Not with that tiny bit of information. Q1 - what do you find in the ISA logs for that traffic? -----Original Message----- From: Han Valk [mailto:Han.Valk@xxxxxxxxxxxxxxx] Sent: Saturday, May 21, 2005 7:45 AM To: [ISAserver.org Discussion List] Subject: [isalist] Is the SOCKS4 proxy of ISA 2k4 'unstable'? http://www.ISAserver.org Hi, When I tell Windows Messenger to use the SOCKS4 proxy on my ISA 2k4 server I notice that Messenger looses it's connection every now and than. When I tell Messenger not to use any proxy all is well. Any idea about the cause? Regards, Han. ------------------------------------------------------ List Archives: http://www.webelists.com/cgi/lyris.pl?enter=isalist ISA Server Newsletter: http://www.isaserver.org/pages/newsletter.asp ISA Server FAQ: http://www.isaserver.org/pages/larticle.asp?type=FAQ ------------------------------------------------------ Other Internet Software Marketing Sites: World of Windows Networking: http://www.windowsnetworking.com Leading Network Software Directory: http://www.serverfiles.com No.1 Exchange Server Resource Site: http://www.msexchange.org Windows Security Resource Site: http://www.windowsecurity.com/ Network Security Library: http://www.secinf.net/ Windows 2000/NT Fax Solutions: http://www.ntfaxfaq.com ------------------------------------------------------ You are currently subscribed to this ISAserver.org Discussion List as: jim@xxxxxxxxxxxx To unsubscribe visit http://www.webelists.com/cgi/lyris.pl?enter=isalist Report abuse to listadmin@xxxxxxxxxxxxx All mail to and from this domain is GFI-scanned.
