View the tracing log for more information about the conflict.
at Microsoft.SharePoint.Administration.SPConfigurationDatabase.StoreObject(SPPersistedObject obj, Boolean storeClassIfNecessary, Boolean ensure)
at Microsoft.SharePoint.Administration.SPWebApplication.UpdateAuthenticationSettings(SPUrlZone zone, SPIisSettings newSettings, Boolean createJob)
If I remember right, it mentioned this was a issue in provisioning Central Administration. I had an idea as to what the cause is, but I figured why not just try the wizard again and hope it goes through. You know what they say, “if first you don’t succeed…”. I ran the Configuration Wizard again and sure enough it completed (rather quickly I might add). When you run the wizard again, just choose Do not disconnect from farm. Then type in your port to run Central Administration and you should be good to go.
