Disable "simple file sharing" on XP pro.
Didn't work
How do you know the share isn't there, as this share is never visible by browsing the network.
Try mapping a drive letter to it: \\xp_box_name\c$
One of the way to see the share is typing
net share in CMD

Causes: These issues may occur after a malicious or spyware program removes the administrative shares on a windows computer. You can use "net share" command to check that the administrative shares are active. if yes, you must have admin$, C$ and IPC$.
Resolutions: To fix it, please follow these steps;
a. Click Start, click Run, type regedit, and then press ENTER.
b. Locate and then click the following registry sub-key: HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\LanmanServer\Parameters
c. If the AutoShareServer and AutoShareWks DWORD values in the LanmanServer\Parameters sub-key are configured with a value data of 0, change that value to 1.
Note If these values do not exist, you do not have to create them because the default behavior is to automatically create the administrative shares.
d. Quit Registry Editor.
f. Restart the computer.
