Network Neighbourhood

[Alan W]

When i first installed Windows XP, my Network Neighbourhood showed all the
drives on my main system and showed them as shared etc - and all the other
Systems on my small Network displayed correctly.

Now the Network Neighbourhood shows some of the Drives on the system where I
am displaying NN - as being "Unknown" and they do not show under this
Computer Name. Now the C Drive, and G Drives are not shown under this
Computer - only in a Category - Unknown"

Any ideas how to correct this
