I got steam of error in Eventlog in windows 2008 in almost every second.

Question

I had a iSCSI connection and removed the storage NIC card. I don't see anything in iSCSI Initiator Properties. There is no Target Portals or any discovered Target. I restarted iSCSI service, but it didn't help.
Does anyone know the reason?

UPDATE:  I just tried adding the IUSR back onto the administration directory of the site and the upload worked perfectly.  I also found out that the IUSR was NOT removed from the appropriate folder on the 2003 dev server.  So it appears that this is the root cause of the issue.  So other than building a security system using CF instead of Windows authentication, which is probably the best long term solution, does anyone have any ideas for working around this problem?  I'm still stumped as to why it doesn't work in IE, but does in other browsers.  Usually IE is the most friendly in this particular regard.
