r21475: Updated vm_get_ip.pl to read the name of the environment variable containing the VM path from the command line.

wintest_2k3_dc.sh is a new script which will run a group of tests against a Windows 2003 DC.
The group of tests to run should be passed in on the command line.
These tests were taken from the source/script/tests/test_win2k3.sh script.

tests_win2k3_dc.sh is a new script intended to be called by 'make wintest_dc' (patch to source/main.mk forthcoming).
This is intended to provide the basis for Windows 2003 DC testing in the build farm.

In order to use these tests, you should have a DC setup as a VM in VMware server.

This process is not automated yet, but can be done by following a few steps:

1. Prepare a Windows 2003 VM in VMware Server by downloading and extracting:
		svn://svn.samba.org/home/svn/samba/branches/SOC/bnh/vm_setup.tar.gz
	and following the instructions in the README file.

2. Copying the following file onto the filesystem of the VM configured in step 1:
		svn://svn.samba.org/home/svn/samba/branches/SOC/bnh/dcpromo_2k3dc_newdomain.answerfile.txt
	and use it to promote the VM.
	For example: "dcpromo /answer:<path to answerfile>"

3. On the system you are testing from, set the environment variable WINTESTCONF, and SRCDIR.
	WINTESTCONF should point to the path of a test_win.conf file modified for your environment.
	There's a default copy in source/script/tests/win/test_win.conf.
	SRCDIR should point to the base of your Samba 4 source tree.

At that point, you should be able to run wintest_2k3_dc.sh by passing a group of tests at the command line.
For example: source/script/tests/win/wintest_2k3_dc.sh RPC-DRSUAPI
