After you change a user account name, the LookupAccountSid function still returns the old name.
The LookupAccountSid function accepts a security identifier (SID) as input. It retrieves the name of the account for this SID and the name of the first domain on which this SID is found:
If the LookupAccountSid function is called with a NULL lpSystemName function, it looks in the SID cache on the local computer before it goes to a domain controller. If an entry is not found or if the entry has expired in the SID cache, the domain controller is contacted. If this entry is a new entry, it is added to the SID cache on the local computer. If this entry is an expired entry, the refresh time is updated to the current time. The entries in the cache expire every five minutes. For expired entries, only the refresh time is updated. As a result, if the account name is changed, the SID cache contains the old name until you restart the computer. Because the domain controller is contacted when the entry in the SID cache expires, the correct name is returned on the first call to LookupAccountSid after the entry expires. However, the SID entry is not updated with the correct name in the SID cache and later calls return the old name.
