Thanks, I did try a clean install of cygwin.  This has not resolved the issue. I think what's happened is that some of all files modified by by various command line programs (git, rsync, etc.) in cygwin have ended up with permissions that didn't carry across with the new Windows installation.  In the [Security] tab for these files or directories, under "Group or user names", it lists the owner as "Account Unknown(S-...)".  In some cases, these files are completely inaccessible and I can't even take ownership or change the permissions.  I have to either restore them from a backup or boot to a Linux environment to access them.  - Brent
