IDiskQuotaControl::InvalidateSidNameCache

Invalidates the contents of the system's SID-to-name cache so subsequent requests for new user objects (IEnumDiskQuotaUsers::Next, IDiskQuotaControl::FindUserSid and IDiskQuotaControl::FindUserName) must obtain user names from the network domain controller. As names are obtained, they are cached.

HRESULT InvalidateSidNameCache(void);
