Ip is good, clients can browse, but not hit exchange . These are REMOTE clients that are not on the LAN. Clients can resolve esrver name, but cannot chek name in exchange, can telnet into port 135, 25, but not connect. Yet three other machines in that REMOTE office can connect. the only difference is the machines that can connect are w2k, the two that cannot are nt4 -----Original Message----- From: Jim Harrison [mailto:jim@xxxxxxxxxxxx] Sent: Tuesday, July 24, 2001 12:21 PM To: [ISAserver.org Discussion List] Subject: [isalist] Re: Outlook through ISA http://www.ISAserver.org Verify their IP settings; are they WEB, FW or SecureNAT clients?

My remote W2k clients can connect through the firwall fine, but i have two nt4 clients that cannot connect, they continually recieve time-outs., Does anyone have any idea as to what would be different in nt 4 as to not allow outlook connectivity through ISA ? ------------------------------------------------------ You are currently subscribed to this ISAserver.org Discussion List as: jim@xxxxxxxxxxxx To unsubscribe send a blank email to $subst('Email.Unsub') ------------------------------------------------------ You are currently subscribed to this ISAserver.org Discussion List as: msivak@xxxxxxxxxxxxxx To unsubscribe send a blank email to $subst('Email.Unsub')
