CVS Update problem : cannot rename file .new..buildnum to .buildn um

[Viraj Purang]

I am using a Windows 2003 server (problem also occurs on a Windows 2000
professional laptop).

Everytime I try to "cvs update" a file called ".buildnum" 

I get an error : 
"cannot rename file .new..buildnum to .buildnum"

This is true for all files which have been changed on client workspace 
and are thus different from the server.

What could be the possible problem ?

Another interesting issue is that this problem occurs only when I am using a
Perl script to 
do that CVS update.Manual updated are all ok.

I did make sure that environment in both the 
cases is same.
