Impossible to remove transient shared folders from the guest session

[Alden]

When I try to remove a transient shared folder from the guest session, I receive an error message after click on OK button. I can't post here the whole message as copy seems not work for it, but some data are:

---

Could not remove the shared folder 'C:' (VERR_PERMISSION_DENIED)

Result Code: E_FAIL (0x800004005)

---

Otherwhise, in My Network Places, in Local Network section is being showed a network folder from a previous removed transient shared folder which currently is not set.

My guest system is a Windows XP SP3 working with host interface, and my host is a Windows XP SP2.

Error message showed by VirtualBox when attempts to remove a shared folder

Such an error should only happen if the sharer folder is still mounted within the guest. So make sure that this folder isn't used anymore within the guest. Please reopen if the problem persists with VBox 3.1.6.
