OK, maybe I didn't explain the problem in a clear enough manner last time, so let me start all over again...
The two main machines involved are:
Machine A: Sony laptop running Windows Vista. 1 hard drive
Machine B: Desktop running Windows XP Pro SP3. 2 hard drives.
We are trying to get Machine A to access both hard drives in Machine B. We have shared both hard drives in Machine B. Machine A has full access to the C drive in Machine B(the main drive). No problem. Then we shared drive D in Machine B. Machine A can see it, but not access it. We used the same sharing proceedures as the C drive, but are still not able to have full access to the D drive in Machine B. We are getting an error message that says we don't have the proper permission to access the D drive in Machine B. Simple file sharing is activated and we can still only see the D drive in Machine B...not access it.
Accessing the C Drive in Machine B is still happening, but we can still only see the D Drive and not access it.
Since our error message says that we don't have the proper permission to access the D Drive in Machine B, we gave the "Guest" administrator permissions in the Users on Machine B...but still we cannot access the D drive in Machine B. It still says we don't have the proper permission to acces it.
How do we give permission to access the D Drive in Machine B?
