what is the initial admin password ?

now i want to admin it with the web interface but i don't know the admin password. what is it ?

web admin

also in the intalled directory i can't found the ejabberdctl.exe utility. it works for win or is only a script for unix/linux OS ?

You are right, there is no access to that utility on the Windows installer. For now you can try this quick and dirty trick:

1. Copy the 'Start Ejabberd.lnk' shortcut to C:\ and rename it to 'ejabberdctl.lnk'
2. Edit the properties of that shortcut. On Destination:
   1. Replace 'werl.exe' with 'erl.exe'
   2. Replace '-sname ejabberd' with '-sname ejabberd2'
   3. Remove the rest of the text: '-env EJABBERD_SO_PATH ...'
   4. Add '-s ejabberd_ctl -extra ejabberd@MACHINENAME'. Instead of MACHINENAME you must put the machine short name (without the domain part).
3. Now open a Windows command line. For example: Start -> Run -> cmd.exe
4. Change to the place where you copied the new shortcut. For example: cd C:\
5. Execute the shorcut giving an additional option. For example: ejabberdctl.lnk status
6. I only get a response after 4 or 5 tries. If it does not answer in several tries, check the MACHINENAME.

As you can see, this method is not perfect.

You can also get an exact equivalent of the unix ejabberdctl shellscript by creating a .cmd file with the following line:

erl.exe -noinput -sname ejabberdctl -s ejabberd_ctl -extra %*

Note that it would work only if started in the same directory with ejabberd_ctl.beam file and only if erl.exe is available on the %PATH%, so you may want to modify the script to make it location-independent:

PUT_ERLANG_PATH_HERE\bin\erl.exe -pa "PUT_EJABBERD_PATH_HERE\ebin" -noinput -sname ejabberdctl -s ejabberd_ctl -extra %*
