I have a simple SharePoint environment with a SharePoint 2010 front end and a dedicated SQL back-end. Both virtualized machines running on Hyper-V 2008 R2 host. There are no complicated apps - it is just a file serving SharePoint implementation.
The VHD for the front end server (it only had one drive) got corrupted. I have a Hyper-V export of the complete front end server from the 29th December, including the VHD.
The back end (SQL and all the databases) is unaffected, all the databases are there running happily.
I tried creating a new VM with the three day old VHD from the export, but it does not seem to correctly connect to the back end. The server starts, the Central Administration site runs, the only errors in the event log are Gatherer 114 errors. Central Administration says the databases are started. The websites are all running. I have recycled the application pools and reset IIS.
How to reconnect the front and back end please?
