[cvsnt] cvs server : nothing known about

[Sanjeev, Neeraja (GE Infra, Energy)]

Hi,

I am working on cvsnt in my project. I tried to remove the file "cvs
remove -f GSDFiles/si03801e.gss".  After it is successful , I commited
the changes. 
But when I tried to issue a Update command, deleted files come into my
working folder.

Sometimes remove command itself keeps throwing this error message 
"cvs server: nothing known about `GSDFiles/si03801e.gss'". I am not able
to  fix this.

Same operation is working with other set of files.  

Any help would be appreciated.

Thanks,
Neeraja.
