iscsi 'negotiation problems'

We have installed and loaded the UNH_SCSI and UNH_iSCSI target
(1.5-01) on the Fedora Core 1.0 distribution.

As a initiator we use an computer installed with the Cisco iSCSI
driver (version 3.1.2) on a Windows 2000 installation.

The target listens on port 3260 for incoming initiators.
When inititating by means of the Cisco driver, the result is a status
HELD. According to the Cisco documentation it means that a target is
discovered but login failed.

After a relogin on the target W2K shows a message that there was an
unsafe removal of device (Cisco pseudo scsi diskdevice).

The messages in /var/log say the target received an InitiatorName
twice,
text_param.c ***ERROR*** key 'initiatorname' received twice

followed by

target_negotiate.c ***ERROR*** check login failed
iscsi_target.c ***ERROR*** parameter negotiation failed
iscsi_target.c ***ERROR*** trouble in handel_login

Can anybody help us with this problem? We have tried varios options
without any result.

Thanks in advance.
