[cvsnt] update failing

[Mike Kay]

Greetings.  We have been happily using CVSNT with Wincvs for months with
no issues. Suddenly this weekend the coder got the following error
message:

cvs commit -f -m "update account number" --
TelusApp\WebAdmin\Web\AnalysisMasterPage.master (in directory
C:\application\development\development\19Mar2009\)
cvs server: Up-to-date check failed for
`TelusApp/WebAdmin/Web/AnalysisMasterPage.master'
cvs [server aborted]: correct above errors first!

***** CVS exited normally with code 1 *****

Not sure how to approach troubleshooting.  Any help or advice most
appreciated.
