Sounds very strange to me. What if you have say 50 repositories and therefore 50 CVSROOT/group files, how can the operating system know which are valid and which are not for a particular cvs call?? And how do you tell it to include the group file from CVSROOT into its scope of groups? What the OP is saying is that CVSNT is suddenly not reading *CVSROOT/group* and therefore not getting the internal CVS defined user groups and therefore not correctly giving access to certain users.
