Cannot Add Second FE Server to SharePoint 2010 Farm

Hi folks

Well I thought I would add my problem to the others that are also experiencing this issue. I actually reported somthing similar to this forum in Feb 2010 when I was trying the beta version out.

I upgraded our WSS farm to SPFS 2010, the upgrade worked, well kinda. Basically our second WFE server would not join the farm after installing the 2010 binaries and runnng the configuration tool and it was complaining with the following error:

07/31/2010 14:35:59  11  INF                              Calling SPFarm.Local and SPServer.Local to get the local farm objects
07/31/2010 14:35:59  11  INF                              SPFarm.Local returned null.  This usually means that the server is not joined.  But, you can delete a server from the configdb without unjoining, which would mean that this machine still thinks it is joined.

In the event log I see the following:

So I decided to create a new VM and install SPFS from scratch and attempt to join the farm. This still didn't work. So now I am at a stage where we are a front end server down and risking a service outage if problems are experienced on the sole WFE server. I am using the sharapoint farm admin account for the install and have checked and double checked everything.

I would be very happy if someone has a fix for this.

Thanks
