Thanks for the help - ITunes & Quicktime changed 65 startup processes and caused the following error - Detection of product '{4F5CE18C-D97D-48FF-A510-A0D90C918294**', feature 'iTunes' failed during request for component '{E8A1D3E2-F5D3-4B24-AB93-52F7E602A235**' Windows Update also installed a new driver for the network adapter (which I've just rolled back)

I've just found a forum which suggested opening command prompt and tapping in -
net localgroup "Administrators" "NT Authority\Local Service" /add

then reboot - the network icon is now showing as connected and everything appears to be running smoothly.

However event viewer is still showing the following errors -

Service 'WMPNetworkSvc' did not start correctly because CoCreateInstance(CLSID_UPnPDeviceFinder) encountered error '0x80070005'. Verify that the UPnPHost service is running and that the UPnPHost component of Windows is installed properly.

The print spooler failed to share printer Brother DCP-120C USB Printer with shared resource name Brother DCP-120C USB Printer. Error 2114. The printer cannot be used by others on the network.

The LogMeIn Kernel Information Provider service failed to start due to the following error: The system cannot find the path specified.

Looks like I'm stepping in a minefield!
