xwindows required for config tool?

We are running NW2004s on AIX UNIX DB2. Can you run the configtool from your windows front end PC by copying the "configtool" directory to your windows PC and running configtool.bat? Someone told me you can only run this on the sever side with Xwindows. When attempting to connect to the configtool remotely via a windows server, we get the following message

"Secure Store lib Dir does not exist /sapmnt/ND2/global/security/lib\tools"
