The "ERROR_INTERNET_CANNOT_CONNECT" error occurs when you send Web requests by using NTLM authentication in Windows 2000 (331862)


The information in this article applies to:

  • Microsoft Windows 2000 Server
  • Microsoft Windows 2000 Professional
This article was previously published under Q331862

SYMPTOMS

When client computers send Web requests by using NTLM authentication to a Microsoft Windows 2000-based computer that is running Microsoft Windows HTTP Services (WinHTTP), the Web requests may not succeed. Additionally, the following error message may be logged in the log file that is generated by the trace configuration tool, WinHttpTraceCfg.exe:
80072EFD
# as an HRESULT: Severity: FAILURE (1), Facility: 0x7, Code 0x2efd
# for hex 0x2efd / decimal 12029 :
ERROR_INTERNET_CANNOT_CONNECT inetmsg.h

CAUSE

This problem occurs because WinHTTP remains in the TIME-WAIT state for some time before releasing a closed connection to be used again. A port must pass the TIME-WAIT state before the port is released. This behavior may cause Windows to run out of dynamic ports because a maximum of 3975 ports are available.
