I can't add a target portal using Microsoft iSCSI initiator on Windows XP. I've installed the MS initiator (version 2.05)on an XP (SP2) desktop and I'm attempting to add the target. I've entered the IP address of the iSCSI target and accepted the default Port of 3260. I'm getting an error "Connection Failed" in a small dialog and the application log shows an Event ID 1 for iScsiPrt [Initiator failed to connect to the target] and Event ID 113 in MSiSCSI [iSCSI discovery via SendTargets failed 0xefff0003 to target portal].
I've confirmed that the Windows firewall is not enabled, and I have confirmed that I can send ICMP (pings & traceroute) to the Target address. This doesn't look complicated, but it isn't working. What else should I try?
