in computer properties the name was still ws1

I followed your instructions:
* left XP from domain
* changed winxp computer name to ws3 and sid with newsid utility (I had to
do it because I got the error saying smth like "cannot correlate user
names", sorry for my bad translation from russian)
* joined winxp to domain under name WS3
* powered off the vm
* started packet capture with "tcpdump -i eth1 -p -s 0 -w samba4.dump.txt
port 445 or port 139"
* exported keytab with "samba-tool domain exportkeytab ./samba4.keytab"
* powered on winxp
* logged in as admin and tried to rename WS3 to WS4, twice, both times a
got an error but they seem to be a bit different, first time it said smth
like the file exists already, the second time something like username is
not found.

I wasn't able to note the packet number after I've logged on, packets are
in raw. I zipped samba4 dump and keytab files and attached it.
Thanks!
