Error parsing Request: The request subject name is invalid or too long. 0x80094001 (-2146877439)

I have an offline Enterprise CA based on Windows Server 2003 Standard. I am
trying to sign a certificate request generated from a Windows Server 2003
Enterprise R2 CA. When I choose submit new request on the offline CA, I get
this error.

I have no idea what the error means. Some guesses though :-) :

- There is something wrong with the format of the name. I would have hoped
the R2 online issuing CA would have told me what is wrong with the name
- The name is too long maybe? Again, I dont really know how long the name
can be, but I dont think the names I have chosen are ridiculously long.

Am I missing the boat on this one?

I am using Brian Komar's excellent reference as a guidepost, and dont see
anything in there that can help me with this one.

I did find one other thread via google, but it seemed to be related to cross
certification, and I am not doing anything like that.

I think, that there is no name in the request. You can try to submit
this request via web interface (there you can write some additional
properties of request).

If someone gets that error when is using firefox o other browser to request the certificate. It will be solved using Microsoft Explorer to request it.

I forget, to use firefox o other browser different to explorer you can do
