GetLastError returns success after InternetSetCookie returns false
.everyoneloves__top-leaderboard:empty,.everyoneloves__mid-leaderboard:empty,.everyoneloves__bot-mid-leaderboard:empty{ height:90px;width:728px;box-sizing:border-box;
}
Using .NET 4.6.2, coding in C#
Having a problem for just a customer on a handful of their machines. When the user is in Local Administrator group, everything works fine but when they remove them from Local Administrators, it would appear InternetSetCookie returns false, but GetLastWin32Error returns success.
I concluded InternetSetCookie is returning false, because I fail to see any line above it could possibly throw such an exception. But I guess anything is possible.
[DllImport("wininet.dll", CharSet = CharSet.Auto, SetLastError = true)]
static extern bool InternetSetCookie(string lpszUrl, string lpszCookieName, string lpszCookieData);
private bool SetUriCookie(CookieContainer container, Uri uri, string cookieName){
bool bRetVal = false;
try{
Cookie cookie = container.GetCookies(uri)[cookieName];
string cookieValue = cookie == null ? "" : cookie.Value;
DateTime cookieExpire = cookie == null ? DateTime.Now.AddMinutes(2) : cookie.Expires;
string cookieData = string.Format("{0};expires={1}", cookieValue, cookieExpire.ToString("R"));
bRetVal = InternetSetCookie(uri.ToString(), cookieName, cookieData);
if (!bRetVal) throw new Win32Exception(Marshal.GetLastWin32Error());
} catch (Exception e) {
Logger.LogError(e, "Exception thrown attempting to store '{0}' cookie", cookieName);
}
return bRetVal;
}
This is what logged is:
Exception thrown attempting to store 'xxxxx' cookie Error: The operation completed successfully
I have reason to believe the cookie is being stored, even though the API returns false. I have yet to confirm that. Any suggestions on how I should proceed?

@HansPassant, I would agree if the cookie wasn't being saved, however, it would be nice to give them a clue what to look for. But it appears the cookie is being saved and obviously would impact my error handling code.
