[cvsnt] failed to create lock directory?

[Bilge TUTAK]

I installed the cvsnt to my local machine.The OS is WinXP Pro. When I am
trying to commit some files, I get the following error. I can commit some
files and directories without any problem, but in some directories and files
I get this error.
cvs server: failed to create lock directory for
`I:/cvsrepo/test/english_web/people/assistants'
(I:/cvsrepo/test/english_web/people/assistants/#cvs.lock): No such file or
directory
cvs server: lock failed - giving up
cvs [server aborted]: lock failed - giving up

Also when I am trying to add new contents to my cvs repository, the cvsnt
server crashes and asks for a crash dump.

Does anyone have an idea?

I am using the cvsnt built 2.0.10

Thanx,
Bilge
