Vista - Offline Files won't update after change of server name

I'm hoping somebody can help me here, I have been through every forum trying
to find a fix for this problem and it seems a lot of people are having it,
but other than the regedit fix nothing is working other than a rebuild.

My problem:
I was using offlines on a share from a machine called \\Dellp4\share1, this
machine went dead and another was builded but named \\server\share1
My machine XPSnotebook still saw the old share and would not let me delete
it, so I tried the regedit thing discussed by some as:
REG ADD HKLM\System\CurrentControlSet\Services\CSC\Parameters" /v
FormatDatabase /t REG_DWORD /d 1 /f
This seemed to clear my database but now I can not right click on the
network and choose make available offline, it's just not in the menu
When I go to offline files it says 'Offlines files is enabled but not yet
active. restart the computer to activate the computer.'
I restart the computer, but still nothing, I restart again, I disabled
offline files, restart, and then enable. Nothing
Other computers on the network can make the files available offline, just
not mine computer.

Does anyone know how resolve this or how to re-install offline files. I
think a total re-install of offline files might help, but is it a component
that can re-installed?

Cheers in advance
Greg
