SYMPTOMS
When the Win32 LookupAccountSid function is called by multiple users, it may not work. This occurs when multiple users makes an RPC call to the server. For each RPC call coming from the client, the server impersonates the client user and calls LookupAccountSid. Calling GetLastError returns ERROR_INVALID_HANDLE.
CAUSE
If many users make RPC calls to the server and a condition arises in which the close for the last connection comes before the bind for next connection, the server returns BindNak to the client and the call does not succeed.
