Intel® RAID Web Console 2 uses the username and password of your server operating system. In Microsoft Windows*, you can use the username Administrator and appropriate password to log on to Intel® RAID Web Console 2.
If that doesn't work, can you perfrom a System Restore on your Windows server 2003 to return your system to an earlier state?
I was using the right username/pwd. In the meantime, I found the problem. Should have checked earlier, but the Security log had audit failures. It looks like I inherited a bad security policy and the 'Access this computer from the network' policy was empty. I put Administrators back in there and it worked fine.
Thanks for your time.
