Help with error installing IIS 5 on W2k

I am adding IIS 5 to a workstation that was recently upgraded from NT4 to Win2k pro. During the configuring IIS portation of the install I get the following message “error witing encrypted data to the web server configuration database” “0x8009000f=Object already exists” and ask to retry/write Unencrypted/write unecrypted all. No matter which option I chose the install hangs. I have tried the resolution from Microsoft Q246183 without any luck. Any other ideas out there?
