Active Directory, enumerating user's groups, COM exception

Question

while enumerating current user\'s groups through AD .NET API I sometimes get

COMException: Unknown error (0x80005000)

Here\'s my code :

Answer 1

0x80005000 = E_ADS_BAD_PATHNAME so you supply an invalid adspath somewhere, maybe you must add LDAP:// prefix or opposit are doing this twice? Set a breakpoint and inspect value...

EDIT: AdsPath should be a value like "LDAP://CN=Administator,CN=Users,DC=contoso,DC=com", you seem to have a misformed path.
