Domino R6.01 setup failed

I had a R5.08 server running on Win2000 and wanted to upgrade it to R6.01.

I followed the the process described in the IBM Redbooks and so far everything was looking fine.

However the server does not start. It crashes first time I started it raising NSD.

I got a few times the Error 0x143 as others mentioned in their post.

Now the error is gone after trying to start the server a few times.

Did anyone face the same problem? Any solution?

If you need more information, please let me know by answering the post.

Thanks in advance
