When invoking a cygwin bash shell window, I'm getting the following message:
***message begins*** Your group is currently "mkgroup". This indicates that neither your gid nor your pgsid (primary group associated with your SID) is in /etc/group. The /etc/group (and possibly /etc/passwd) files should be rebuilt. See the man pages for mkpasswd and mkgroup then, for example, run mkpasswd -l [-d] > /etc/passwd mkgroup -l [-d] > /etc/group Note that the -d switch is necessary for domain users. ***message ends*** An attempt to run mkgroup ends in: $ mkgroup SYSTEM:S-1-5-18:18: mkgroup (101): [1355] The specified domain either does not exist or could not be contacted.

It may be related to another problem I'm experiencing (reported in http://cygwin.com/ml/cygwin/2010-04/msg00740.html) in some mysterious (and obviously indirect) manner. Any suggestions? The output of running cygcheck -s -v -r is attached.
