RE: Unable to start Cygwin64 terminal after password change

["Lavrentiev, Anton (NIH/NLM/NCBI) [C]" <lavr@ncbi.nlm.nih.gov>]

More info:

Running "cygcheck -rvs" from under bash (that I could only start from cmd.exe as shown earlier)
does not seem to show anything unusual (I have only single install of Cygwin, there's no conflict
of any kind, and all the packages check out Okay).

SysDir: C:\WINDOWS\system32
WinDir: C:\WINDOWS

PWD = '/cygdrive/c/WINDOWS/system32'
HOME = '/'
CYGWIN = 'nodosfilewarning '

The only thing in that output that still does not seem right is this section
(which I can't show in its entirety, so I am redacting it):

Output from C:\cygwin64\bin\id.exe
UID: 1050182(NCBI_NT+User(1606)
GID: 1050182 groups=1050182,1049089(NCBI_NT+Group(513)
mote Desktop Users)
555(Remote Desktop Users)
545(Users)
...

Note that my username is still numeric and the second line shows some incomplete
group name that has been cut off in the middle ("mote Desktop Users")...
All other (about 20) groups that follow [...] have their numeric and textual
information correct, without any issues...

I vaguely remember having the same issue some time ago (but then my work PC was frequently bugchecking
because of a faulty memory module), and I did not tie any recent password change (if there was any at all)
with my unability to run Cygwin terminal...  That time I had to clean my registry settings pertaining
to Cygwin and then I got the terminal working back (still have a history of doing so in the support
ticket created back than).  I haven't done so just yet.  Maybe some other thing is also in the play here,
and I will gladly provide any necessary information while it persistently and reproducibly not working,
to have it fixed (rather than crudely worked around).

Thanks for looking into this.
