CVS and Windows paths... the nightmare reloaded

if some smart guy installed CVS on Windows (using cvsnt) and mapped a repository using a full path name, such as d:\cvsroot.... well, you MIGHT be able to access to it from Windows CVS Client, but forget about accessing from Unix... I have tried everything and it simply doesn't work.
The final solution is:
tar and feather the guy who made this mapping, and create a mapping without the d:\

Furthermore, if you do (Hudson does it to check if anything new has been committed since the last build)

[weblogic@CRM-INTG-DEV ACME_INTEG_EAR]$ cvs -q -z3 update -PdC -D "Wednesday, February 10, 2010 1:01:29 PM UTC"

and you get:
cvs server: cannot open directory . for empty check: Input/output error
then you might have to give Full Control to Everyone on the TEMP directory used by CVSNT on the server....

CVS, who needs enemies when I have a friend like you!
