Hi everyone. I restored ISA2000 system state to a problem with the SMTP filter... I am now having this problem The problem occurs every 5 or so days The Web Proxy service failed to create a network socket because there are no available ports on this computer. ISA server already reset the maximal port number to 65535. Make sure this is the value at HKLM\System\CurrentControlSet\Service\TcpIp\Parameters\MaxUsePort and restart the computer to apply this change I investigated the MS article http://support.microsoft.com/kb/321844 Is this the fix ? Any assistance welcome Darryl Janetzki ________________________________ From: [ISAserver.org Discussion List] digest [mailto:isalist@xxxxxxxxxxxxx] Sent: Thursday, 31 March 2005 5:00 PM To: isalist digest recipients Subject: isalist digest: March 30, 2005
