Windows 7: Sharing a C drive

ok I tried everything and can't figure this out.
I have 2 PC running Windows 7 home premium and 1 xp spack2.
I have the Local hard drive on both 7 and I am able to access them however on xp which is on the same workgroup and ip address.
When I go to map the drive it comes up with a error message
i
is not accesible. You might not have permission to use this network resource.Contact the admin of this server to find out if you have access permissions.



Please help

Thanks for the quick reply. I read and followed this earlier. It is only with my xp machine unable to access the c drive however I can access the 2 usb drives connected to the PC. I am stumped big time

You would need to allow for the usual sharing permissions of the drive but you also need to go into the Security tab of the drive and allow for access to the drive by adding "Everyone" to the shared with list. That should give your XP machine access to the drive.

Sometimes just putting check marks for the Authenticated users is enough, other times you need to put "Everyone" on the shared with list.
