Hi Stefan,
We could not reproduce the token handle leak problem using your modified VB
sample code (modified to use a local XML store and a redmond user account)
on W2K3.
When you run this VB 6.0 test() method repeatedly, does it leak one token
handle for each method call?
If you look at the token handle in Process Explorer, does it show the
username as NT AUTHORITY\SYSTEM or CC\Stefan?
Can you reproduce the problem on other W2K3 systems?
By the way, for performance reasons, recommended approach is to use
InitializeClientContextFromToken, if a token for that domain user account
is available or if you are constructing client context for the user account
under which the code runs, specify NULL for ullTokenHandle parameter.
If a token is not available and if
IAzApplication.InitializeClientContextFromName needs to be used, it is
advised to cache the client context handle returned by
AzApplication.InitializeClientContextFromName for a given domain user
account and use it later for future use in the same process to avoid
expensive membership evaluation/S4U logon calls everytime.
Thanks!
Best regards,
