Sometimes you want to check a user's computer with various tools, but first have to know the IP address of the workstation. Without resorting to NetWare Administrator or DOS command lines, I have madeup this VB Script you can run to get the IP address. It's by no means foolproof, but it can make your job easier.
This ZIP includes the script and source code you can use to get the IP address of a logged in user. It will make a c:\user.txt file that will display the results. You need a z: drive mapped to the sys volume for it to use nlist to get the information.
