unable to de-instal

After selecting the databases to deinstall, one needs to give in your password.
After that I do receive a serious error:
the targetnode “nbphe01” which is the name of my machine is not accepted by the argbatch command.

if you like to delete a database via argbatch you have to use the exact name of your target machine (possibly with domain name). To find out, have a look in the Tamino manager or submit an appropriate argbatch command.
