[cvsnt] Error : Cannot change permissions on temporary directory

[Gregory Vignal]

Hi,
 
    I have installed the last build release cvsnt version 2.5.03.2152
on a windows 2000 server and i have problems to make cvs running
normally. 
Only cvs login command work properly, all other cvs command give this
error : "cvs [server aborted]: cannot change permissions on temporary
directory D:\cvs_temp/cvs-serv4176: Permission denied". 
 
I have set properly all permissions for all my cvs users ( including
SYSTEM / USER WITH RIGHT ). All user have full acces control to the CVS
TEMP repository.  Users can create file or directory in "D:\cvs_temp"
behind network.  I dont understand why this error message appair.
 
    The only way to make cvs work is to give administrator right for all
cvs users but this operation isn't possible on a server.
So I have test protocol "sspi" and this protocol work fine for all user
but this protocole isnt implemented for eclipse IDE. 
 
What can i do for give right to user to change permission on cvs temp ?

 
Do you know how make "sspi" protocole  work with eclipse 3.1 ?   
 
This is a bug or an administration problem ? 
 
Thank you for your answer,
Greg
