Subject:	Strange Issue with Launching Cygwin bash and other Applications

Dear all,

After the last restart (and maybe also after an update of Cygwin last week), the first start of bash takes hideously long (about 2 minutes).  The same happens to programs like latexmk:

$ time latexmk --help
Latexmk: This is Latexmk, John Collins, 10 January 2015, version: 4.42.
[... more output ...]
Report bugs etc to John Collins <jcc8 at psu.edu>.

real    1m39.914s
user    0m0.000s
sys     0m0.015s


I did an strace on latexmk and it seems that something is querying the Active Directory of my computers domain through the VPN:

1047703 1224686 [main] perl 11652 pwdgrp::fetch_account_from_windows: line: < XXXXXXXXXXXXXXXXXXXX>
513639 1738325 [main] perl 11652 pwdgrp::fetch_account_from_windows: line: < XXXXXXXXXXXXXXXXXXXX >
525120 2263445 [main] perl 11652 pwdgrp::fetch_account_from_windows: line: < XXXXXXXXXXXXXXXXXXXX >
522731 2786176 [main] perl 11652 pwdgrp::fetch_account_from_windows: line: < XXXXXXXXXXXXXXXXXXXX >
518198 3304374 [main] perl 11652 pwdgrp::fetch_account_from_windows: line: < XXXXXXXXXXXXXXXXXXXX >

[I replaced the true group/account names for privacy reasons.]

Each query takes a little while and there are lots of them.  Some even take longer than a second.  This continues for quite a while until latexmk finally prints its help message.

I have found the queried the log of cygcheck.

How can I convince Cygwin (or one of its components) that this is bad idea and to avoid it?

Thanks in advance for your help.

Kind regards,
        -michael
