We are also plagued by this problem. One of our CVS servers is running
NT -- please don't ask why. :,) Before I joined the company, everyone
was accessing the CVS repository using "local" access via CIFS -- again
please don't ask why. :,) This access method was causing all kinds
of performance, permission, and locking problems. So, I recommended
setting up Cygwin OpenSSH on this server to solve these problems.
Although using ssh solved the above problems, we noticed that people
started to get locked out of their NT accounts -- they couldn't login,
access email, map shares, etc. We traced the problem down to the
combination of using ssh *and* that we had a three invalid logons will
lock the account policy.
Unfortunately, because of the above problem most people are still using
"local" access even when remote. This causes CVS operations to typically
run 10 - 20 times slower than when using client/server mode. Sigh...

Corrina, thanks for the above.

Mark, thanks for tracking down this problem.
