LookupAccountName fails on vista with ERROR_NONE_MAPPED
I'm trying to cal开发者_StackOverflowl LookupAccountName on Vista - it always fails with the error ERROR_NONE_MAPPED.
What could be the reason??
Thanks!!
ERROR_NONE_MAPPED typeically means that the username you provided is not available in the format you specified.
Try disabling UAC on the your machine. It should work after that.
